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 via the following ways.
Hardware:
W_DISABLE# is pulled up by default. Driving it low will let the module enter airplane mode.
Software:
AT+CFUN=<fun>
provides choices of the functionality level through setting
<fun>
into 0, 1 or 4.
AT+CFUN=0:
Minimum functionality mode. Both RF and (U)SIM functions are disabled.
AT+CFUN=1:
Full functionality mode (by default).
AT+CFUN=4:
Airplane mode (RF function is disabled).
3.3. Power Saving Mode (PSM)
BG950A-GL/BG951A-GL module minimizes its power consumption through 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, BG950A-GL/BG951A-GL module in PSM cannot
immediately respond to users’ requests.
When the module wants to use the PSM, it shall request an Active Time value during every Attach and
During e-I-DRX, it is recommended to use the main UART interface for data communication, as the use
of USB interface
*
will increase power consumption.
1. Airplane mode control via W_DISABLE# is disabled in firmware by default. It can be enabled by
AT+QCFG="airplanecontrol"
. For more details of the command, see
document [2].
2. For BG950A-GL, the execution of
AT+CFUN
will affect GNSS function. Since the module does not
support concurrent operation of WWAN and GNSS, the GNSS function can be used when
<fun>
=0
or 4, but cannot be used when
<fun>
=1.
3. For BG951A-GL, the execution of
AT+CFUN
will not affect GNSS function.
