1. Introduction

The YoctoHub-Wireless-SR module is a 60x58mm module enabling you to control other Yoctopuce modules through a wireless network connection. Seen from the outside, this module behaves exactly like a standard computer running a VirtualHub1: same interface, same functionalities.

The YoctoHub-Wireless-SR is designed to be easily deployed and to not require any specific maintenance. In the opposite to a mini-computer, it does not have a complex operating system. Some simple settings allow you to use it in many kinds of network environments. These settings can be modified manually or automatically through USB. Therefore, the YoctoHub-Wireless-SR is much more suited to industrialization than a mini-computer. However, you cannot run additional software written by the user on the YoctoHub-Wireless-SR.

The YoctoHub-Wireless-SR is not a standard USB hub with network access. Although it uses USB cables, its down ports use a proprietary protocol, much simpler than USB. It is therefore not possible to control, or even to power, standard USB devices with a YoctoHub-Wireless-SR.

Yoctopuce thanks you for buying this YoctoHub-Wireless-SR and sincerely hopes that you will be satisfied with it. The Yoctopuce engineers have put a large amount of effort to ensure that your YoctoHub-Wireless-SR is easy to install anywhere and easy to use in any circumstance. If you are nevertheless disappointed with this device, do not hesitate to contact Yoctopuce support2.

2.1. The YoctoHub-Wireless-SR components

Serial number

Each Yocto-module has a unique serial number assigned to it at the factory. For YoctoHub-Wireless-SR modules, this number starts with YHUBWLN2. The module can be software driven using this serial number. The serial number cannot be modified.

Logical name

The logical name is similar to the serial number: it is a supposedly unique character string which allows you to reference your module by software. However, in the opposite of the serial number, the logical name can be modified at will. The advantage is to enable you to build several copies of the same project without needing to modify the driving software. You only need to program the same logical name in each copy. Warning: the behavior of a project becomes unpredictable when it contains several modules with the same logical name and when the driving software tries to access one of these modules through its logical name. When leaving the factory, modules do not have an assigned logical name. It is yours to define.

Yocto-button

The Yocto-button has two functionalities. First, it can activate the Yocto-beacon mode (see below under Yocto-led). Second, if you plug in a Yocto-module while keeping this button pressed, you can then reprogram its firmware with a new version. Note that there is a simpler UI-based method to update the firmware, but this one works even if the firmware on the module is incomplete or corrupted.

Yocto-led

Normally, the Yocto-led is used to indicate that the module is working smoothly. The Yocto-led then emits a low blue light which varies slowly, mimicking breathing. The Yocto-led stops breathing when the module is not communicating any more, as for instance when powered by a USB hub which is disconnected from any active computer.

When you press the Yocto-button, the Yocto-led switches to Yocto-beacon mode. It starts flashing faster with a stronger light, in order to facilitate the localization of a module when you have several identical ones. It is indeed possible to trigger off the Yocto-beacon by software, as it is possible to detect by software that a Yocto-beacon is on.

The Yocto-led has a third functionality, which is less pleasant: when the internal software which controls the module encounters a fatal error, the Yocto-led starts emitting an SOS in morse 3. If this happens, unplug and re-plug the module. If it happens again, check that the module contains the latest version of the firmware and, if it is the case, contact Yoctopuce support4.

Power / Control port

This port allows you to power the YoctoHub-Wireless-SR and the modules connected to it with a simple USB charger. This port also allows you to control the YoctoHub-Wireless-SR by USB, exactly like you can do it with a classic Yoctopuce module. It is particularly useful when you want to configure the YoctoHub-Wireless-SR without knowing its IP address.

Down ports

You can connect up to three Yoctopuce modules on these ports. They will then be available as if they were connected to a computer running a VirtualHub. Note that the protocol used between the YoctoHub-Wireless-SR and the USB modules is not USB but a lighter proprietary protocol. Therefore, the YoctoHub-Wireless-SR cannot manage devices other than Yoctopuce devices. A standard USB hub does not work either5. If you want to connect more than three Yoctopuce modules, just connect one or more YoctoHub-Shield6 to the back ports.

Warning: the USB connectors are simply soldered in surface and can be pulled out if the USB plug acts as a lever. In this case, if the tracks stayed in position, the connector can be soldered back with a good iron and flux to avoid bridges. Alternatively, you can solder a USB cable directly in the 1.27mm-spaced holes near the connector.

Integrated Antenna

The YoctoHub-Wireless-SR features an antenna integrated on the board. So you won't have to use an external one. Because of that integrated antenna, device orientation will have an influence on performances. Make sure you don't mount your YoctoHub-Wireless-SR in a metallic enclosure.

Overload led

The YoctoHub-Wireless-SR continuously monitors its power consumption. If it detects a global consumption of more that 2A, following an overload on one of the down ports for example, it automatically disables all the down ports and lights the overload led. To isolate the source of the issue, you can reactivate the ports one by one, monitoring the power consumption increase. Alternatively, if you know the source of the overload issue and know to have solved it, you can restart the YoctoHub-Wireless-SR to enable all its ports at once.

