https://devzone.nordicsemi.com/f/nordic-q-a/117628/issue-about-dfu-of-ncs-use-uartDear Nordic Engineers I used NCS2.9.0 to develop a device based on nRF52840 and I would like to use UART to DFU the device based on SMP. Now, I test SMP samples and use the MCUmgr command line to succeed in DFU the device on Windows. I want to achieveen-USTelligent Community 13Thu, 02 Jan 2025 07:57:33 GMThttps://devzone.nordicsemi.com/thread/516595?ContentTypeID=1Thu, 02 Jan 2025 07:57:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9c8c4ca3-c10a-459a-ab16-31611338ca33Sigurd Hellesvik[quote user=""]<span>Does have detailed samples on MCU?</span>[/quote] <p>Here is an unofficial sample for an <a href="https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/client_smp/smp_client_ble">SMP Client</a>.</p> <p>I hope it can show you how encoding and decoding can work.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/516551?ContentTypeID=1Tue, 31 Dec 2024 05:19:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:44975039-e0ab-4e47-8a5d-6ed3296e1f39curry<p>Hi，</p> <p>Yes, we would like to use one of the MCU for DFU with nRF.</p> <p>Regards,</p> <p class="last-node">curry</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/516484?ContentTypeID=1Mon, 30 Dec 2024 11:10:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f38b5f72-5057-4784-9101-6eb05a6b9dd2Sigurd Hellesvik<p>Hi,</p> <p>Do you mean that you run two MCUs and want to DFU the nRF from another MCU?</p> <p>Or do you still want to DFU the nRF from a PC?</p> <p>Regards,<br />Sigurd Hellesvik</p><div style="clear:both;"></div>
