Ethernet hAT Support and Supply Chain Issues

by Jim E

GitHub Ethernet hAT Code

We uploaded a large set of changes to the Teledatics GUI code to add support for the Ethernet hAT. Ethernet is working quite well in our prototype boards. The way we designed the Ethernet software is so that the 802.11ah Wi-Fi device and the Ethernet device share the same IP address. This is done using something known as a network "bridge" where both devices act as a single network device as far as the operating system is concerned.

You can see the code changes in our GitHub here.

We checked in code to support the two sensor chips used in the Air Quality Sensor hAT a few weeks ago. We are currently working on the 2.4 GHz Wi-Fi hAT and the Arducam SPI camera software. All of the ‘hAT’ devices and the SPI camera will be supported in the Teledatics GUI code and will be automatically recognised if they are present.

Parts Availability and Supply Chain Issues

Two of the parts we used in our original Ethernet and Wi-Fi Gateway hAT designs are suddenly very difficult or impossible to find. So we redesigned the boards using components our CM can source. This requires that a prototype build is created and sent to us in the USA so we can test that the modifications work exactly the same as the original design.

This has pushed out our ship date by two weeks. Thank you all for your patience.
