3.2.3 Reset Function
MODULE can be reset by pulling the RESET pin down to ground.
This function is only used as an emergency reset, when AT command “AT+CPOF” and the PWRKEY
pin all have lost efficacy.
The RESET pin has been pulled up with a 40KΩ resistor to 1.8V internally, so it does not need to be pulled
up externally. It is strongly recommended to put a100nF capacitor and an ESD protection diode close to the
RESET pin. Please refer to the following figure for the recommended reference circuit.
