19.4 <strong>AT</strong>^SBV<br />

19.4 <strong>AT</strong>^SBV Battery/Supply Voltage<br />

The <strong>AT</strong>^SBV execute command allows to monitor the supply (or battery) voltage of the module. The voltage is<br />

continuously measured at intervals depending on the operating mode of the RF interface. The duration of a measurement<br />

period ranges from 0.5s in TALK / D<strong>AT</strong>A mode up to 50s when <strong>TC63i</strong> is in IDLE mode or Limited Service<br />

(deregistered). The displayed value is averaged over the last measuring period before the <strong>AT</strong>^SBV<br />

command was executed.<br />

The measurement is related to the reference points of B<strong>AT</strong>T+ and GND. For details on the reference points<br />

please refer to the Hardware Interface Description [2].<br />
