Hi Dejans,

Thanks for your feedback.

Unfortunately, I don't have another phone that supports Auracast.

I will find one to test if possible.

Thanks again for your help.

Best regards,

Jimmy

Hi Jimmy,

It seems that the issue with the drift is coming from the phone, not from controller. Do you have any other phone (except for S23 and S24) to test with?

Dejan

Hi Dejans,

After reviewing the situation, I confirmed that there are no audio issues. However, the devices consistently remain in PRES_STATE_WAIT, which I guess is unexpected.

Best regards,

Jimmy

Hi Jimmy,

We have done some testing using S24 as broadcaster (without encryption) and 2 audio-dks as broadcast receivers. These are current observations:
1. there were no issues for broadcast sink to synchronize to S24 for around 12 minutes after boot-up.
2. after that time, reset on the broadcast receiver caused issue similar to what you reported, but audio quality did not seem to be affected. Without reset, there were no issues on the audio-dk.
We will investigate this further.

Is there any audio quality issue on your end?

Best regards,
Dejan

Hi Dejans,

I tried to remove broadcast encryption and the result is the same.

Hi Jimmy,

What happens if you remove broadcast encryption? Do you get different result?

Hi dejans,

Thank you for your prompt reply and assistance.

Yes, I changed the settings to BIS. Below are configurations I added.

CONFIG_TRANSPORT_BIS=y
CONFIG_BT_AUDIO_BROADCAST_NAME="JimmyS23"
CONFIG_BT_AUDIO_BROADCAST_ENCRYPTED=y
CONFIG_BT_AUDIO_BROADCAST_ENCRYPTION_KEY="1234"

Attachments are ADK#1 and ADK#2 logs.

I only verified the issue using two different Samsung S23 devices, and unfortunately, the results remain the same.

Thanks again for your help.

Best regards,

Jimmy

Hi,

Can you send log from device ADK#1?

Have you made any changes in the application on both boards?

Have you verified the behavior with any other phone? Are there any differences in the output?

Best regards,
Dejan
