Garima Gupta / Mbed 2 deprecated BLE_UART_LCD_Batt_DevInfo

Use of nRF51822 to demonstrate usage of BLE-UART service provided by Nordic and the use of uLCD-144-G2. The demonstration uses the nRF Master Control Panel and nRF UART demo apps provided by Nordic and available on Google Play and Apple Store. The firmware receives data over the TX characteristic, increments it by 1 and sends it over RX characteristic. The notifications need to be enabled for the RX characteristic in the Master Control Panel to be able to receive the data. For more information check the notebook page: http://developer.mbed.org/users/garimagupta002/notebook/ble-uart-lcd-demo/

Dependencies:   4DGL-uLCD-SE BLE_API DFRobot_BLE_LoopbackUART mbed nRF51822
