LPWA Module Series
BG96 Hardware Design
BG96_Hardware_Design 25 / 79
During e-I-DRX, it is recommended to use UART interface for data communication, as the use of USB
interface will increase power consumption.
3.4. Power Saving
3.4.1. Airplane Mode
When the module enters 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 airplane mode.
Software:
AT+CFUN=<fun>
command provides choice of the functionality level, through specifying
<fun>
as 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).
Extended Idle
Mode DRX
(e-I-DRX)
BG96 module and the network may negotiate over non-access stratum signaling the
use of e-I-DRX for reducing power consumption, while being available for mobile
terminating data and/or network originated procedures within a certain delay dependent
on the DRX cycle value.
Airplane
Mode
AT+CFUN=4
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=0
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 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.
