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

Stable release -onnect to the The Things Network in OTAA mode.Make sure to program your specific keys into LoRa.h - from TTN Accnt Dashboard; The program also supports reading a BME280 sensor and logging.; Serial GPS is NOT working.
