 * \brief Enocean4 Click example
 * 
 * # Description
 * This example reads and processes data from EnOcean 4 clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and configures the click board.
 * 
 * ## Application Task  
 * In the receiver mode, it waits for a telegram, then replies to it with the certain message.
 * In the transmitter mode, first it sends the telegram with the certain message, 
 * then waits for a response.
 * 
 * ## Additional Function
 * - resp_message - Displays the response message on the USB UART.
 * - packet_type - Displays the packet type message on the USB UART.
 * - make_response - Driver handler function which stores data in the response buffer.
 * - log_response - Displays a response on the USB UART.
 * - send_telegram - Allows user to send a telegram to the determined destination.
 * - check_response - Waits until response is ready, then displays it on the USB UART.
