The 

 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 AC75 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 reference points of BATT+ and GND, both accessible on a capacitor located

close to the module's board-to-board connector. For details please refer to the Hardware Interface Description
