: 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. For more details about the command, please refer to
document [2]
.
2. The execution of
AT+CFUN
command will not affect GNSS function.
3.4.2. Power Saving Mode (PSM)
BG96 module can enter PSM for reducing 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 BG96 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 will wake up the module from PSM:
Drive PWRKEY pin to low level will wake up the module.
When the T3412_Ext timer expires, the module will be automatically woken up.
Please refer to
document [2]
for details about
AT+CPSMS
command.
3.4.3. Extended Idle Mode DRX (e-I-DRX)
The module (UE) and the network may negotiate over non-access stratum signalling the use of e-I-DRX
for reducing its power consumption, while being available for mobile terminating data and/or network
originated procedures within a certain delay dependent on the DRX cycle value.
Applications that want to use e-I-DRX need to consider specific handling of mobile terminating services or
data transfers, and in particular they need to consider the delay tolerance of mobile terminated data.
