2.6.2.2 Turn off Module with 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 with PWRKEY.
Please refer to document [2] for details about AT+QPOWD command.
2.7 Reset the Module
RESET_N is used to reset the module. Due to platform limitations, the chipset has integrated the reset
function into PWRKEY, and RESET_N is connected directly to PWRKEY inside the module.
The module can be reset by driving RESET_N low for 2–3.8 s.
