GV300 @Track Air Interface Protocol
3.2.8. External Power Supply Monitoring
The command AT+GTEPS is used to configure the parameters of external power supply
monitoring. The device will measure and monitor the voltage of the external power supply. If the
voltage of the external power supply matches the predefined alarm condition, the device will
report an alarm message +RESP:GTEPS to the backend server to notify the status of the external
power supply.
To make sure this function works in all situations, please switch on the internal backup battery in
case that the voltage of the external power supply may drop very low.
