nRF5340 audio dk failure to maintain connection after updating Galaxy Buds2 Pro software

[slswks]

I was working with the nRF5340 audio dk gateway application to connect to my Samsung Galaxy Buds2 Pro ear buds. I was able to make a cis connection and stream data bidirectionally.

Then I updated the software on the Buds2 to RS10XXUDAWF4 and now I cannot stream data between the ear buds and the gateway. I see errors in the log that seem significant: "Unable to find ASE Control Point" then "No sinks found, Disconnected." Does anyone know what that means or what changed on the new Buds2 Pro software?

Hi Ed

Would you happen to have an Ellisys Bluetooth sniffer (or something comparable) so you can see what is happening over the air? 

Otherwise it is hard to know what Samsung might have done on their side, to make it non functional between one update and the next. 

I will check internally if someone in the audio team happen to have the same airbuds, if so we can do some testing on our side to try and verify your findings. 

Best regards
Torbjørn

Thanks for the response. I'll look at getting a sniffer going to see what's going on. I wish I had a trace from before when it was working for comparison.
