Start Delimiter
* Length [Bytes] = API Identifier + Frame ID + AT Command + Parameter Value
** “M” value was arbitrarily selected.
Identifies the UART data frame for the host to
correlate with a subsequent ACK (acknowledgement).
If set to ‘0’, no response is sent.

API Identifier Value: 0x08
Allows for module parameter registers to be queried or set.

Figure 6‐7.
A string parameter used with the NI (Node Identifier), ND (Node Discover) and DH (Destination
Address High) command is terminated with a 0x00 character.
API Identifier Value: 0x09
This API type allows module parameters to be queried or set. In contrast to the “AT Command”
API type, new parameter values are queued and not applied until either the “AT Command” (0x08)
API type or the AC (Apply Changes) command is issued. Register queries (reading parameter
values) are returned immediately.
