 * \brief ccRf2 Click example
 * 
 * # Description
 * This example demonstrates the use of ccRF 2 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver, performs the default configuration and enables the selected mode.
 * 
 * ## Application Task  
 * Depending on the selected mode, it reads the received data or sends the desired message
 * every 2 seconds. All data is being logged on the USB UART where you can track their changes.
