/*******************************************************************************
    The "Basic RF" library contains simple functions for packet transmission and
    reception with the CC2520 radio chip. The intention of this library is mainly
    to demonstrate how the CC2520 is operated, and not to provide a complete and
    fully-functional packet protocol. The protocol uses 802.15.4 MAC compliant data
    and acknowledgment packets, however it contains only a small subset of  the
    802.15.4 standard:
    - Association, scanning nor beacons are not implemented
    - No defined coordinator/device roles (peer-to-peer, all nodes are equal)
    - Waits for the channel to become ready, but does not check CCA twice
    (802.15.4 CSMA-CA)
    - Does not retransmit packets

    INSTRUCTIONS:
    Startup:
    1. Create a basicRfCfg_t structure, and initialize the members:
    2. Call basicRfInit() to initialize the packet protocol.

    Transmission:
    1. Create a buffer with the payload to send
    2. Call basicRfSendPacket()

    Reception:
    1. Check if a packet is ready to be received by highger layer with
    basicRfPacketIsReady()
    2. Call basicRfReceive() to receive the packet by higher layer

    FRAME FORMATS:
    Data packets (without security):
    [Preambles (4)][SFD (1)][Length (1)][Frame control field (2)]
    [Sequence number (1)][PAN ID (2)][Dest. address (2)][Source address (2)]
    [Payload (Length - 2+1+2+2+2)][Frame check sequence (2)]

    Acknowledgment packets:
    [Preambles (4)][SFD (1)][Length = 5 (1)][Frame control field (2)]
    [Sequence number (1)][Frame check sequence (2)]
