•
AddrComp allows conditioning the packet reception to a predefined peer device address. Node address and broadcast
address can be set with the SetPacketAdrs( )command. If the address comparison fails then the packet reception is
aborted and the adrsErr flag is set.

•
PayloadLen defines the length of the payload in Bytes,
•
CrcType defines the packet CRC:

CrcType
0x01
0x00
0x02
0x04
0x06
The CRC can be fully configured and the polynomial used, as well as the initial values can be entered directly through the
command SetGfskCrcParams( ) .
• Whitening allows to enable the whitening on the RF packet