Note that the overload led is a protection measure which can prevent overheating, but it is not a protection guarantee against shorts.

Sleep

Usually, the YoctoHub-Wireless-SR consumes about 0.5 Watt (110mA), to which you must add the connected module consumption. But it is able to get into sleep to reduce its power consumption to a strict minimum, and to wake up at a precise time (or when an outside contact is closed). This functionality is very useful to build measuring installations working on a battery. When the YoctoHub-Wireless-SR is in sleep mode, most of the electronics of the module as well as the connected Yoctopuce modules are switched off. This reduces the total consumption to 75 µW (15 µA).

Switching to sleep and waking up can be programmed based on a schedule, controlled by software, or controlled manually with two push buttons located on the YoctoHub-Wireless-SR circuit. You can find there two pairs of contacts which enable you to shunt these two buttons.


Sleep and wake up buttons deviation.

The YoctoHub-Wireless-SR includes a switch with which you can disable the sleep mode at the hardware level. This functionality is particularly useful when developing and debugging your project, as well as when updating the firmware.

3. First steps

The aim of this chapter is to help you connect and configure your YoctoHub-Wireless-SR for the first time.

3.1. Manual configuration

You can configure your YoctoHub-Wireless-SR through its USB control port, by using the VirtualHub7.

Run the VirtualHub on your preferred computer and connect it to the power / control port of the YoctoHub-Wireless-SR. You need a USB A-MicroB cable.


Configuration: connecting your YoctoHub-Wireless-SR by USB to a computer

Launch your preferred browser on the URL of your VirtualHub. It usually is http://127.0.0.1:4444. You obtain the list of Yoctopuce modules connected by USB, among which your YoctoHub-Wireless-SR.


List of Yoctopuce modules connected by USB to your computer, among which your YoctoHub-Wireless-SR

Click on the configure button corresponding to your YoctoHub-Wireless-SR. You obtain the module configuration window. This window contains a Network configuration section.


YoctoHub-Wireless-SR module configuration window

Connection to the wireless network

You must first configure your YoctoHub-Wireless-SR to enable it to connect itself to your wifi network. To do so, click on the edit button corresponding to WLAN settings in the Network configuration section. The configuration window of the wireless network shows up:


Wireless network configuration window.

You can then decide if you wish to connect your YoctoHub-Wireless-SR to an existing network, or if you would rather manually enter the SSID of network you wish to use.

You can also configure the YoctoHub-Wireless-SR for it to generate its own wireless network in ad-hoc mode. You can then connect yourself directly on the YoctoHub-Wireless-SR without having to go through an infrastructure server (access point). However, be aware that the ad-hoc mode has important limitations compared to a real wifi network. In particular, devices under Android cannot connect themselves to it.

When you have set the wireless network parameters, and possibly tested them, you can click on the OK button to close this configuration window and go back to the main configuration window.

If needed, you can also configure which IP address must be assigned to the YoctoHub-Wireless-SR. To do so, click on the edit button opposite to the IP addressing line in the main window.

You can then choose between a DHCP assigned IP address or a fixed IP address for your YoctoHub-Wireless-SR module. The DHCP address is recommended in so much as this functionality is supported by most ADSL routers (its the default configuration). If you do not know what a DHCP server is but are used to connect machines on your network and to see them work without any problem, do not touch anything.

You can also choose the network name of your YoctoHub-Wireless-SR. You can then access your YoctoHub-Wireless-SR by using this name rather than its IP address. When the network part is configured, click on the Save button to save your changes and close the configuration window. These modifications are saved in the persistent memory of the YoctoHub-Wireless-SR, they are kept even after the module has been powered off.

Click on the serial number corresponding to your YoctoHub-Wireless-SR. This opens your module property window:


The YoctoHub-Wireless-SR properties

This window contains a section indicating the state of the YoctoHub-Wireless-SR network part. You can find there its MAC address, current IP address, and network name. This section also provides the state of the network connection. Possible states are:

When you have checked that your module does indeed have a valid IP address, you can close the property window, stop your VirtualHub, and disconnect your USB cable. They are not needed anymore.

From now on, you can access your YoctoHub-Wireless-SR by typing its IP address directly in the address field of your preferred browser. The module answers to the standard HTTP port, but also to the 4444 port used by the VirtualHub. If your module IP address is 192.168.0.10, you can therefore access it with the http://192.168.0.10 URL.


The YoctoHub-Wireless-SR interface is identical to that of a VirtualHub.

If you have assigned a name to your YoctoHub-Wireless-SR, you can also use this name on the local network. For example, if your have used the yoctohub network name, you can contact the module with the http://yoctohub URL under Windows and the http://yoctohub.local URL under Mac OS X and Linux. Note that this technique is limited to the subnet of the YoctoHub-Wireless-SR. If you want to contact the module by name from another network, you must use a classic DNS infrastructure.

