Bluetooth headset supported?

Hello,

I checked Bluetooth headset profile on rockpi4 android9.
Now, Bluetooth headset service not running.

Because, headset settings is disabled by overlay settings.

    device/rockchip/common/overlay/packages/apps/Bluetooth/res/values/config.xml
 <resources>
    <bool name="profile_supported_a2dp_sink">false</bool>
    <bool name="profile_supported_hdp">false</bool>
    <bool name="profile_supported_hs_hfp">false</bool>
    <bool name="profile_supported_hfpclient">false</bool>
   ...

I tried to test by custom build image with above change settings( false -> true ).
But Headset don’t work(Service is avaiable but don’t work).

Has it been disabled for some reason?

In a different thread, the Radxa Team says that the BT Headset Profile is not yet supported.
