If you didn&#39;t already try on a nRF54L15 DK, can please try on one? It would allow us to be more confident that this is not an application problem.</p> <p>If it works fine with a nRF54L15 DK, tell me, and I&#39;ll ask more information about it internally.</p> <p>Best regards,</p> <p>Simon D-M</p><div style="clear:both;"></div>
