Identifies the UART data frame for the host to
correlate with a subsequent ACK (acknowledgement).
If set to ‘0’, no response is sent.

If set to ‘0’, no response is requested.
AT Command
AT Command - Queue Parameter Value
API Identifier Value: 0x08
The “AT Command” API type allows for module parameters to be queried or set. When using this
command ID, new parameter values are applied immediately. This includes any register set with
the “AT Command - Queue Parameter Value” (0x09) API type.

Figure 3‐07. Example: API frames when modifying the DL parameter value of the module.
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.
