CONFIG_CHIP_DFU_OVER_BT_SMP not work

[Denghongyan]

Hello, 

We use NCS2.9.0 and NRF54L15-DK do the matter development, and we use template demo, just enable CONFIG_CHIP_DFU_OVER_BT_SMP in root prj.conf, then we do the ota test: 

Matter over thread ota is ok, but smp ota cannot work, here is my andriod nrfconnect app log:

Should I config any other params?

Hi,

Can you check if the following is set for your project? (For example by checking build/template/zephyr/.config):

CONFIG_MCUMGR_GRP_OS

Thanks for your reply, I checked, CONFIG_MCUMGR_GRP_OS=y is ok in  build/template/zephyr/.config

Error 8 is "not supported", you see, so I just wanted to rule out that the management group was enabled.

From sample.yaml of the template, I see that they set both these for DFU:

"
- CONFIG_CHIP_DFU_OVER_BT_SMP=y
-CONFIG_NCS_SAMPLE_MATTER_OPERATIONAL_KEYS_MIGRATION_TO_ITS=y

"

Try to use both.

Also, do you get any logs from the nRF when DFU does not work?

I tried, but same error, and I cannot change the version in VERSION file now, I don't know what's wrong, and tomorrow I will try to use cmd to build the project.

And I try to turn on the log in prj.conf:
CONFIG_BT_LOG_LEVEL_INF=y

CONFIG_DFU_TARGET_LOG_LEVEL_INF=y
But got no logs any more during OTA:

What do you mean "cannot change" here?
