How to let nordic keep in a sleep-awake cyclehttps://devzone.nordicsemi.com/f/nordic-q-a/101485/how-to-let-nordic-keep-in-a-sleep-awake-cycleHi There, I am using nrf52840 ks. I want to make the Nordic boards sleep (in a low power mode, but everything is lost) and awake (initialize again) by pins controlled by another boards. How can I do it?
