1. Please ensure that there is no large capacitance with the max value exceeding 10nF on PWRKEY
and RESET_N pins.
2. RESET_N only resets the internal baseband chip of the module and does not reset the power
management chip.
3. It is recommended to use RESET_N only when failing to turn off the module by AT+QPOWD
command or PWRKEY pin.