3.2. Automated configuration

You can industrialize the YoctoHub-Wireless-SR network configuration. You can find in the following chapters of this documentation the description of the programming functions enabling you to read the Ethernet address (MAC address) of a module, and to configure all of its network parameters.

The network configuration functions are also available as command lines, using the YNetwork utility software available in the command line programming library 8.

After having set some parameters by software, make sure to call the saveToFlash() function to ensure that the new settings are saved permanently in the module flash memory.

3.3. Connections

Power supply

The YoctoHub-Wireless-SR must be powered by the USB control socket.

USB

Simply connect a USB charger in the power / control port port, but make sure that the charger provides enough electric power. The YoctoHub-Wireless-SR consumes about 110mA, to which you must add the power consumption of each submodule. The YoctoHub-Wireless-SR is designed to manage a maximum of 2A. Therefore, we recommend a USB charger able to deliver at least 2A. Moreover, you must make sure that the total power consumption of the set "hub + submodules" does not go above this limit.


The YoctoHub-Wireless-SR can be powered by a regular USB charger

Sub-modules

The YoctoHub-Wireless-SR is able to drive all the Yoctopuce modules of the Yocto range. These modules can be directly connected to the down ports. They are automatically detected. For this, you need Micro-B Micro-B USB cables. Whether you use OTG cables or not does not matter.


Connecting sub-modules with USB cables

Alternatively, you can connect your modules by directly soldering electric cables between the YoctoHub-Wireless-SR and its sub-modules. Indeed, all the Yoctopuce modules have contacts designed for direct cabling. We recommend you to use solid coper ribbon cables, with a 1.27mm pitch. Solid copper ribbon cable is less supple than threaded cable but easier to solder. Pay particular attention to polarity: the YoctoHub-Wireless-SR, like all modules in the Yoctopuce range, is not protected against polarity inversion. Such an inversion would likely destroy your devices. Make sure the positions of the square contacts on both sides of the cable correspond.


Sub-module connection with ribbon cable

The YoctoHub-Wireless-SR is designed so that you can fix a single width module directly on top of it. To do so, you need screws, spacers9, and a 1.27mm pitch connector10. You can thus transform your USB Yoctopuce module into a network module while keeping a very compact format.


Fixing a module directly on the hub

Beware, the YoctoHub-Wireless-SR is designed to drive only Yoctopuce modules. Indeed, the protocol used between the YoctoHub-Wireless-SR and the sub-modules is not USB but a much lighter proprietary protocol. If, by chance, you connect a device other than a Yoctopuce module on one of the YoctoHub-Wireless-SR down ports, this port is automatically disabled to prevent damages to the device.

4. Assembly

This chapter provides important information regarding the use of the YoctoHub-Wireless-SR module in real-world situations. Make sure to read it carefully before going too far into your project if you want to avoid pitfalls.

4.1. Fixing

While developing your project, you can simply let the hub hang at the end of its cable. Check only that it does not come in contact with any conducting material (such as your tools). When your project is almost at an end, you need to find a way for your modules to stop moving around.


Examples of assembly on supports

The YoctoHub-Wireless-SR module contains 3mm assembly holes. You can use these holes for screws. The screw head diameter must not be larger than 8mm or the heads will damage the module circuits.

Make sure that the lower surface of the module is not in contact with the support. We recommend using spacers. You can fix the module in any position that suits you: however be aware that the YoctoHub-Wireless-SR electronic components, in particular the network part, generate heat. You must not let this heat accumulate.

4.2. Fixing a sub-module

The YoctoHub-Wireless-SR is designed so that you can screw a single width module directly on top of it. By single width, we mean modules with a 20mm width. All the single width modules have their 5 assembly holes and the USB socket in the same position. The sub-module can be assembled with screws and spacers. At the back of the YoctoHub-Wireless-SR and sub-module USB connectors, there are a set of 4 contacts enabling you to easily perform an electrical connection between the hub and the sub-module. If you do not feel sufficiently at ease with a soldering iron, you can also use a simple Micro-B Micro-B USB cable, OTG or not.


Fixing a module directly on the hub

Make sure to mount your module on the designed side, as illustrated above. The module 5 holes must correspond to the YoctoHub-Wireless-SR 5 holes, and the square contact on the module must be connected to the square contact on the YoctoHub-Wireless-SR down port. If you assemble a module on the other side or in another way, the connector polarity will be inverted and you risk to permanently damage your equipment.

All the accessories necessary to fix a module on your YoctoHub-Wireless-SR are relatively usual. You can find them on the Yoctopuce web site, as on most web sites selling electronic equipment. However, beware: the head of the screws used to assemble the sub-module must have a maximum head diameter of 4.5mm, otherwise they could damage the electronic components.

