Orhan Hirsch / Mbed 2 deprecated BLE_iot

This is a simple program to work with RedBearLab BLE Controller App. Type something from the Terminal to send to the BLEController App or vice verse. Characteristics received from App will print on Terminal.

Dependencies:   BLE_API BME280 DHT mbed nRF51822

Fork of nRF51822_SimpleChat by RedBearLab
