3.3. Airplane Mode
When the module enters into airplane mode, the RF function will be disabled, and all AT commands
related to it will be inaccessible. This mode can be set via the following ways.
Hardware:
The W_DISABLE# pin is pulled up by default. Its control function for airplane mode is disabled by default,
and
AT+QCFG=“airplanecontrol”,1
can be used to enable the function. Driving the pin to low level can
make the module enter airplane mode.
Software:
AT+CFUN=<fun>
command provides choices of the functionality level through setting
<fun>
into 0, 1
or 4.
⚫
AT+CFUN=0:
Minimum functionality mode (Both (U)SIM and RF functions are disabled.).
⚫
AT+CFUN=1:
Full functionality mode (by default).
⚫
AT+CFUN=4:
Airplane mode (RF function is disabled.).
Please pay attention to the level match shown in dotted line between the module and the host.
