It is suggested that you should switch off power supply for module in abnormal state, and then switch on
power to restart module.
3.6.4. Monitor the Power Supply
The command AT+CBC can be used to monitor the VBAT_BB voltage value displayed in millivolt. For
more details, please refer to document [1].

When UG96 is in power down mode, it can be turned on to normal mode by driving the PWRKEY pin to a
low level at least 100ms. It is recommended to use an open drain/collector driver to control the PWRKEY.
The STATUS pin output a high level after UG96 is turned on. A simple reference circuit is illustrated in the
following figure.
