https://devzone.nordicsemi.com/f/nordic-q-a/66787/how-to-automatically-connect-bluetooth-when-launching-a-custom-appHello I am developing a device that uses BLE. User will connect bluetooth directly the first time they launch a custom app, and they will try to connect automatically the next time they run it. (until the user manually disconnects the Bluetooth.)
