3.7.3.2. Turn off Module Using API Interface

It is also a safe way to use API interface to turn off the module, which is similar to turning off the module
via PWRKEY Pin.
See document [2] for details about API function.
NOTES
1. To avoid damaging the internal flash, please do not switch off the power supply when the module
works normally. Only after the module is shut down by PWRKEY or API interface, the power supply
can be cut off.
2. When turn off module with API, please keep PWRKEY at high level after the execution of power off
command. Otherwise the module will be turned on again after successfully turn-off.

3.8. Reset the Module

RESET can be used to reset the module. The module can be reset by driving RESET low for at least
370 ms. As the RESET pin is sensitive to interference, the routing trace is recommended to be as short as
possible and totally ground shielded.
