 i was testing mcumgr ota from uart, but found that the speed is slow how can i improve this? 
 i have change uart baud to 460800, but did not help. for customer usage, if app_update.bin is over400Kb, this process will be over 3 minutes</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 22 May 2024 07:44:35 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/101419/mcumgr-uart-smp-speed-is-slow" /><item><title>RE: mcumgr uart smp speed is slow</title><link>https://devzone.nordicsemi.com/thread/485307?ContentTypeID=1</link><pubDate>Wed, 22 May 2024 07:44:35 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:845f48f2-37c8-45aa-bff7-ec4e7b076b39</guid><dc:creator>Sigurd Hellesvik</dc:creator><description>&lt;p&gt;nrfutil does not have finished support for mcumgr functionality yet no.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: mcumgr uart smp speed is slow</title><link>https://devzone.nordicsemi.com/thread/485297?ContentTypeID=1</link><pubDate>Wed, 22 May 2024 07:21:05 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d73b31a3-ba7b-4dc4-a895-33daaa2ff915</guid><dc:creator>Sigurd Hellesvik</dc:creator><description>&lt;p&gt;I will inquire about nrfutil.&lt;/p&gt;
&lt;p&gt;In the meantime, Zephyr now list some other alternatives than mcumgr-native-cli.&lt;br /&gt;See &lt;a href="https://docs.zephyrproject.org/latest/services/device_mgmt/mcumgr.html"&gt;https://docs.zephyrproject.org/latest/services/device_mgmt/mcumgr.html&lt;/a&gt; for a list. Most of these will be faster than the old tool&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: mcumgr uart smp speed is slow</title><link>https://devzone.nordicsemi.com/thread/485256?ContentTypeID=1</link><pubDate>Wed, 22 May 2024 02:23:38 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d4ae016b-38b4-4317-b55a-5102189c6fa1</guid><dc:creator>William.wei</dc:creator><description>&lt;p&gt;Hi Sigurd,&lt;/p&gt;
&lt;p&gt;may i ask if the nrf util is ready for ncs mcumgr function, i have already installed 91 command, but don&amp;#39;t know how to use it &lt;span&gt;for MCUboot DFU.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Regards,&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;William.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: mcumgr uart smp speed is slow</title><link>https://devzone.nordicsemi.com/thread/434193?ContentTypeID=1</link><pubDate>Mon, 03 Jul 2023 11:46:04 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:879e6f14-6c3b-472c-823e-1f27058bf38e</guid><dc:creator>Sigurd Hellesvik</dc:creator><description>&lt;p&gt;Hi William,&lt;/p&gt;
&lt;p&gt;Unfortunally, mcumgr is known to be quite slow.&lt;/p&gt;
&lt;p&gt;The support is not ready yet, but &lt;a href="https://www.nordicsemi.com/Products/Development-tools/nRF-Util"&gt;nrfutil&lt;/a&gt; has some support for MCUboot DFU and is a lot faster.&lt;br /&gt;When nrfutil has full support for MCUboot DFU, I suggest you switch to that.&lt;/p&gt;
&lt;p&gt;For now, see &amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/86191/mcuboot-slow-with-nrf52840-zephyr-usb-cdc_acm-protocol"&gt;MCUBOOT slow with nRF52840 / Zephyr / USB CDC_ACM protocol&lt;/a&gt; for how to speed up mcumgr.&lt;/p&gt;
