We added a port to Micropython for this board, so to be able to make the first tests. We wrote several Python modules to send and receive all 4 data message types of the LoRaWAN 1.0.x and 1.1 standards. These message types are used to transport MAC commands and application data. So we were now able to communicate with TTN successfully in ABP and OTAA modes. In addition, we have written an overriding class for low level hardware control of the SX1276 module. 

More details later.
