 * @file main.c
 * @brief Wirepas Click Example.
 *
 * # Description
 * This example demonstrates the use of Wirepas Click board by processing
 * the incoming data and displaying them on the USB UART in sink mode, and sending data to 
 * the sinks in router mode.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration, setting device mode, node,
 * net and channel addresses, and starting stack.
 *
 * ## Application Task
 * Router mode - Sending data to the sinks at the same network.
 * Sink mode - Reads and processes all incoming data and displays them on the USB UART.
 *
 * ## Additional Function
 * - err_t wirepas_wait_response ( wirepas_t *ctx, uint8_t primitive_id )
 * - err_t wirepas_parse_frame ( wirepas_t *ctx, uint8_t primitive_id )
 * - err_t wirepas_poll_indication ( wirepas_t *ctx )
 *
 * @note
 * For the best experience use two Clicks in sink mode and one in router.
