The ATmega4808 mounted on AVR-IoT Wx is preprogrammed with an application ready to publish data to a Microchip account with a cloud provider, and subscribe to data sent from avr-iot.com through the cloud provider. AVR-IoT WA is preconfigured for Amazon Web Services (AWS), and AVR-IoT WG is preconfigured for Google Cloud IoT Core. The data is read from the cloud and presented to the user on avr-iot.com.
The application publishes data through Google Cloud IoT Core, and the firmware is available on GitHub: github.com/microchip-pic-avr-solutions/avr-iot-google-sensor-node-mplab.
For in-depth information about the preprogrammed demo application and how to develop your application, see the full AVR-IoT WG Application User Guide: www.microchip.com/mymicrochip/filehandler.aspx?ddocname=en607553.
Any AVR-IoT Wx kit can be reprovisioned to publish data to either Microchips sandbox account at AWS, Microchips sandbox account at Google Cloud IoT Core, or to a personal account.
