Parameter range
2 - 0x1770 (x 100 ms)
Default
0x64 (10 seconds)
CN (Exit Command mode)
Makes the device exit Command mode, applying changes.
Parameter range
N/A
Default
N/A
AC (Apply Changes)
Immediately applies new settings without exiting Command mode.
Applying changes means that the device is re-initialized 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 the CN (Exit AT Command Mode) or AC commands are issued. For more
information, see AT Command - Queue Parameter Value frame - 0x09 on page 106.
Parameter range
N/A
Default
N/A
GT (Guard Times)
Set the required period of silence before and after the command sequence characters of the
Command mode sequence (GT + CC + GT). The period of silence prevents inadvertently entering
Command mode.
Parameter range
2 - 0xCE4 (x 1 ms)
Default
CC (Command Sequence Character)
The character value you use to enter Command mode.
The default value (0x2B) is the ASCII code for the plus (+) character. You must enter it three times
within the guard time to enter Command mode from Idle mode. To enter Command mode, there is
also a required period of silence before and after the command sequence characters of the Command
mode sequence (GT + CC + GT). The period of silence prevents inadvertently entering Command
mode.
