Hi Simonr Thank you very much for your reply I connected my DK board to my laptop. At this time, the laptop did not have a screen, but after 2-3 seconds of connecting, a suspend occurred /** * Copyright (c) 2017 - 2021, Nordic Semiconductor ASA * * All rights reserved. * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * * 1.
