set the Module
RES
ET_N is used to reset the module. Due to platform limitations, the chipset has integrated the reset
function into PWRKEY, and RESET_N connects directly to PWRKEY inside the module.
The module can be reset by driving RESET_N low for 2–3.8 s.
Table 9: Pin Definition of RESET_N
The reset scenario is illustrated in the following figure.

The recommended circuit is similar to the PWRKEY control circuit. An open drain/collector driver or button
can be used to control the RESET_N pin.
