This week, we'll be talking about our PHP library, HTTP callbacks, and VirtualHub for Web. In particular, how to use the three together.
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?
We're continuing to add SSL/TLS support to our libraries. This week, it's the turn of the command line library, which is upgraded to v2.0 for the occasion.
If you've ever bought a Yocto-PT100, you've probably noticed that it doesn't come with a PT100 probe, and that these probes are pretty expensive. But did you know that it's possible to make one quite easily and cheaply?
