Hi John,

I am not sure what you refer to as v1.2.6. I assume your nRF Connect SDK (NCS) version is 2.5.0. Can you confirm this?

Audio controller version can be found in the bin folder of your application. For the NCS version 2.5.0 it should probably be 3393. Can you check and confirm this?

Best regards,
Dejan

Hi Dejan,

NCS version is 1.2.6 and SDK version is 2.5.0.

The version of Audio controller works with bluez5.66 is Intel AX210, which is a controller supports le audio.

Hi Dejan,

1. Download image by command

"python buildprog.py -c both -b debug -d both -p -f",

then nrf5340 audio dk works as headset, and let Ellisys device work at the same time

2. on bluez5.66 side, use "bluetoothctl", then "power on", after that,

a. "scan on", then get nrf5340 audio device,

b. "scan off", to stop scan

c. connect ****, **** is the address of the device with name of nrf5340 audio

But connect fail, so get Ellisys log as attached before. It fails as pairing problem.

BTW, intel ax210 has bluetooth le audio controller module, and works with bluez.

Best regards,

John
