3.7.2.2. Turn off Module Using AT Command
It is also a safe way to use
AT+QPOWD
command to turn off the module, which is similar to turning off the
module via PWRKEY Pin.
Please refer to
document [1]
for details about

works normally. Only after the module is shut down by PWRKEY or AT command, the power supply
can be cut off.

a low level voltage for 250ms~600ms.
