TMAP peripheral sample not advertising after flashing on nrf5340-Audio DK board

pal_722

Hi, 

I am new to nrf and have started working with nrf5340 audio dk board. I am using VS Code for programming and the SDK version used is v2.6.1.

I tested the board with blinky sample and it works fine.

I then started with TMAP peripheral code, as my application or use case in based on BLE audio transfer.
I was able to build and flash the code, but the board is not advertising and throws the below shown error.

In the build configuration, I selected nrf5340_audio_dk_anrf5340_cpuapp and chose prj.conf as configuration.

I did follow few threads in the forum, but see no difference. 
Could you please help me solve this issue?

    Hello,

    The nRF5340 Audio DK is a complex starting point when you are new to Nordic products. I recommend that you start with the nRF5340 DK instead and get to know nRF Connect SDK by going through the nRF Connect SDK Fundamentals course. After that, the Bluetooth Low Energy fundamentals course gives a great insight into our Bluetooth Low Energy solutions.

    For LE Audio, we have the nRF5340 Audio applications which are applications specifically made for the nRF5340 Audio DK. When starting with the application you start with a functioning LE Audio device. Note that the applications have the experimental tag in the latest release which means they are not production ready as is and needs to be thoroughly tested before moving to certification.

    Your specific error is ENOTSUP, that is: the controller does not support the requested feature. I suspect that this is because the SoftDevice Controller only supports ISO for multirole devices. See the full list of supported features for the SoftDevice Controller here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/softdevice_controller/README.html.

    Let me know if you need more assistance with finding the correct Kconfig symbols to enable the needed features in the SoftDevice Controller.

    I do still recommend that you get to know nRF Connect SDK in general by going through the DevAcademy courses linked above if you haven't already.

    Best regards,

    Maria

    Hi  
    I opened this ticket a week back and am waiting for a reply.
    Should I open another ticket or continue in the same ticket. 

    I am researching about the issue on other platforms too, but am not able to find a way out.
    As mentioned before, I am running short of time and have been working for a month on just a sample code.
    Kindly help me in resolving the issue
