Can you provide me some .btt files about le audio?

[Hhhhh]

I dont have Ellisys, but I already install Ellisys Bluetooth Analyzer on my PC.

I got a .btt file in this ticket , but it seems something wrong.

I want some .btt files(contain complete process) about 2 CISes and BISes(The application “nrf5340 audio”) to study LE Audio.

Thank you for your help.

Hello,

I will try to provide some traces for you.

Do I understand correctly that you want to investigate two topologies?

1. CIS gateway left and right CIS headsets
2. BIS gateway to BIS headset

Best regards,

Maria

[Hhhhh]

Yes, both two headsets and one gateway.

Thank you.

Ok, Thank you. Look forward to your reply.

Hello,

Here are the traces that I collected:

1881.nRF5340_audio_BIS_1GW_2HS.btt

4431.nRF5340_audio_CIS_1GW_2HS.btt

I used the nRF5340 Audio application from nRF Connect SDK v2.9.0.

I hope they are useful to you.

Best regards,

Maria

Thank you Maria. The BIS is ok, it really help me , but the CIS seems loss link-key?

[Maria Gilje]

My apologies, let me find out how to get the link key as well and then create a new trace for the CIS traffic. Thank you again for your patience.

Best regards,

Maria
