Are multiple Bluetooth adapters under Android possible?

Question

Are multiple Bluetooth adapters under Android possible (e.g in order to be able to connect to more than 7 devices through these adapters)? Android API does not even mention the possibility of accessing more than one adapter: https://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html#getDefaultAdapter()

I have no restrictions on root or running native code.

Answer 1

Even it's not possible with Android API, if Android device has OTG then USB BT dongle can be attached to that device (at least is possible connect to Android several BT SPP devices).
