Hi,

You can even add Custom Bluetooth profiles. There’s a whole range of pre-existing profiles to cater with common situations (see What is… a GATT Service (Bluetooth Smart)) – but if you need to add Bluetooth profiles that do not have HAL (hardware abstraction layer) interfaces provided by Android, you have to do three things:

1. supply an SDK add-on download to make the profile available to app developers
2. make the APIs available in the Bluetooth system process app (packages/apps/Bluetooth)
3. add the APIs to the BlueDroid stack (external/bluetooth/bluedroid)

Hi, Steven

Because our reference board hardware strict(the PCM IO has not pined out), so the HFP HF role has not enabled. If you want to enable it, you should enable PCM pin out first in hardare design.