5. Using the YoctoHub-Wireless-SR

Apart from providing network access to the Yoctopuce devices, the YoctoHub-Wireless-SR enables you to test and configure your Yoctopuce modules. To do so, connect yourself to your YoctoHub-Wireless-SR with your favorite web browser11. Use the IP address of the YoctoHub-Wireless-SR or its network name, for example http://192.168.0.10. The list of the connected modules should appear.


YoctoHub-Wireless-SR web interface

5.1. Locating the modules

The main interface displays a line per connected module; if you have several modules of the same model, you can locate a specific module by clicking on the corresponding beacon button: it makes the blue led of the module start blinking and displays a blue disk at the beginning of the corresponding line in the interface. Pressing the Yocto-button of a connected module has the same effect.


Yocto-button (1) and localization led (2) of the Yocto-Demo module. These two elements are usually placed in the same location, whatever the module.

5.2. Testing the modules

To test a module, simply click on the serial number of a module in the interface, a window specific to the module opens. This window generally allows you to activate the main functions of the module. Refer to the User's guide of the corresponding module for more details 12.


Property window of the Yocto-Demo module, obtained from the YoctoHub-Wireless-SR interface

5.3. Configuring modules

You can configure a module by clicking on the corresponding configure button in the main interface. A window, specific to the module, then opens. This window allows you minimally to assign a logical name to the module and to update its firmware. Refer to the User's guide of the corresponding module for more details.


"Configuration" window of the Yocto-Demo module

5.4. Upgrading firmware

The Yoctopuce modules are in fact real computers, they even contain a small web server. And, as all computers, it is possible to update their control software (firmware). New firmware for each module are regularly published, they generally allow you to add new functionalities to the module, and/or to correct a hypothetical bug13.

To update a module firmware, you must first get the new firmware. It can be downloaded from the module product page on the Yoctopuce web site14. The interface offers also a direct link if it detects that the firmware is not up-to-date 15. Firmware is available as .byn files of a few tens of kilobytes. Save the one you are interested in on your local disk.


Firmware update window

When the firmware file is locally available, open the module configuration window and click on the upgrade button. The interface asks you to select the firmware file you wish to use. Enter the file name and click on Upload. From then on, everything is automatically performed: the YoctoHub-Wireless-SR restarts the module in "update" mode, updates the firmware, then restarts the module in normal mode. The module configuration settings are kept. Do not disconnect the module during the update process.

The YoctoHub-Wireless-SR firmware can be updated in the same manner.

If control is lost during a firmware update (power failure or unwanted disconnection), it is always possible to manually force a firmware reload, even if the sub-module does not even appear in the YoctoHub-Wireless-SR window. In this case, disconnect the module, and reconnect it while keeping the Yocto-button pressed. This starts the module in "update" mode. You can restart the firmware update process.

6. Access control

The YoctoHub-Wireless-SR is able to perform access control to protect your Yoctopuce devices. Click on the configure button on the line matching the YoctoHub-Wireless-SR in the user interface.


Click on the "configure" button on the first line

Then the configuration window for the YoctoHub-Wireless-SR shows up.


The YoctoHub-Wireless-SR configuration window.

Access control can be configured from the Incoming connections section. There are two levels of access control.

6.1. Protected "admin" access

The admin password locks write access on the modules. When the admin password is set, only users using the admin login are allowed read and write access to the modules. The users using the admin login can configure the modules seen by this YoctoHub-Wireless-SR as they wish.

6.2. Protected "user" access

The user password locks read access to the Yoctopuce modules. When set, any use without password becomes impossible. The user access type allows only read-only access to the modules, that is only to consult the states of the modules. If you simultaneously create "admin" and "user" access controls, users with a "user" login cannot modify the configuration of modules seen by this YoctoHub-Wireless-SR.

If you configure an admin access, without configuring a user access, users are still able to read your device values without any password.

To set up YoctoHub-Wireless-SR access, click the edit button on the line Authentication to read the information from the devices or Authentication to write information to the devices

6.3. Access control and API

Warning, the access control has an impact on Yoctopuce API behavior when trying to connect to this YoctoHub-Wireless-SR. With Yoctopuce API, access control is handled at RegisterHub() function call level. You need to provide the YoctoHub-Wireless-SR address as follow: login:password@address:port, here is an exemple:


yRegisterHub("admin:mypass@192.168.0.10:4444",errmsg);

6.4. Deleting passwords

If you forget your YoctoHub-Wireless-SR password, the only way to regain control is to reset all the settings to the default value. To do so, find a USB cable for the YoctoHub-Wireless-SR and connect it to a computer running the VirtualHub16 while keeping the Yocto-button pressed. This forces the YoctoHub-Wireless-SR to start in firmware update mode. It then appears in the VirtualHub below the module list. Click on its serial number and select a firmware file to load on the module. When the firmware is reloaded with this method, the module is reset to the factory settings, without access control.

7. Interaction with external services

The YoctoHub-Wireless-SR can publish the state of connected devices on any web server. The values are posted on a regular basis and each time one of them changes significantly. This feature, named HTTP Callback, enables you to interface your Yoctopuce devices with many web services.

