XBee®/XBee‐PRO® ZB SMT RF Modules
ZigBee Explicit Rx Indicator
Frame Type:0x91
When the modem receives a ZigBee RF packet it is sent out the serial port using this message type (when
AO=1).
Frame Fields

Profile ID the packet was
addressed to.
0x01 – Packet Acknowledged
0x02 – Packet was a broadcast packet
0x20 - Packet encrypted with APS encryption
0x40 - Packet was sent from an end device (if known)
Receive Options
20 0x02
21 0x52
22 0x78
23 0x44

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 broadcast data transmission to a remote device with payload "RxData". Suppose the transmission
was sent with source and destination endpoints of 0xE0, cluster ID=0x2211, and profile ID=0xC105. If
AO=1 on the receiving device, it would send the above frame out its serial port.
