Make your devices communicate flawlessly across many standards using MRF24J40MA and STM32F031K6

 * \file 
 * \brief Bee Click example
 * 
 * # Description
 * This example demonstrates the use of an BEE click board by showing
 * the communication between the two click boards.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and configures the click board.
 *
 * ## Application Task
 * Depending on the selected application mode, it reads all the received data or 
 * sends the desired message every 3 seconds.
