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.
Example. The above example sends a remote command to change the broadcast hops register
on a remote device to 1 (broadcasts 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.
Frame Fields Offset Example Description
Start Delimiter 0 0x7E
Length
MSB 1 0x00
Number of bytes between the length

Frame-specific
Data
Frame Type 3 0x17
Frame ID 4 0x01
Identifies the UART data frame for
the host to correlate with a
subsequent ACK (acknowledgement).
If set to 0, no response is sent.
