3 TX and RX Settings Exported with the Advanced Commands

All PHYs that are, by default, exported/imported with the CMD_PROP_TX_ADV or CMD_PROP_RX_ADV commands use a packet format specified by IEEE 802.15.4g. This format is shown in Figure 3-1.

Advanced Packet FormatFigure 3-1 Advanced Packet Format

The sync word (0x55904E) is followed by a 2 bytes long header (PHR) containing the following fields:

PHR[15] MS: Mode Switch (always set to 0)

PHR[14:13] Reserved (Don't care)

PHR[12] FCS: FCS Type (0: 4 bytes CRC, 1: 2 bytes CRC)

PHR[11] DW: Data whitening (0: Disable, 1: Enable)

PHR[10:0] Length

The length field should include the CRC bytes (2 or 4 bytes depending on the FCS field in the PHR), meaning that if you want to transmit the 3 bytes long payload used in the previous example, the length in the header should be 5 or 7. If you for example want to use a 4 bytes long CRC (FCS = 0) plus whitening (DW = 1), the header would be 0x0807.
