Now I want CPU to go to sleep mode with sd_app_evt_wait(), and CPU to be waken up via Button then receive uart data via GPIOTE and GPIO. The CPU is woken up on button press and the handleren-USTelligent Community 13Fri, 13 Sep 2019 12:51:40 GMThttps://devzone.nordicsemi.com/thread/209627?ContentTypeID=1Fri, 13 Sep 2019 12:51:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:97035781-4b3e-459c-ba28-3baa104f5503Jared<p>Hi,</p> <p>Could you share your project?</p> <p>Best regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/209592?ContentTypeID=1Fri, 13 Sep 2019 10:42:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c330963c-66cd-4fc3-94f5-1513af128accshah_shah<p>Is this handler executes in interrupts context?
