Airplane
Mode
AT+CFUN
command or W_DISABLE#* pin can set the module into airplane mode. In this
case, RF function will be invalid.
Minimum
Functionality
Mode
AT+CFUN
command can set the module into a minimum functionality mode without
removing the power supply. In this case, both RF function and (U)SIM card will be invalid.
Sleep Mode
In this mode, the current consumption of the module will be reduced to a lower level.
During this mode, the module can still receive paging message, SMS and TCP/UDP data
from the network normally.
Power Saving
Mode
(PSM)
BG96 module may enter into Power Saving Mode for reducing its power consumption.
PSM 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.
Power OFF
Mode
In this mode, the power management unit shuts down the power supply. Software is not
active. The serial interfaces are not accessible. But operating voltage (connected to
VBAT_RF and VBAT_BB) remains applied.
1. During e-I-DRX, it is recommended to use UART interface for data communication, as the use of USB
interface will increase power consumption.
2.
“*” means under development.
3.4. Power Saving
3.4.1. Airplane Mode
When the module enters into airplane mode, the RF function does not work, 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 to low level will let the module enter into airplane mode.
Software:
AT+CFUN=<fun>
command provides choice 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.