7.1. Configuration

To use this feature, just click on the configure button located on the line matching the YoctoHub-Wireless-SR on the main user interface. Then look for the Outgoing calbacks section and click on the edit button.


Just click on the "Configure" button on the first line.


Then edit the "Outgoing callbacks" section.

The callback configuration window shows up. This window enables you to define how your YoctoHub-Wireless-SR interacts with an external web server. Several interaction types are at your disposal. For each type, a specific wizard will help you enter appropriate parameters

7.2. Emoncms

Emoncms.org is an open-source cloud service where you can register to upload your sensor data. It will let you view your measures in real-time over the Internet, and draw historical graphs, without writing a single line of code. You just have to enter in the configuration window your own API key, as provided by Emoncms, and allocate an arbitrary node number to YoctoHub-Wireless-SR.

It is also possible to install Emoncms on your own server, to keep control on your data. You will find more explanations about this on Yoctopuce blog17.

Yoctopuce is not affiliated with Emoncms.org.

7.3. Valarm.net

Valarm is a professional cloud service where you can register to upload your sensor data, with some advanced features like remote configuration of Yoctopuce devices and measure geolocation.

Valarm is a reseller for Yoctopuce products, but Yoctopuce is not otherwise affiliated with Valarm.

7.4. ThinkSpeak

ThingSpeak18 is another free cloud service. It enables you not only to trace graphs with data coming from your Yoctopuce sensors, but also to trigger some actions based on conditions set on incoming measures. The UI is not as friendly as Emoncms, but you can find on the Yoctopuce blog 19 how to configure your YoctoHub-Wireless-SR to post data directly on ThinkSpeak.

Yoctopuce is not affiliated to ThingSpeak.

7.5. Microsoft Azure

Azure is Microsoft cloud computing platform, including a collection of integrated services - database, computing, etc. For more details, see azure.microsoft.com. You can upload sensor data directly to an Azure Mobile Service, using the standard NoSQL Rest API.

Yoctopuce is not affiliated with Microsoft.

7.6. Xively (previously Cosm)

Xively is a commercial cloud service where you might be able to register to upload your sensor data. Note that since end of 2014, Xively is focusing on enterprise and OEM customers, and might therefore not be available to everyone. For more details, see xively.com.

Yoctopuce is not affiliated with Xively.

7.7. InfluxDB

InfluxDB is an open-source database for time series, metrics and events. It is very efficient to retrieve measure series for a given time range, even when averaging on-the-fly. You can easily install it on your own computer to record and graph your sensor data. There is a step-by-step guide on how to configure InfluxDB and Grafana to graph Yoctopuce sensors on the Yoctopuce blog 20.

Yoctopuce is not affiliated to InfluxData nor to Grafana.

7.8. Yocto-API callback

With some programming environments, the full Yoctopuce API can be used to drive devices in HTTP callback mode. This way, a web server script can take control of Yoctopuce devices installed behind a NAT filter without having to open any port. Typically, this allows you to control Yoctopuce devices running on a LAN behind a private DSL router from a public web site. The YoctoHub-Wireless-SR then acts as a gateway. All you have to do is to define the HTTP server script URL and, if applicable, the credentials needed to access it. On the server script, you would initialize the library using the following call:

RegisterHub("http://callback");

There are two possibilities to use the Yoctopuce API in callback mode. The first one, available in PHP, Java and Node.JS is using pure HTTP callbacks. The YoctoHub-Wireless-SR posts its complete state to the server, and receives commands in return from the server script. There are however some limitations with this mode: complex interactions, such as retrieving data from the datalogger, are not possible.

The second mode API callback mode is using WebSocket callbacks. It is currently only available in Java and Node.JS. WebSockets are a standard extension of HTTP, providing a full bidirectional exchange channel over an HTTP connection. When a server script is connected by a YoctoHub-Wireless-SR over a Websocket callback connection, the fully Yoctopuce API can be used, without any limitation.

7.9. User defined callback

The "User defined callback" allow you to fully customize the way the YoctoHub-Wireless-SR interacts with an external web site. You need to provide the URL of the web server where you want the hub to post data. Note that only HTTP protocol is supported (no HTTPS).


The callback configuration window.

If you want to secure access to your callback script, you can setup a standard HTTP authentication. The YoctoHub-Wireless-SR knows how to handle standard HTTP authentication schemes: simply fill in the user and and password fields needed to access the URL. Both Basic and Digest authentication are supported. However, Digest authentication is highly recommended, since it uses a challenge mechanism that avoids sending the password itself over the Internet, and prevents replays.

The YoctoHub-Wireless-SR posts the advertised values21 on a regular basis, and each time one of these values changes significantly. You can change the default delay between posts.

Tests

To help you debug the process, you can visualize with the YoctoHub-Wireless-SR the answer to the callback sent by the web server. Click on the test button when all required fields are filled. When the result meets your expectations, close the debug window and then click on the "Ok" button.

