&lt;p&gt;I do not have any logic analyzer here (they are quite expensive, and we are a small company.&lt;/p&gt;
&lt;p&gt;I usually turn on the board and quite soon I run the command... It would be really rare to have any activity on it.&lt;/p&gt;
&lt;p&gt;I wonder if we can debug this by getting you logs or other kind of software traces, either using the standard ble driver or any debug version you want me to run.&lt;/p&gt;
&lt;p&gt;Regards&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrfutil dfu ble seems to fail suddenly.</title><link>https://devzone.nordicsemi.com/thread/151143?ContentTypeID=1</link><pubDate>Mon, 17 Sep 2018 11:38:20 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b00179f0-3577-4bc6-8ac3-26d7c7b1c691</guid><dc:creator>Susheel Nuguru</dc:creator><description>&lt;p&gt;David,&lt;/p&gt;
&lt;p&gt;We have never tested this with Fedora Linux, and we do not have any PCs with Fedora native install. So it is hard to debug for us. Since the error occurs on dfu_transport_open() we wanted to know if there was any prior activity on UART at all. Can you sniff the UART port by a logic analyzer and post it here so that we can see if the UART port was opened before and to see if there was any activity on these lines after the command started.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrfutil dfu ble seems to fail suddenly.</title><link>https://devzone.nordicsemi.com/thread/151142?ContentTypeID=1</link><pubDate>Mon, 17 Sep 2018 07:40:48 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b93de095-d72b-40f5-b3f5-e985db63ef3f</guid><dc:creator>David Fernandez</dc:creator><description>&lt;p&gt;OK, I&amp;#39;ll wait to hear from you guys.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrfutil dfu ble seems to fail suddenly.</title><link>https://devzone.nordicsemi.com/thread/151141?ContentTypeID=1</link><pubDate>Mon, 17 Sep 2018 06:43:54 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:ebba5a5e-d4cf-4abc-9cc4-91f6f8abf62c</guid><dc:creator>Susheel Nuguru</dc:creator><description>&lt;p&gt;Sorry David, I haven&amp;#39;t heard anything from him.
