AC (Apply Changes) Command
<AT Command Mode Options> The AC command
is used to explicitly apply changes to module
parameter values. ‘Applying changes’ means that
the module is re-initialized based on changes
made to its parameter values. Once changes are applied, the module immediately operates
according to the new parameter values.
This behavior is in contrast to issuing the WR (Write) command. The WR command saves parame-
ter values to non-volatile memory, but the module still operates according to previously saved val-
ues until the module is re-booted or the CN (Exit AT Command Mode) command is issued.
Refer to the “AT Command - Queue Parameter Value” API type for more information.
AI (Association Indication) Command
<Networking {Association}> The AI command is
used to indicate occurrences of errors during the
last association request.
Use the table below to determine meaning of the
returned values.
Returned Value (Hex) Association Indication
0x00 Successful Completion - Coordinator successfully started or End Device association complete
0x01 Active Scan Timeout
0x02 Active Scan found no PANs
0x03 Active Scan found PAN, but the Coordinator Allow Association bit is not set
0x04 Active Scan found PAN, but Coordinator and End Device are not configured to support beacons
0x05 Active Scan found PAN, but Coordinator ID (PAN ID) value does not match the ID of the End Device
0x06 Active Scan found PAN, but Coordinator CH (Channel) value does not match the CH of the End Device
