LPWA Module Series
BG95 Series Hardware Design
BG95_Series_Hardware_Design 35 / 106
Hardware:
W_DISABLE#* is pulled up by default. Driving it low makes 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. See document [2] for the
details about the command.
2. The execution of AT+CFUN command will not affect GNSS function.
3. “*” means under development.
3.4.2. Power Saving Mode (PSM)
BG95 module can enter PSM to reduce its power consumption. 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. So BG95 in PSM cannot immediately respond users’ requests.
When the module wants to use the PSM it shall request an Active Time value during every Attach and
TAU procedures. If the network supports PSM and accepts that the module uses PSM, it will confirm the
usage of PSM by allocating an Active Time value to the module. If the module wants to change the Active
Time value, e.g. when the conditions are changed in the module, the module consequently requests the
value it wants in the TAU procedure.
If PSM is supported by the network, then it can be enabled via AT+CPSMS command.
Either of the following methods can wake up the module from PSM:
 Wake up the module from PSM through a rising edge on PON_TRIG. (Recommended)
 Wake up the module by driving PWRKEY low.
 The module is woken up automatically when the T3412_Ext timer expires.
See document [2] for details about AT+CPSMS command.