Format

Values are posted in one of the following formats:

1. If the function has been assigned a logical name:

FUNCTION_NAME = VALUE

2. If the module has been assigned a logical name, but not the function:

MODULE_NAME#HARDWARE_NAME = VALUE

3. If no logical name has been set:

SERIAL_NUMBER#HARDWARE_NAME = VALUE

Here is a short PHP script allowing you to visualize the data posted by the callback and the result in the debug window:


<?php
  Print(Date('H:i:s')."\r\n");
  foreach ($_POST as $key=>$value) {
      Print("$key=$value\r\n");
  }
?>


Callback test results with a Yocto-PowerRelay and a Yocto-Temperature.

8. Programming

8.1. Accessing connected modules

The YoctoHub-Wireless-SR behaves itself exactly like a computer running a VirtualHub. The only difference between a program using the Yoctopuce API with modules in native USB and the same program with Yoctopuce modules connected to a YoctoHub-Wireless-SR is located at the level of the registerHub function call. To use USB modules connected natively, the registerHub parameter is usb. To use modules connected to a YoctoHub-Wireless-SR, you must simply replace this parameter by the IP address of the YoctoHub-Wireless-SR. For instance, in Delphi:


YRegisterHub("usb",errmsg);

becomes


YRegisterHub("192.168.0.10",errmsg); // The hub IP address is 192.168.0.10

8.2. Controlling the YoctoHub-Wireless-SR

From the programming API standpoint, the YoctoHub-Wireless-SR is a module like the others. You can perfectly manage it from the Yoctopuce API. To do so, you need the following classes:

Module

This class, shared by all Yoctopuce modules, enables you to control the module itself. You can drive the Yocto-led, know the USB power consumption of the YoctoHub-Wireless-SR, and so on.

Network

This class enables you to manage the network part of the YoctoHub-Wireless-SR. You can control the link state, read the MAC address, change the YoctoHub-Wireless-SR IP address, know the power consumption on PoE, and so on.

HubPort

This class enables you to manage the hub part. You can enable or disable the YoctoHub-Wireless-SR ports, you can also know which module is connected to which port.

Files

This class enables you to access files stored in the flash memory of the YoctoHub-Wireless-SR. The YoctoHub-Wireless-SR contains a small file system which allows you to store, for example, a web application controlling the modules connected to the YoctoHub-Wireless-SR.

WakeMonitor

This class enables you to monitor the sleep mode of the YoctoHub-Wireless-SR.

WakeSchedule

This class enables you to schedule one or several wake ups for the YoctoHub-Wireless-SR.

You can find some examples on how to drive the YoctoHub-Wireless-SR by software in the Yoctopuce programming libraries, available free of charge on the Yoctopuce web site.

9. Sleep mode

The YoctoHub-Wireless-SR includes a real time clock (RTC) powered by a super capacitor. This capacitor charges itself automatically when the module is powered. But it is able to keep time without any power for several days. This RTC is used to drive a sleep and wake up system to save power. You can configure the sleep system manually through an interface or drive it through software.

9.1. Manual configuration of the wake ups

You can manually configure the wake up conditions by connecting yourself on the interface of the YoctoHub-Wireless-SR. In the Wake-up scheduler section of the main configuration window, click on the setup button corresponding to one of the "wakeup-schedule". This opens a window enabling you to schedule more or less regular wake ups. Select the boxes corresponding to the wanted occurrences. Empty sections are ignored.


Wake up configuration window: here every 10 minutes between 9h and 17h.

Likewise, you can configure directly in the YoctoHub-Wireless-SR interface the maximal wake up duration, after which the module automatically goes back to sleep. If your YoctoHub-Wireless-SR is running on batteries, this ensures they do not empty even if no explicit sleep command is received.

9.2. Configuring the wake up system by software

At the programming interface level, the wake up system is implemented with two types of functions: the wakeUpMonitor function and the wakeUpSchedule function.

wakeUpMonitor

The wakeUpMonitor function manages wake ups and sleep periods, proper. It provides all the instant managing functionalities : instant wake up, instant sleep, computing the date of the next wake up, and so on...

The wakeUpMonitor function enables you also to define the maximum duration during which the YoctoHub-Wireless-SR stays awake before automatically going back to sleep.

wakeUpSchedule

The wakeUpSchedule function enables you to program a wake up condition followed by a possible sleep. It includes five variables enabling you to define correspondences on minutes, hours, days of the week, days of the month, and months. These variables are integers where each bit defines a correspondence. Schematically, each set of minutes, hours, and days is represented as a set of boxes with each a coefficient which is a power of two, exactly like in the corresponding interface of the YoctoHub-Wireless-SR.

For example, bit 0 for the hours corresponds to hour zero, bit 1 corresponds to hour 1, bit 2 to hour 2, and so on.


