Bluetooth connectivity audio profile issue

I am using NVIDIA Jetson Orin NX with linux version 5.15, currently working on bluetooth.
I have 2 different bt headset say A and B.
when i connect A, the audio profile is A2DP. Then i can change it manually to HFP. After reconnect it automatically select A2DP.

But for headset B, it is not working as expected. First time it select A2DP. but when I reconnect, it select HFP instead of A2DP.
In some scenario it disconnect automatically in HFP profile.

I tried both with laptop and some another devices, it is working as expected.

Hello @harikrishna.mg and welcome to the NVIDIA developer forums.

We have a dedicated Jetson category, I hope you don’t mind if I move your post over there.

Thanks!

Hi @DaneLLL

Thank you for your response. I’ve carefully reviewed the suggestions you shared and can confirm that the recommended changes had already been implemented on my end. Unfortunately, the issue still persists.

If there are any additional steps or configurations that I might have missed, I would greatly appreciate your guidance.

Hi,
There are some discussion in the topic:
Bluetooth HFP switching Error

We are uncertain how Ubuntu handles this. Would suggest search online or see if other users can share experience.
