BT851 USB dongle in Android

I am running Android-9 on Rock960 board and would like to use the BT851 USB dongle (Bluetooth). The dongle supplier only give info for Linux but not Android.

My understanding Android using different BLE Stack (not BlueZ),
Is there tool in Android same as “hciconfig” to re-attach stack using ADB commands ?

Forum search is a great thing;

Read the whole thing and understand it.
Also note that what rockchip passes off as Android is pretty severely butchered, so don’t be too surprised if nothing works as expected.
