It can caused the module logoff from the network and allow the software to enter into a secure 
state and save data before completely disconnect the power supply. 
 
Before the completion of the switching off procedure the module will send out result code: 

NORMAL POWER DOWN 

 

After this moment, the AT commands can’t be executed. The module enters the POWER DOWN 
mode, only the RTC is still active. POWER DOWN can also be indicated by VDD_EXT pin, 
which is a low level voltage in this mode.

3.4.2.2 Turn off module using AT command 

You can use an AT command “AT+QPOWD=1” to turn off the module. This command will let 
the module to log off from the network and allow the software to enter into a secure state and save 
data before completely disconnecting the power supply. 
 
Before the completion of the switching off procedure the module will send out result code: 

NORMAL POWER DOWN 

 
After this moment, the AT commands can’t be executed. The module enters the POWER DOWN 
mode, only the RTC is still active. POWER DOWN can also be indicated by VDD_EXT pin, 
which is a low level voltage in this mode. 
 
Please refer to

 for detail about the AT command of “AT+QPOWD”.   

3.4.2.3 Over-voltage or under-voltage automatic shutdown 

The module will constantly monitor the voltage applied on the VBAT, if the voltage
