nrf5340 audio DK cannot configure BIS mode with two gateways

[uzer123]

I can successfully run BIS mode with 3 nrf5340 audio DK (one DK connected with USB with the PC as the source, and two DKs as receivers).

But the buildprog.py script gives an error when i add 

CONFIG_BT_USE_AUDIO_BROADCAST_NAME_ALT=y

in the prj.conf file according to the instructions here

The error i get is: 

myprojectfolder/nrf5340_audio2/prj.conf:66: warning: attempt to assign the value 'y' to the undefined symbol BT_USE_AUDIO_BROADCAST_NAME_ALT

I use windows 10, nrf connect SDK v2.2.0 with Vs Code extension.

Hi,

Are you using the debug version or the release version?

If debug version, then changes should be made in prj.conf and for release version, it should be to prj_release.conf

If your issue persists, could you attach your prj.conf or prj_release.conf here?

Best Regards,

Priyanka

I edit the prj.conf and i compile the debug version:

python buildprog.py -c both -b debug -d both -p -f

prj.conf is the default. I just add:

CONFIG_TRANSPORT_BIS=y
CONFIG_BT_USE_AUDIO_BROADCAST_NAME_ALT=y

If i add only 

CONFIG_TRANSPORT_BIS=y 

i successfully run the BIS example. So i guess my prj.conf file is working correctly.

Hi,

The main was update with some changes. So maybe you are on the old hash. Could you open a command prompt, go to the project location, for eg. cd <your path>\nrf\applications\nrf5340_audio> 

Then try the following commands:

git fetch

git checkout main

git pull

west update

Then try building with the Configs enabled in prj.conf

I tried your steps and I tried to find any differences with the latest repo, but i cant find anything. Here (latest nrf connect sdk version) i can find 

CONFIG_TRANSPORT_BIS, but i cannot CONFIG_BT_USE_AUDIO_BROADCAST_NAME_ALT

Any other step to try?

I has tried replicating your issue and this was how I solved it. 

Which nRF Connect SDK version are you trying with?

I had tried with the v2.2.0
