AT+QCFG="vbatt" Voltage Detection
AT+QCFG="vbatt" can enable voltage detection and set corresponding parameters.
About Voltage Detection:
When the voltage is lower than the lowest voltage limit, the module will output:
+QIND: "vbatt",-2
If it does not come back to a degree greater than the lowest voltage limit within 2 seconds, the module will
be turned off automatically.
When the voltage is greater than the lowest voltage limit, but lower than low voltage warning limit, the
module will output:
+QIND: "vbatt",-1
When the voltage is greater than the highest voltage limit, the module will output:
+QIND: "vbatt",2
If it does not come back to a degree lower than highest voltage limit within 2 seconds, the module will be
turned off automatically.
