How to add the DFU OTA with SMP to a matter sample project like light_bulb

[paper555]

I would like to add smp ota firmware upgrade to the matter sample project, can you provide me with the specific steps to do so, and in which path is the ota file compiled and generated?

[Sigurd Hellesvik]

Hi,

Which protocol do you want to do OTA over? Matter or Bluetooth LE?

Regards,
Sigurd Hellesvik

According to the description here, is it possible to support both matter OTA and smp OTA firmware upgrades on the device, and if I want to add smp OTA to the matter example project, how should I do it, and is there a detailed description of the steps?

What did you change in the application for the DFU image?

(After flashing first app, but before generating dfu_applicaiton.zip)

I only change the version of the firmware before generating the dfu_application.zip. Can you use the sample of light_bulb to try ?

Im also having some difficulty in doing FOTA for this sample.

I will look more into this.

Dont know what did not work for me last time, but it worked now:

The MCUboot logs comes from me enabling logs and serial in sysbuild/mcuboot/prj.conf. I suggest that you do the same to see what your error could be from the logs

Hi, nice to see you here, I met the similar problem for adding SMP OTA, Did you only enable CONFIG_CHIP_DFU_OVER_BT_SMP, and everything is ok?

[Sigurd Hellesvik]

Specifically, I used configurations found in sample.yaml to build.

Then I enabled logs in sysbuild/mcuboot/prj.conf.

Thank you very much, I will try cmd to build tomorrow!
