Do you have a Bluetooth 4.0 device in your system? Can you see enable Bluetooth and its working in your Android environment?
(If you look at my screenshots you can see I could detect my iPhone and as well--not in the screenshots--my iPhone detected my Android-x86 environment)

Edit:
If it works with my built-in Bluetooth 4.0 adapter it will definitely work with a USB BT 4.0 adapter as well (my internal BT adapter actually shows up as being on the USB bus)

Edit:
I hope there will be a solution for me as well, running an Android emulator on my 7yo MacBook... I will possibly need an external BT 4.0 USB adapter of course cause my old one has only BT 2.0 I think.
