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.
take effect, changes must be applied, either by setting the apply changes options bit, or by sending an AC
command to the remote.
Example: Send 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, and the destination 16-bit address is unknown.
