Using TLS/SSL with our PHP library

By seb september 03,2023.

Our PHP library has supported SSL/TLS encryption for several months now. This makes it possible to use the library to connect to VirtualHub v2.0 and VirtualHub for Web. Let's take a look at how to use this feature to establish a secure connection between the library and VirtualHub.

Rotary knobs with quadrature encoder

By mvuilleu, in New stuff, august 25,2023.

The Yocto-Knob and Yocto-MaxiDisplay variants have analog inputs for connecting interface buttons: pushbuttons, rotary knobs. However, there was one type of button that was not supported: infinite rotary buttons with quadrature encoder. This limitation has now been lifted.

Web page, Yocto-Visualization, and actuators

By martinm, in Programming, august 18,2023.

One of the limitations of Yocto-Visualization is that only sensors are supported. But what if you want to monitor an experiment driven by Yoctopuce actuators and to have the result displayed with Yocto-Visualization without having to run several applications at the same time? Some time ago, we described how to integrate your own web page into Yocto-Visualization (for web). So why not simply create a web page that drives Yoctopuce actuators and then integrate it into Yocto-Visualization (for web). If you know how to code in JavaScript, it looks pretty trivial. Except that it's more subtle than it sounds.

Taking back control of a YoctoHub-GSM-4G by SMS

By mvuilleu, in New stuff and Misc, august 04,2023.

To take measures in the middle of nowhere and to transmit them to a server, the simplest solution is usually to use a low-power 4G network such as LTE-M or NB-IoT to send them periodically to a server. For example, you could use a YoctoHub-GSM-4G configured to perform HTTP callbacks to a PHP server using VirtualHub for Web. But what if one day the hub stops connecting to the server?
