Building nrf5340_audio_dk projects

[skajam66]

Hi,

I can build and program the broadcast_source sample application using the Python script:

% python3 tools/buildprog/buildprog.py -c both --pristine -b debug -d both -p

This runs fine and broadcasts as expected. However, I cannot get the application to run when using the command line:

west build -b nrf5340_audio_dk/nrf5340/cpuapp -d build_broadcast_source --pristine
west flash --build-dir build_broadcast_source

This builds and flashes OK but does not broadcast. The main LED is blue (not green) and LED 1 does not flash blue.

Can you see what I might be doing wrong?

Hi, 

It requires -DEXTRA_CONF_FILE=".\broadcast_source\overlay-broadcast_source.conf" for the broadcast gateway.

Select the BIS mode by setting the CONFIG_TRANSPORT_BIS Kconfig option to y in the applications/nrf5340_audio/prj.conf file for the debug version and in the applications/nrf5340_audio/prj_release.conf file for the release version. Also, check Building and programming using command line and nRF5340 Audio: Broadcast source.

Amanda H.

Hi Amanda,

That file does not exist. What should it contain?

(I'm using SDK v2.9.1)

Hi, 

Sorry not check your NCS version earily. That's not for v2.9.1.

For v2.9.1: 

Select the BIS mode by setting the CONFIG_TRANSPORT_BIS Kconfig option to y in the applications/nrf5340_audio/prj.conf file for the debug version and in the applications/nrf5340_audio/prj_release.conf file for the release version. Also, check Building and programming using command line and nRF5340 Audio: Broadcast source.

Hi Amanda,

>> Select the BIS mode by setting the CONFIG_TRANSPORT_BIS Kconfig option to y

That is what I am doing. Here is prj.conf:

Building with the Python script works and that must also use prj.conf so it must be OK.
