Kvim3 android 14 Bluetooth BSP document or tips

VIM3 Android
1

I am looking up the code of the Bluetooth Controller adapter , but have no clue, for example which USART/tty is used, and where is the Bluetooth controller code?
Any related documents? Or any tips for such topic?

I know for broadcom Bluetooth, there is the libbt directory at hardware/broadcom/bluetooth, but it seems this android 14 bsp does not use this one, which one is used?

Are there any related bsp document from amlogic?

I can receive such doc with email(based64 string): MzczNDY2MDYyQHFxLmNvbQo=

@TonyHo ，
The aosp android 14 code has some missing features. If you need to use the full functionality, we recommend that you use the Android 9 version maintained by khadas.
