Display products have no audio, but require calling functionality. How can I remove the audio portion from HFP?
How to shut down the SCO link
Do you want to know how to reject a Sco connection?
Not entirely accurate.
During my testing, I found that after the phone call connects, I have to manually select which speaker to use every time.
How can I make the phone automatically skip this selection prompt entirely, instead of having the option pop up and then rejecting SCO afterward?
Since the product itself doesn’t have a speaker or microphone, the option popping up to select one is somewhat redundant.

选择的时候把设备改成无audio的类型看看呢
Something like this
Still exists. Are there any other ways to handle this?
This feature is mandatory and cannot be disabled individually.
Is there a quick way to disconnect immediately after the user makes a selection, then manually disconnect right away?
Is there a way to transfer HFP audio playback to a connected headset via Bluetooth?
Calling the gap_set_sco_res_by_app_flag interface can transfer the received SCO API to the upper layer.
