I need to run this by our SoftDevice team. In the meantime. Is there some way for me to reproduce what you are seeing? Do you have applications that can run on a set of nRF54L15 DKs that will be able to reproduce the asserts that you are seeing?</p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
