Command Description

The exec command allows to monitor the supply (or battery) voltage of the module measured on pin BATT+. The reference point for measuring the voltage are the test points BATT+ and GND on the bottom of the module. Refer to [1] for information on the module's test points.

The displayed value is constant over the measurement period. The duration of the measurement period depends on the operating mode on the radio interface: it ranges from 0.5s in TALK / DATA mode up to 50s when MC55 is in IDLE mode or Limited Service (deregistered).
