 * \file 
 * \brief LR4 Click example
 * 
 * # Description
 * This example reads and processes data from LR 4 clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver, and resets the click board to factory default configuration.
 * Then performs a group of commands for getting the FW version, the serial number, and the DevEUI.
 * After that executes the join activation by personalization command.
 * 
 * ## Application Task  
 * Checks the activation and session status and displays the results on the USB UART.
 * 
 * ## Additional Function
 * - response_handler - Parses and logs all the module responses on the USB UART.
