AT commands

Command mode options

The following commands are Command mode option commands.

CC (Command Sequence Character)

The character value the device uses 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. 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.
Parameter range
0 - 0xFF
Default
0x2B (the ASCII plus character: +)

CT (Command Mode Timeout)

Sets or displays the Command mode timeout parameter. If a device does not receive any valid
commands within this time period, it returns to Idle mode from Command mode.
Parameter range
2 - 0x1770 (x 100 ms)
Default
0x64 (10 seconds)

CN (Exit Command mode)

Immediately exits Command Mode and applies pending changes.
Note Whether Command mode is exited using the CN command or by CT timing out, changes are
applied upon exit.
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
0x2 - 0x6D3 (x 1 ms)
