Hi, i'm trying to read an i2c sensor on interrupt. Doing it directly in the interrupt is apparantly bad, so io tried using app_sched_event_put, but that just crashes inside...
Hi,
I'm debugging a small app that is using the LPCOMP to trigger an interrupt when the BLE device is turned off. We have a capacitor to maintain alive the nRF for a while...
