Building Auracast Broadcast example code

[astorm]

I have three 5340 Audio DKs (PCA10121) and I am trying to demonstrate one as the broadcaster and the other two as headsets with audio transferred between them but NRFconnect within VScode fails to build any of these with the latest tool V3.0.2.

I have followed the instructions here nRF5340 Audio: Broadcast source but the VScode build fails, the preferred python script fails as does building from the command line suggesting something a wrong at a deeper level. 

It seems I have to ensure CONFIG_TRANSPORT_BIS=y in "prj.conf" as this missing, but even when added the error is still the same.

VScode/NrfConnect failure:

Python Script failure:

I also noticed this script is going to try to call "nrfjprog" which is depreciated and not easily downloadable anyway, so always going to fail.

Command line failure:

Incidentally, I have successfully built, flashed and tried out other BLE example code for the larger nRF5340 dev kit so this problem is audio example specific.

Any ideas how to get this example to build? Thanks :-)

Hi Andrew,

The nRF5340 Audio application does not support building and programming using the nRF Connect for VS Code extension. You must use either the provided Python script (`buildprog.py`) or the command line with `west` to build and program the application. 
See the section highlighted as important here: Building and running nRF5340 Audio applications

Python Script failure:

As of NCS v3.0.0 and later, the 'buildprog.py' script requires the '-t' or '--transport' argument to specify either 'unicast' or 'broadcast'.
For example, to build the broadcast gateway (source), use:
python buildprog.py -c app -b debug -d gateway -t broadcast

To build headsets:
python buildprog.py -c app -b debug -d headset -t broadcast

If you omit '-t', the script will fail as you observed. See here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/applications/nrf5340_audio/doc/building.html#script_parameters_for_building 

Also note that if you are using an older SDK (e.g., v2.9.1), the script syntax is different and does not accept '-t'. Make sure your documentation matches your SDK version: (8) Nordic DevZone 

Command line failure:

This error means the `west` tool is not installed or not available in your environment. Make sure you have installed the nRF Connect SDK toolchain using the Toolchain Manager, which sets up 'west' and all dependencies. Make sure that all the installation steps are done correctly: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/installation/install_ncs.html 

Regards,

Swathy

hello Sathy, 

I can understand why the python buildprog.py command is failing without the -t argument but I copied the line from Building and running nRF5340 Audio applications instructions.

 

Even with the -t argument the error is:

West tool is installed at "C:\ncs\toolchains\0b393f9e1b\opt\bin\Scripts" on my pc and this directory has already been entered as an environment variable so Windows can in find it.  

 

Even if I "cd" to the "scripts" directory and run it west from there just to check it can be found at least, this error results:
