// *********************************************************************
// Example of simple RF receiving.
//
// Intended for:
//   HW: - (DC)TR-72D + CK-USB-04x development kit
//
//   OS: - v4.06D
//
// Description:
//   - This example shows how to make a receiver.
//   - The transceiver permanently attempts to receive RF packets.
//     If any packet is received:
//     - LED flashes once
//     - Received data is sent via SPI. This can be
//       displayed e.g. with the IQRF IDE Terminal (See IQRF IDE Help).
//   - The length (DLEN) of the packet actually received is
//     automatically set within the RFRXpacket() function.
