Does the log say anything?</p> <p>Is it possible for me to reproduce it on an nRF52832 DK? If so, can you send the project that you used when you got this issue?</p> <p></p> <p>Was there something particular that you added right before this issue started appearing?</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
