AT Command Response
API Identifier Value: 0x88
Response to previous command.
In response to an AT Command message, the module will send an AT Command Response mes-
sage. Some commands will send back multiple frames (for example, the ND (Node Discover) and
AS (Active Scan) commands). These commands will end by sending a frame with a status of
ATCMD_OK and no cmdData.

TX (Transmit) Request: 64-bit address
API Identifier Value: 0x00
A TX Request message will cause the module to send RF Data as an RF Packet.

TX (Transmit) Request: 16-bit address
API Identifier Value: 0x01
A TX Request message will cause the module to send RF Data as an RF Packet.

Frame ID (Byte 5 )
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 (Bytes 6-7)
Command Name - Two
ASCII characters that
identify the AT Command.

0 = OK
1 = ERROR

Frame ID (Byte 5)
Identifies the UART data frame for the host to
correlate with a subsequent ACK (acknowledgement).
Setting Frame ID to 0' will disable response frame.
Destination Address (Bytes 6-13)
MSB first, LSB last.

0x000000000000FFFF
Options (Byte 14)
0x01 = Disable ACK
0x04 = Send packet with Broadcast Pan ID
All other bits must be set to 0.
