17.3 AT^SBV Battery/Supply Voltage
AT^SBV 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 measurement period ranges
from 0.5s in TALK / DATA mode up to 50s when BGS2T is in IDLE mode or Limited Service (deregistered). The
displayed value is averaged over the last measuring period before the AT^SBV command was executed.
The measurement is related to the reference points of BATT+ and GND. For details on the reference points
please refer to the Hardware Interface Description [2].
