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 operatingmode on the radio interface: it ranges from 0.5s in TALK / DATA mode up to 50s when TC45 is
in IDLE mode or Limited Service (deregistered).
