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.
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.
Note
Once you issue a
WR
command, do not send any additional characters to the device until after
you receive the
OK
response.
