&lt;p&gt;Looks like the ADC goes into saturation during scenario B-1. Are you building for the nrf54l15DK?&amp;nbsp; If so, I suspect the reason is because&amp;nbsp;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span&gt;P1.14 is also connected LED3 on the DK.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Do you see the same result if you use a ADC GPIO that&amp;#39;s not connected to a LED that Matter uses?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Kind regards,&lt;br /&gt;Andreas&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
