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
