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
message. Some commands will send back multiple frames (for example, the ND (Node Discover)
command).

address is unknown.
Command Options (byte 16)
0x02 - Apply changes on remote. (If
not set, AC command must be sent
before changes will take effect.)

of the requested register
Command Name (bytes
17-18)
Name of the
command
Command Data (byte 19-n)
If present, indicates the requested
parameter value to set the given
register. If no characters present,
the register is queried.
