The issue seems on Samsung. Unfortunately, we don't have S23 to test.

Maybe you can analyze their advertising package to find the differences.

Hi Amanda,

I have tested with the S24+ and did not observe the issue; however, when I tested with the S23, I encountered the stuck condition.

Based on my understanding, the scanning process on the nRF5340 should not become stuck, as the S23 is only performing advertising.

Would it be possible for you to reproduce this issue with the S23 on your side? Or, if there is any additional information I can provide to help diagnose the situation further, please let me know.

Thank you very much for your assistance.

Best regards,
Jimmy

Hi Amanda, got it.

Thanks for your feedback.

I will try that with S24.

Thanks again for your help.

We cannot reproduce the issue with S24.

Hi Amanda,

Thanks for your suggestion.

I initially encountered this situation without making any changes.

I added that for debugging because I noticed that the device does not connect to other broadcasts.

Additionally, if I only use the nRF5340 Audio DK as the broadcaster, I can see the logs printing continuously for around 12 hours.

Best Regards,

Jimmy

Hi,

We are using S24 for testing, but cannot see any issue when enabling/disabling the broadcaster from S24. The broadcast sink can always sync again.

I would assume the log added by you might trigger the race condition. It's better not to modify the host code.
