May I ask what situation will cause the modem voltage returnen-USTelligent Community 13Thu, 25 Feb 2021 12:21:11 GMThttps://devzone.nordicsemi.com/thread/296240?ContentTypeID=1Thu, 25 Feb 2021 12:21:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28f822aa-e4d2-4ffa-9e2d-cbe30642b46a&#216;yvind<p>Hi,&nbsp;</p> <p>The <a href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/xvbat.html">AT%XVBAT documentation states</a>:&nbsp;<br /><em>When the modem is active (either LTE communication or GPS receiver), the&nbsp;<span>%XVBAT</span>&nbsp;command returns the latest voltage measured automatically during modem wakeup or reception.
