HI, I'm using sd_app_evt_wait() for getting back to sleep mode between advertisings. I noticed that when I change the voltage in a small interval mode (40 ms between advs) the system gets an event, exit sd_app_evt_wait() and going back to consume high current. I'm not sure why it happens. It's much more rare to fail the system when it's on big intervals (every 2 seconds for example), but still, if I change the voltage in once (for example from 3.0V to 2.7 V) it will exit "wait for event" mode almost every time in 40ms intervals and sometimes in 2 sec intervals.
My problem begins when I'm trying to connect my card to a battery, then I see similar occurrence of getting out from "wait for event mode".
Anyone knows what the problem may be?
Thanks.
