Hi. I still have issues with building. It takes too much time, so I gave up for now... Is stereo support planned in a later SDK version? Then I will just wait for this I guess.

[quote user="JeroenT"]I get a different error now with the stereo_bis_receiver_pre270 branch. See below.[/quote]

It's a branch of NCS v2.7.0. Please use NCS v2.7.0 to build.

Hi! I installed it using the Toolchain Manager. I did not know the cmd prompt had to be opened using the Toolchain Manager. Maybe this can be added to the build instructions on this page: Building and running nRF5340 Audio applications

I get a different error now with the stereo_bis_receiver_pre270 branch. See below.

I do not get this error when building the standard v2.8.0 nrf5340_audio example.

I hope you can help me. We really want to use the NRF5340 in our product, but the build system is a bit problematic now...

How do you install the NCS? I would suggest to Installate with Toolchain Manager, and then open the command prompt for NCS v2.8.0 to build.

Hi. I am trying to get stereo example working, but I get a build error. With the original v2.8.0\nrf directory it just works. I hope you could help me to correct my way of building it. I take these steps:

- Open cmd prompt

- Type: cd ncs\v2.8.0

- Type: git clone https://github.com/rick1082/sdk-nrf

- Type: cd sdk-nrf

- Type: git checkout stereo_bis_receiver_pre270

- Type: cd applications\nrf5340_audio\tools\buildprog

- Type: buildprog.py -c both -b debug -d both

FATAL ERROR: command exited with status 1: 'C:\Program Files\CMake\bin\cmake.EXE' --build 'C:\ncs\v2.8.0\sdk-nrf\applications\nrf5340_audio\build\dev_headset\build_debug'

You can refer to the test section of the Broadcast sink (BIS /headset) and Broadcast source (BIS /gateway).

[quote user="JeroenT"] Is it possible to change the reception on the headsets/receivers to stereo?[/quote]

Check out the branch in this post.

[quote user="JeroenT"]Can I just add an extra headset/receiver to nrf5340_audio_dk_devices.json?[/quote]

Yes.

Hi Amanda,

Thanks for your reply.

I deleted the build folder and after rebuild the .config indeed shows CONFIG_TRANSPORT_BIS=Y. I am not sure how to verify that Auracast is active now. Is it possible to change the reception on the headsets/receivers to stereo? Can I just add an extra headset/receiver to nrf5340_audio_dk_devices.json?

Hi,

Try to delete the build folder and build again. You can check the .config file under build/nrf5340_audio/zephyr to see whether the CONFIG_TRANSPORT_BIS=Y takes effect or not.

Regards,
Amanda H.
