I have tried to use sd_app_evt_wait() to sleep cpu, and use gpiote interrupt to wake up cpu from sleep. However, gpiote interrupt cannot wake up cpu. When I use __WFE(), gpiote interrupt can wake up cpu. And even if I use sd_app_evt_wait(), log print…

While analyzing the current consumption of my nRF52832 Dev Kit I noticed that the system on low power current was significantly higher than expected. To further investigate this I loaded a small program that only has a call to __WFE() in a while loop…
