3.4.3. Restart module using the PWRKEY pin
Customer’s application can restart the module by driving the PWRKEY to a low level voltage for
certain time, which is similar to the way to turn on the module. Before restarting the module, at least
500ms should be delayed after detecting the low level of STATUS. The restart scenario is illustrated
as the following figure.

The module can also be restarted by the PWRKEY after emergency shutdown.
