 * \brief ccRF Click example
 * 
 * # Description
 * This example demonstrates the use of an ccRF click board by showing
 * the communication between the two click boards configured as a receiver and transmitter.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger, performs the click default configuration and 
 * displays the selected application mode.
 *
 * ## Application Task
 * Depending on the selected mode, it reads all the received data or sends the desired message
 * every 2 seconds.
