&lt;p&gt;Could you clarify how the devices are connected? Specifically, which device is connected to your PC, and which one is the DFU target?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I also recommend sharing the complete log to get a better understanding of the issue. Additionally, please provide details on the command you are executing and the response from the logs.&lt;/p&gt;
&lt;p&gt;Furthermore, please check how the nRF device is detected on your PC. I am using Windows, and when I check my Device Manager, it appears as shown below:&lt;/p&gt;

&lt;p&gt;Please note that the link you are referring to is based on an old version of the nRF Util tool (&amp;lt; v7.0.0), which is no longer compatible with newer versions. What version of nRF Util are you working with? (I should have asked this before.) I am using version 7.12.0, and the documentation I referenced also applies to newer versions.&lt;/p&gt;
&lt;p&gt;When you check the dfu ble command, you will see that it requires a second nRF device connected to the PC, which acts as the BLE adapter.&lt;/p&gt;

&lt;p&gt;&lt;br /&gt;I am wondering how to use a built in BLE interface that I cannot see enumerated as a COM port.&amp;nbsp;&lt;br /&gt;Is there a driver I need to install?&amp;nbsp;&lt;br /&gt;&lt;br /&gt;You&amp;#39;re using windows and it is on COM3, I don&amp;#39;t see any BLE adapters as a COM port in windows, or a /dev/tty on mac or RPI linux.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: DFU cycle testing</title><link>https://devzone.nordicsemi.com/thread/522127?ContentTypeID=1</link><pubDate>Mon, 10 Feb 2025 07:39:32 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:91776ac7-d644-42c5-b139-3105cb710ae2</guid><dc:creator>Menon</dc:creator><description>&lt;p&gt;Hello,&lt;/p&gt;
&lt;p&gt;Sorry for the confusion, I was referring to the nRF Util command &lt;a href="https://docs.nordicsemi.com/bundle/nrfutil/page/guides-nrf5sdk/dfu_performing.html#performing-a-dfu:~:text=For%20example%2C%20to%20perform%20a%20DFU%20procedure%20using%20app_dfu_package.zip%20over%20Bluetooth%20Low%20Energy%20on%20an%20nRF52%20device%20connected%20to%20COM3%2C%20where%20MyDevice%20is%20the%20remote%20Bluetooth%20Low%20Energy%20device%20being%20upgraded%2C%20enter%20the%20following%20command%3A"&gt;mentioned here&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;&lt;span class="s1"&gt;Where are you able to see that COM3 is the BLE adapter? Did I miss some documentation?&lt;br /&gt;I&amp;#39;ve been running python scripts with the bleak library, and not having to supply the adapter.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span class="s1"&gt;&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: DFU cycle testing</title><link>https://devzone.nordicsemi.com/thread/521988?ContentTypeID=1</link><pubDate>Fri, 07 Feb 2025 14:54:09 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f1d2ad3b-0c52-4798-bafc-0a753f7dee94</guid><dc:creator>Menon</dc:creator><description>&lt;p&gt;Hello,&lt;/p&gt;
&lt;p&gt;I am not sure if I fully understand your query. nrfutil does not require a COM port while performing BLE DFU. Please refer to the &lt;a href="https://docs.nordicsemi.com/bundle/nrfutil/page/guides-nrf5sdk/dfu_performing.html#performing-a-dfu"&gt;section &lt;/a&gt;&lt;em&gt;&lt;a href="https://docs.nordicsemi.com/bundle/nrfutil/page/guides-nrf5sdk/dfu_performing.html#performing-a-dfu"&gt;Performing DFU&lt;/a&gt;.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;The command:&lt;br /&gt;&lt;code&gt;nrfutil dfu ble -pkg app_dfu_package.zip -ic NRF52 -p COM3 -n &amp;quot;MyDevice&amp;quot; -f&lt;/code&gt;&lt;/p&gt;
&lt;p&gt;In this command, the COM port mentioned is not for the DFU target. Instead, it refers to the COM port of the BLE adapter, while the DFU target is &amp;quot;MyDevice.&amp;quot;&lt;/p&gt;
&lt;p&gt;Which SDK version are you using? Are you working with the nRF5 SDK?&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;br /&gt;Abhijith&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: DFU cycle testing</title><link>https://devzone.nordicsemi.com/thread/521806?ContentTypeID=1</link><pubDate>Thu, 06 Feb 2025 18:48:53 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:084348d4-25aa-40d5-9740-cf6873abd100</guid><dc:creator>ms360</dc:creator><description>&lt;p&gt;I see the COM port is for the BLE interface. How does that work?&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Is that HCI0 on the RPI?&amp;nbsp;&lt;br /&gt;WHat&amp;#39;s the mac and windows equivalent?&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