To each box is assigned a power of two

Thus, to program the YoctoHub-Wireless-SR for it to wake up every day at noon, you must set bit 12 to 1, which corresponds to the value 2^12 = 4096.


Example for a wake up at 12h

For the module to wake up at 0 hour, 6 hours, and 12 hours, you must set the 0, 6, and 12 bits to 1, which corresponds to the value 2^0 +2^6 +2^12 = 1 + 64 + 4096 = 4161


Example for wake ups at 0, 6, and 12h

Variables can be combined. For a wake up to happen every day at 6h05, 6h10, 12h05, and 12h10, you must set the hours to 2^6 + 2^12 = 4060, minutes to 2^5 and 2^10 = 1056. Variables remaining at the zero value are ignored.


Example for wake ups at 6H05, 6h10, 12h05, and 12h10

Note that if you want to program a wake up at 6h05 and 12h10, but not at 6h10 and 12h05, you need to use two distinct wakeUpSchedule functions.

This paradigm allows you to schedule complex wake ups. Thus, to program a wake up every first Tuesday of the month, you must set to 1 bit 1 of the days of the week and the first seven bits of the days of the month.


Example for a wake up every first Tuesday of the month

Some programming languages, among which JavaScript, do not support 64 bit integers. This is an issue for encoding minutes. Therefore, minutes are available both through a 64 bit integer minutes and two 32 bit integers minutesA and minutesB. These 32 bit integers are supposed to be available in any current programming language.


Minutes are also available in the shape of two 32 bit integers

The wakeUpSchedule function includes an additional variable to define the duration, in seconds, during which the module stays awake after a wake up. If this variable is set to zero, the modules stays awake.

The YoctoHub-Wireless-SR includes two wakeUpSchedule functions, enabling you to program up to two independent wake up types.

10. Personalizing the web interface

Your YoctoHub-Wireless-SR contains a small embedded file system, allowing it to store personalized files for its own use. You can manipulate the file system thanks to the yocto_files library. You can store there the files you want to. If need be, you can store a web application enabling you to manage modules connected to your YoctoHub-Wireless-SR.

10.1. Using the file system

Interactive use

The YoctoHub-Wireless-SR web interface provides a succinct interface to manipulate the content of the file system: simply click the configuration button corresponding to your module in the hub interface, then the manage files button. The files are listed and you can view them, erase them, or add new ones (downloads).

Because of its small size, the file system does not have an explicit concept of directories. You can nevertheless use the slash sign "/" inside file names to sort them as if they were in directories.

Programmed use

Use the yocto_files library to manage the file system. Basic functions are available:

A piece of software using a well designed file system should always start by making sure that all the files necessary for its working are available on the module and, if needed, upload them on the module. We can thus transparently manage software updates and application deployment on new modules. To make file versions easier to detect, the get_list method returns for each file a 32 bit signature called CRC (Cyclic Redundancy Check) which identifies in a reliable manner the file content. Thus, if the file CRC corresponds, there is less than one chance over 4 billions that the content is not the correct one. You can even compute in advance in your software the CRC of the content you want, and therefore check it without having to download the files. The CRC function used by the Yoctopuce file system is the same as Ethernet, Gzip, PNG, etc. Its characteristic value for the nine character string "123456789" is 0xCBF43926.

HTTP use

You can access the files that your have downloaded on your YoctoHub-Wireless-SR by HTTP at the root of the module (at the same level as the REST API). This allows you to load personalized HTML and Javascript interface pages, for example. You cannot, however, replace the content of a file preloaded on the module, you can only add new ones.

UI and optimisation

Since you can store files on the hub file system, you can easily build a web application to control the devices connected to the hub and store it directly on the hub. This is a very convenient way to build system remote controlled by tablets or smart phones. However the web server embedded in the hub have limited connectivity capabilities: only a few number of sockets can be opened at the same time. Since most web browsers tend to open as many connection as they can to load all elements in a web page, this might lead to very long loading time. To prevent this, try to keep your UI pages as compact as possible by embedding the javascript, CSS code and if possible, images in base64 code.

10.2. Limitations

The file system embedded on your YoctoHub-Wireless-SR has some technical limitations:

11. High-level API Reference

This chapter summarizes the high-level API functions to drive your YoctoHub-Wireless-SR. Syntax and exact type names may vary from one language to another, but, unless otherwise stated, all the functions are available in every language. For detailed information regarding the types of arguments and return values for a given language, refer to the definition file for this language (yocto_api.* as well as the other yocto_* files that define the function interfaces).

For languages which support exceptions, all of these functions throw exceptions in case of error by default, rather than returning the documented error value for each function. This is by design, to facilitate debugging. It is however possible to disable the use of exceptions using the yDisableExceptions() function, in case you prefer to work with functions that return error values.

This chapter does not explain Yoctopuce programming concepts, in order to stay as concise as possible. You will find more details in the documentation of the devices you plan to connect to your YoctoHub-Wireless-SR.

