Use existing sockets for communication

[HubertZhang]

I tried to implement a swift version of joycontrol for macOS and I found I can actually setup the SDR broadcast in swift then expose some sockets for connected devices. Then joycontrol can use existing sockets and need not to setup bluetooth things on different OS itself.

@HubertZhang I've been looking at porting this to macOS and haven't seem to found a reliable strategy with the public SDK. What have you been using to communicate with the bluetooth stack?
