 * \brief Ble3 Click example
 * 
 * # Description
 * This example reads and processes data from BLE 3 clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and wake-up module.
 * 
 * ## Application Task  
 * Reads the received data.
 * 
 * ## Additional Function
 * - ble3_process ( ) - Logs all received messages on UART, and sends the certain message back to the connected device.
