LPWA Module Series
BG95 Hardware Design
BG95_Hardware_Design 33 / 88
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 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 low will let the module enter airplane mode.
Software:
AT+CFUN=<fun> 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.
1. Airplane mode control via W_DISABLE# is disabled in firmware by default. It can be enabled by
AT+QCFG="airplanecontrol" command which is still under development. Details about the
command will be provided in document [2].
Mode
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 OFF
Mode
In this mode, the power management unit shuts down the power supply. The software
is not active. The serial interfaces are not accessible. But the operating voltage
(connected to VBAT_RF and VBAT_BB) remains applied.
Power Saving
Mode
(PSM)
The module may enter PSM to reduce 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.
