Command descriptions for the XBee/XBee-PRO RF Module
XBee / XBee-PRO RF Modules 802.15.4 Product Manual 59
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 parameter
values to non-volatile memory, but the module still operates according to previously saved values
until the module is re-booted or the CN (Exit AT Command Mode) command is issued.
Refer to AT Command - queue parameter value on page 92 for more information.
AI (Association Indication) command
<Networking {Association}> The AI command is used to indicate occurrences of errors during the last
association request.