11.1. Yocto-hub port interface

YHubPort objects provide control over the power supply for every YoctoHub port and provide information about the device connected to it. The logical name of a YHubPort is always automatically set to the unique serial number of the Yoctopuce device connected to it.

In order to use the functions described here, you should include:

It is recommended to use a well-randomized WEP128 key using 26 hexadecimal digits to maximize security. Remember to call the saveToFlash() method and then to reboot the module to apply this setting.

Parameters :

ssidthe name of the network to connect to
securityKeythe network key, as a character string

Returns :

YAPI_SUCCESS when the call succeeds.

On failure, throws an exception or returns a negative error code.

More precisely, TYPE is the type of the function, NAME it the name used for the first access to the function, SERIAL is the serial number of the module if the module is connected or "unresolved", and FUNCTIONID is the hardware identifier of the function if the module is connected. For example, this method returns Relay(MyCustomName.relay1)=RELAYLO1-123456.relay1 if the module is already connected or Relay(BadCustomeName.relay1)=unresolved if the module has not yet been connected. This method does not trigger any USB or TCP transaction and can therefore be used in a debugger.

The callback is invoked only during the execution of ySleep or yHandleEvents. This provides control over the time when the callback is triggered. For good responsiveness, remember to call one of these two functions periodically. To unregister a callback, pass a null pointer as argument.

Parameters :

callbackthe callback function to call, or a null pointer. The callback function should take two arguments: the function object of which the value has changed, and the character string describing the new advertised value.

YWireless target softAPNetwork ssid securityKey

This function can only be used with the YoctoHub-Wireless-g.

When a security key is specified for a SoftAP network, the network is protected by a WEP40 key (5 characters or 10 hexadecimal digits) or WEP128 key (13 characters or 26 hexadecimal digits). It is recommended to use a well-randomized WEP128 key using 26 hexadecimal digits to maximize security. Remember to call the saveToFlash() method and then to reboot the module to apply this setting.

Parameters :

ssidthe name of the network to connect to
securityKeythe network key, as a character string

Returns :

YAPI_SUCCESS when the call succeeds.

On failure, throws an exception or returns a negative error code.

The scan forces a disconnection from the current network. At then end of the process, the the network interface attempts to reconnect to the previous network. During the scan, the wlanState switches to Y_WLANSTATE_DOWN, then to Y_WLANSTATE_SCANNING. When the scan is completed, get_wlanState() returns either Y_WLANSTATE_DOWN or Y_WLANSTATE_SCANNING. At this point, the list of detected network can be retrieved with the get_detectedWlans() method.

On failure, throws an exception or returns a negative error code.

Level zero (DOWN_0) means that no hardware link has been detected. Either there is no signal on the network cable, or the selected wireless access point cannot be detected. Level 1 (LIVE_1) is reached when the network is detected, but is not yet connected. For a wireless network, this shows that the requested SSID is present. Level 2 (LINK_2) is reached when the hardware connection is established. For a wired network connection, level 2 means that the cable is attached at both ends. For a connection to a wireless access point, it shows that the security parameters are properly configured. For an ad-hoc wireless connection, it means that there is at least one other device connected on the ad-hoc network. Level 3 (DHCP_3) is reached when an IP address has been obtained using DHCP. Level 4 (DNS_4) is reached when the DNS server is reachable on the network. Level 5 (WWW_5) is reached when global connectivity is demonstrated by properly loading the current time from an NTP server.

Parameters :

callbackcallback function that is invoked when the result is known. The callback function receives three arguments: the caller-specific context object, the receiving function object and the boolean result
contextcaller-specific object that is passed as-is to the callback function

Returns :

nothing : the result is provided to the callback.

If you need to ensure that no space is taken by previously deleted files, you can use format_fs to fully reinitialize the filesystem.

Parameters :

pathnamepath and name of the file to remove.

Returns :

YAPI_SUCCESS if the call succeeds.

On failure, throws an exception or returns a negative error code.

11.5. Real Time Clock function interface

The RealTimeClock function maintains and provides current date and time, even accross power cut lasting several days. It is the base for automated wake-up functions provided by the WakeUpScheduler. The current time may represent a local time as well as an UTC time, but no automatic time change will occur to account for daylight saving time.

In order to use the functions described here, you should include:

js
<script type='text/javascript' src='yocto_realtimeclock.js'></script>
cpp
#include "yocto_realtimeclock.h"
m
#import "yocto_realtimeclock.h"
pas

If there is a cached value for the clock in cache, that has not yet expired, the device is considered reachable. No exception is raised if there is an error while trying to contact the device hosting the requested function.

This asynchronous version exists only in Javascript. It uses a callback instead of a return value in order to avoid blocking the Javascript virtual machine.

Parameters :

callbackcallback function that is invoked when the result is known. The callback function receives three arguments: the caller-specific context object, the receiving function object and the boolean result
contextcaller-specific object that is passed as-is to the callback function

Returns :

nothing : the result is provided to the callback.
