I’ve mentioned my plans for this project during the IoT hangout session few months ago, it has finally materialized as working prototype. The blocker so far was the lack of ESP8266 RFM69 driver and free time on my end, so I’ve teamed up with Andrey Balarev to solve this. Andrey is an IoT enthusiast + embedded systems developer and has done excellent job in porting LowPowerLab’s RFM69 library for the ESP8266. He spent few weekends staring at the oscilloscope, re-writing SPI library code and managed to solve a number of challenges to get this library going. I’ve bundled his driver code with MQTT to get a beautifully working prototype that forwards RFM69 traffic to MQTT and vice versa.
