Ro Led / Mbed 2 deprecated BLE_DHT11_Service_TemperatureHumidity

Project aiming to do a Bluetooth Low Energy IoT devices, which measure temperature and humidity. Bluetooth achieved with the IDB05A1 shield. Temperature/humidity achieved with a DHT11 sensor. Project working, tested on an STM32 L476 board.

Dependencies:   BLE_API X_NUCLEO_IDB0XA1 mbed
