Using the nRF52840 with NCS v2.6.1, I want to put the device into a low-power sleep state during idle time. Before sleeping, I configured a GPIO interrupt as the wake-up source, and then I call sys_poweroff(); to enter deep sleep mode. The issue I'm facing is that while the device can enter deep sleep, it cannot wake up from it; I can only reset the device to regain functionality.
