How to use UART to DFU on NCS2.8.0?

[Hannibalhz]

Dear Nordic Engineers

I used NCS2.8.0 to test the DFU function. As we all know NCS2.6.0 used the mcumgr-cli tool to send the fireware of the DFU image.  But on NCS 2.7.0 and 2.8.0, it's changed.

I didn't find any course on Academy.

https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/topic/exercise-1-dfu-over-uart/

I read the doc of nRFutil and found a command [nrfutil device program --traits nordicDfu --firmware path_to_some_dfu_package.zip]

so I would like to know:

1. What is the new command of the serial DFU, does that use this command [nrfutil device program --traits] to do?

2. How to use the new command to perform DFU (based on SMP) via serial port, does have detailed documentation?

Best regards,

Hannibal

Hi,

mcumgr-cli is still recommended for SDK v2.7.0 and v2.8.0 and should work with the same commands as you've used before. Mcumgr dfu support in nRFutil is currently limited to our Thingy boards.

Best regards,
