BT (Guard Time Before) Command
CC (Command Sequence Character) Command
CD (GPO2 Configuration) Command
CF (Number Base) Command
<AT Command Mode Options> BT Command is
used to set the DI pin silence time that must pre-
cede the command sequence character (CC com-
mand) of the AT Command Mode sequence.
Refer to the ‘AT Command Mode’ section [p17] for
more information regarding the AT Command
Mode Sequence.
<AT Command Mode Options> The CC command
is used to set/read the ASCII character used
between guard times of the AT Command Mode
Sequence (BT + CC + AT). This sequence enters
the module into AT Command Mode so that data
entering the module (from the host) is recognized
as commands instead of payload.
Refer to the ‘AT Command Mode’ section [p17] for
more information regarding the AT Command
Mode Sequence.
<Serial Interfacing> CD Command is used to
select/read the behavior of the GPO2 line (pin 3).
<Command Mode Options> CF command is used
to set/read the command formatting setting.
The following commands are always entered and
read in hex, no matter the CF setting:
