Hi Rajendra,

As your setup is not the same as described in this ticket, (depending on your issue) discussion might be unrelated to the initial question asked here. I would recommend that you open a new ticket and describe your issue there.

Hi Dejan

I am not using a mobile device, but the nRF5340 DK board. Any improvements on that?

Warm Regards,
Rajendra.

Hi,

You could try to debug your issue by for example running addr2line on the faulty instruction address.

Hi Dejan,

I am not sure whether it is a debug or release version. I made changes in prj.conf and it is working in unidirectional and for the client application as well.

Below are the details of my application with nRF5340 Audio DK.

Hi,

Did you build debug or release version of the application?
Kconfig option CONFIG_STREAM_BIDIRECTIONAL needs to be added to a proper project configuration file. Each of the build versions has its own configuration file - applications/nrf5340_audio/prj.conf (for the debug version) and applications/nrf5340_audio/prj_release.conf (for the release version).

Could you provide full project configuration that you used on nrf5340_audio-dk?

Dejan

Sorry, there was typo in previous reply.
There is no option available to enable LE Audio in developer options.

BTW, by disabling CONFIG_STREAM_BIDIRECTIONAL in prj.conf, streaming is successful to the headset and can hear the same. This is done using Pixel8 Pro.
However when I am going for bidirectional stream, Failed to set up codec is observed.

Could you help here to enable bidirectional stream ???

Thanks a lot 🙂 !!!

Hi,

Thank you for sharing the video.

Can you try to enable LE Audio via Developer options?

Yeah, I can see a switch to enable LE Audio feature. When I am trying to enable the same however switching to LE Audio is not happening.

Hi,

Have you updated your phone to the newest Android version?

After connecting to the CIS headset, you could try to check the device settings for CIS gateway in the Bluetooth page to see if there is a switch for enabling LE Audio feature.
Alternatively, you could try to enable developer options and support for LE Audio on your phone. It might be that support for LE Audio is not enabled by default.

Best regards,
Dejan

I have added the above mentioned CONFIGs in the prj.conf file.

I have not tried due to unavailability of mobiles with LE audio support.

Thanks a lot 🙂 !!!
