Ashu Joshi / Mbed 2 deprecated SensorInterface

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

Had added SerialGPS, removed it to make it stable again.
