This program connects to the The Things Network backend in OTAA Mode. It logs sensor values from a BME 280 to the backend. Tried adding support for Grove GPS using SerialGPS library but it is not working - conflicting with mbed-rtos, so it commented. Deep Sleep for mDot implemented BUT avoiding reprogramming of the mDot config is NOT working.
Dependencies: BME280 SerialGPS libmDot mbed-rtos mbed
