Siemens MC55 AT manual Atsbv Battery/Supply Voltage, Atsbv=?, SBV value

18.4AT^SBV Battery/Supply Voltage

The AT^SBV execute command allows to monitor the supply (or battery) voltage of the module. The voltage is continuously measured at intervals depending on the operating mode of the RF interface. The duration of a mea- surement period ranges from 0.5s in TALK / DATA mode up to 50s when MC55 is in IDLE mode or Limited Ser- vice (deregistered). The displayed value is averaged over the last measuring period before the AT^SBV command was executed.

The measurement is related to the test points of BATT+ and GND, both accessible on the bottom of the module. Refer to [1] for information on the module's test points.
