AT^SBV Battery/Supply Voltage
The
execute command allows to monitor the supply (or battery) voltage of the module. The voltage is
AT^SBV
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
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.
