XBee/XBee‐PRO ZigBee OEM RF Modules v1.x1x [2007.06.01]
Identifies the UART data fram e for the host to
correlate with a subsequent ACK (acknowledgem ent).
Setting Fram e ID to ‘0' will disable response frame.
Identifies the UART data frame being reported.
Note: If Frame ID = 0 in AT Command Mode,
no AT Command Response will be given.
AT Command Response
ZigBee Transmit Request
Frame ID (Byte 5)
API Identifier Value: 0x88
Response to previous command.
In response to an AT Command message, the module will send an AT Command Response
message. Some commands will send back multiple frames (for example, the ND (Node Discover)
command). These commands will end by sending a frame with a status of ATCMD_OK and no
cmdData.

API Identifier Value: 0x10
A TX Request message will cause the module to send RF Data as an RF Packet.TX Packet Frames
