https://devzone.nordicsemi.com/f/nordic-q-a/118757/nrf5-mesh-serial-and-serial-dfu-mergeHi Nordic, I am trying to merge nrf5 mesh serial and serial DFU, I have added serial DFU to serial mesh example, it is compiled successfully and do not show any errors in debugging. But when I start DFU it gets stuck after port open, echo and flashen-USTelligent Community 13Thu, 13 Feb 2025 10:24:51 GMThttps://devzone.nordicsemi.com/thread/522817?ContentTypeID=1Thu, 13 Feb 2025 10:24:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0aa71a40-b650-4480-a19e-a9767e55264dhim<p>Hi,</p> <p>We have been using SDK v4.2.0 in our projects.</p> <p>DFU project used ;- dfu_nrf52833_xxAA_s113_7_0_1</p> <p>Serial project used :-&nbsp;serial_nrf52833_xxAA_s113_7_0_1</p> <p>Bootloader used :-&nbsp;mesh_bootloader_gccarmemb_nrf52833_xxAA.hex</p> <p></p> <p>Sometimes it(Serial+DFU) gets stuck at echo packet, target don&#39;t reply to echo command.

Those SDKs are not recommended for new projects. For more information, see <a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf-connect-sdk-and-nrf5-sdk-statement">nRF Connect SDK and nRF5 SDK statement</a>. If you still want to use nRF5 SDK, at least you should use nRF5 SDK for Mesh v5.0.0 and nRF5 SDK v17.0.2.</p> <p>nRF5 SDK has several DFU bootloaders. Which exact DFU solution are you trying to merge into the mesh serial sample? I.e., what exact samples are you merging?</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
