 * \brief LR5 Click example
 * 
 * # Description
 * This example reads and processes data from LR 5 Clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes UART interface and UART interrupt, and performs a module reset commands.
 * 
 * ## Application Task  
 * Performs a group of commands to get FW version, the serial number provided by Mipot,
 * DevEUI, the session status, the activation status and the parameters for the selected channel.
 * Also sets the next transmission data rate to the desired value.
 * The responses from the Mipot module to the host will be sent to the uart terminal.
 * 
 * ## Additional Function
 * - lr5_process - The general process of collecting data the module sends.
 * - make_response - Stores data from the module to the response structure.
 * - log_response -  Sends the received response from the module to the uart terminal.
 * - wait_response - Waits until response from the module is ready and then calls the 
 *                 response logging function, or writes the error message on the uart terminal.
