Have you modified the sample, if so what modifications have you done?<br /><br />Regards,</p> <p>Benjamin</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/552667?ContentTypeID=1Tue, 28 Oct 2025 15:29:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:203698e7-a9d4-45e3-a951-e761e25c7a13SBou<p>Hi Benjamin.</p> <p>I try copy the sample in the path C:\ncs\LightBulb300 and finish the buil successfully but now I can&#39;t find the device in the Alexa APP.</p> <p>On the other hand, I must say that we use a custom board and when do the same steps with the sample light_bulb in from the SDK 2.5.0 it works fine.</p> <p></p> <p>Regards.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/552645?ContentTypeID=1Tue, 28 Oct 2025 13:44:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1c272e9-7f8f-4ac6-8f16-8b55342c1cdeBenjamin<p>Hi Sergio,</p> <p>Could you try copying the sample to a shorter path? There have been issues with long path names on Windows.</p> <p>Best regards,<br />Benjamin</p><div style="clear:both;"></div>
