XBee®/XBee‐PRO® ZB SMT RF Modules
ZigBee Receive Packet
Frame Type: (0x90)
When the module receives an RF packet, it is sent out the serial port using this message type.

Received Data
Received RF data
Checksum
0xFF - the 8 bit sum of bytes from offset 3 to this byte.
Example: Suppose a device with a 64-bit address of 0x0013A200 40522BAA, and 16-bit address 0x7D84
sends a unicast data transmission to a remote device with payload "RxData". If AO=0 on the receiving
device, it would send the above example frame out its serial port.
