NOTE
In e-I-DRX mode, it is recommended to use the main UART interface for data communication, as the
use of USB interface will increase power consumption.
3.2. Airplane Mode
When the module enters airplane mode, the RF function will be disabled, and all AT commands
correlative with RF function will be inaccessible. This mode can be set as follows:
Hardware:
W_DISABLE# is pulled up by default. Driving it low will make the module enter airplane mode.
Software:
AT+CFUN=<fun> provides functionality level choices by setting <fun> to 0, 1 or 4.
AT+CFUN=0: Minimum functionality. Both RF and (U)SIM functions are disabled.

AT+CFUN=1: Full functionality (default).

AT+CFUN=4: Airplane mode (RF function is disabled).

NOTE
1. Airplane mode control via W_DISABLE# is disabled in firmware by default. It can be enabled with
AT+QCFG="airplanecontrol". For more details of the command, see document [2].
2. On BG950A-GL/BG953A-GL/BG955A-GL, the execution of AT+CFUN will affect the GNSS
function. Since the module does not support concurrent operation of LTE and GNSS, the GNSS
function can be used when <fun>=0 or 4, but cannot be used when <fun>=1.
3. On BG951A-GL, the execution of AT+CFUN will not affect the GNSS function.
3.3. Power Saving Mode (PSM)
The module minimizes its power consumption by entering PSM. The mode is similar to power-off, but the
module remains registered on the network and there is no need to re-attach or re-establish PDN
connections. Therefore, in PSM the module cannot immediately respond to user requests.
When the module wants to use PSM, it shall request an Active Time value during every Attach and TAU
procedure. If the network supports PSM use, it will allocate an Active Time value to the module to confirm
