3.2.3 Reset Function
SIM7000 can be reset by pulling the RESET pin to ground.
Note: This function is only used as an emergency reset. The RESET pin will be ineffectiveness
in the power off mode.
The RESET pin has been pulled up to 1.8V with a 40KΩ resistor 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.
