 1. I am planning to do DFU update with UART 
 2. I Build smp_svr and flashed successfully when am using mcumgr its getting NMP Timeout 
 3. I added CONFIG_MCUMGR_SMP_UART=y into the prj.conf 
 4. mcumgr --conntype serial --connstring &amp;quot;com8</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 15 Sep 2022 10:58:51 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/91949/nmp-time-out-while-using-mcumgr" /><item><title>RE: NMP Time out while using mcumgr</title><link>https://devzone.nordicsemi.com/thread/386356?ContentTypeID=1</link><pubDate>Thu, 15 Sep 2022 10:58:51 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:cb4ac7c4-0e58-4d85-8174-388955e4a9a8</guid><dc:creator>Simon</dc:creator><description>&lt;p&gt;Could you do some debugging on the&amp;nbsp;&lt;span&gt;bl653_dvk and check if anything is received?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Put a break point or add printk RTT log (see&amp;nbsp;&lt;/span&gt;&lt;span&gt;&lt;a href="https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu#modify_hello_world"&gt;Modify the Hello World sample&lt;/a&gt;&amp;nbsp;how to enable RTT logging&lt;/span&gt;&lt;span&gt;) at these places to see if it&amp;#39;s executes:&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;2. In bl653_dvk board we cant run uart dfu?&lt;/p&gt;
&lt;p&gt;3. ya i diabled mass storage&lt;/p&gt;
&lt;p&gt;4. ya i did same testing but still i am getting NMP time out&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: NMP Time out while using mcumgr</title><link>https://devzone.nordicsemi.com/thread/386343?ContentTypeID=1</link><pubDate>Thu, 15 Sep 2022 09:48:41 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:9f1fb4ae-4673-4539-b49d-a292843e365b</guid><dc:creator>Simon</dc:creator><description>&lt;p&gt;I would recommend getting an nRF52833 DK:&amp;nbsp;&lt;a href="https://www.nordicsemi.com/Products/Development-hardware/nrf52833-dk"&gt;https://www.nordicsemi.com/Products/Development-hardware/nrf52833-dk&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Have you tried disabling mass storage?&amp;nbsp;&lt;/p&gt;
