XBee®/XBee‐PRO® ZB SMT RF Modules
Remote AT Command Request
Frame Type: 0x17
Used to query or set module parameters on a remote device. For parameter changes on the remote device to
take effect, changes must be applied, either by setting the apply changes options bit, or by sending an AC
command to the remote.

Frame-specific Data Frame Type
Frame ID
Identifies the serial port data frame for the host to
correlate with a subsequent ACK (acknowledgement). If
set to 0, no response is sent.
4 0x01
MSB 5 0x00
6 0x13
Set to the 64-bit address of the destination device. The
following addresses are also supported:
0x0000000000000000 - Reserved 64-bit address for the
coordinator
7 0xA2

8 0x00

MSB 13 0xFF
Set to the 16-bit address of the destination device, if
known. Set to 0xFFFE if the address is unknown, or if
sending a broadcast.

Bitfield to enable various remote command options.
Supported values include:
0x01 - Disable ACK
0x02 - Apply changes on remote. (If
not set, AC command must be sent
before changes will take effect.)
0x40 - Use the extended transmission timeout for this
destination.

Setting the extended timeout bit causes the stack to set
the extended transmission timeout for the destination
address (see chapter 4).
All unused and unsupported bits must be set to 0.

Name of the
command
AT Command
If present, indicates the requested
parameter value to set the given
register. If no characters present,
the register is queried.
Command Parameter
18 0x01
19 0xF5
Checksum
0xFF - the 8 bit sum of bytes from offset 3 to this byte.
Example: Send a remote command to change the broadcast hops register on a remote device to 1 (broad-
casts go to 1-hop neighbors only), and apply changes so the new configuration value immediately takes
effect. In this example, the 64-bit address of the remote is 0x0013A200 40401122, and the destination 16-
bit address is unknown.
