https://devzone.nordicsemi.com/f/nordic-q-a/58009/wake-up-from-system-offHi, I am completely new to this technology. I am currently programming a custom board equipped with an nRF52832 based on the ble_app_uart example in the SDK 15.2 and is connected to a LIS2DH12 accelerometer. Everything is working correctly.
