Turn Off Module; Turn Off Module Through Pwrkey; Turn Off Module Through At Command - Quectel BG772A-GL Hardware Design

NOTE
Ensure that VBAT is stable before pulling down PWRKEY pin and keep the interval no less than 30 ms.

3.6.3. Turn off Module

Either of the following methods can be used to turn off the module normally:
Turn off the module through PWRKEY.

Turn off the module through AT+QPOWD.


3.6.3.1.Turn off Module through PWRKEY

Drive the PWRKEY pin low for 650–1500 ms and then releasing it, the module will execute power-down
procedure.
The power-down timing is illustrated in the following figure.

3.6.3.2.Turn off Module through AT Command

It is also a safe way to use AT+QPOWD to turn off the module, which is similar to turning off the module
with PWRKEY.
See document [4] for details about AT+QPOWD.
