Open the door to a world of IoT opportunities with DTCR-76DA and STM32L496AG

 * \brief iqRF Click example
 * 
 * # Description
 * IQRF Click carries the RF transceiver, operating in the 868/916 MHz frequency.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * Checks if new data byte has received in RX buffer ( ready for reading ),
 * and if ready than reads one byte from RX buffer. In the second case, 
 * the application task writes message data via UART. Results are being sent 
 * to the Usart Terminal where you can track their changes.
