Questions about AT%XVBAT

[xinjiang]

I use AT%XVBAT command as the power query of the device.Now when the voltage is inquired, the return value jumps and the measurement is inaccurate.During this period, there was no large current. May I ask what situation will cause the modem voltage return value to be abnormal

Hi, 

The AT%XVBAT documentation states: 
When the modem is active (either LTE communication or GPS receiver), the %XVBAT command returns the latest voltage measured automatically during modem wakeup or reception. The voltage measured during transmission is not reported. During modem inactivity, the modem measures battery voltage when the %XVBAT command is received.

Kind regards, 
Øyvind
