Can you help with why I get this serial debug message when trying to start Headset nrf5340_Audio DK in DFU mode
HR [00:00:02.068,450] <err> dfu: SMP_SVR Advertising failed to start (ret -11)
I am building the CIS example using the command - nRF5340_Audio application unchanged
python .\buildprog.py -c both -b debug -d both -m internal -M (--pristine)
After I load onto the DK I see the correct Serial debug and both Headset and Gateway are working as expected.

Issue
However, when I try and run the DFU Mode (long press BTN 4 while rebooting). I get this err’d debug
