NRF5340 LE AUDIO.Erroe Log: LOG_DBG("PA sync with broadcast source with ID 0x%06X lost", sink->broadcast_id);

huniu

Hi:

this is my old issue:

https://devzone.nordicsemi.com/f/nordic-q-a/97667/nrf5340-le-audio-stream-not-associated-with-an-ep

I creat a new case for more help.

    Hi,

    Could you add some more information about your application?

    e.g., the setting for retransmission times, the bitrate, and also how many BIS are you working with?
    And would there be a way to replicate this easily with our nRF5340-(Audio)-DK?

    Please also provide logs from the headset side.
    Since the terminology we used in here could lead to misunderstandings.
    When you mentioned losing synchronization, would that be
    1. The synchronization in audio_datapath module is not working correctly, cause the drift and presentation compensation keeps triggered and causing the bad user experience, or
    2. The headset keeps lost sync from the periodic advertising. This could related with the missing packets from primary advertising channels

    HI:

    I'm sorry for the late response.

    The probability of this problem occurring is very strange, sometimes it does not occur for several days, and sometimes it occurs multiple times within a few minutes:

    The following is the log of headset:

    1.I believe that this issue can be replicate with nRF5340-(Audio)-DK, but it is not easy because it cannot be reproduced stably. By synchronization loss, I mean between the headset and the gateway。

    2.my project base on NCS 2.2.0,one headset+one gateway.i have't change any param such as:the setting for retransmission times, the bitrate and so on.

    Hi,

    1) Do you know if there is interference nearby the headset or gateway, like a WIFI router or some other devices which is using 2.4GHz?

    2) It would be useful with the debug log level logs from le_audio_bis_headset.c , this can be achieve by set CONFIG_BLE_LOG_LEVEL_DBG=y, so we can know more about this "disconnection" procedure.

    3) Also, if possible, could you test with NCS v2.3.0 as well, to see if there is any change in how this issue behaves?

    1.I am not sure if there is interference, I focus on wireless product developmentt ,so there may be hundreds of Bluetooth and WiFi devices around me. Finding a relatively clean environment for testing is really worth trying, but it takes some time.

    2. I will open this and retrieve more logs again.

    3. It's worth trying, but it will take some time,  I'll respond when I'm ready.
