Special commands
The following commands are special commands.
AC (Apply Changes)
Immediately applies new settings without exiting Command mode.
Applying changes means that the device re-initializes based on changes made to its parameter values.
Once changes are applied, the device 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 device still operates according to previously saved values until
the device is rebooted or you issue the CN (Exit AT Command Mode) or AC commands.
Parameter range
N/A
Default
N/A
FR (Force Reset)
Resets the device. The device responds immediately with an OK and performs a reset 100 ms later.
If you issue FR while the device is in Command Mode, the reset effectively exits Command mode.
Note We recommend entering Airplane mode before resetting or rebooting the device to allow the
cellular module to detach from the network.
Parameter range
N/A
Default
N/A
RE (Restore Defaults)
Restore device parameters to factory defaults.
The RE command does not write restored values to non-volatile (persistent) memory. Issue the WR
(Write) command after issuing the RE command to save restored parameter values to non-volatile
memory.
Parameter range
N/A
Default
N/A
WR (Write)
Writes parameter values to non-volatile memory so that parameter modifications persist through
subsequent resets.
