Bluetooth on Windows

[alexanderkoller]

On Windows (10), pairing the NXT over Bluetooth does not always seem to create a COM* serial device to which DialogOS can connect. Why?

If a COM* serial device is created, there is often the issue that SerialPort#openForNxt hangs, and eventually times out.

And if the port is opened correctly, there is sometimes a timeout after sending the getDeviceInfo bytes, before a response is sent.

Altogether, Bluetooth support on Windows seems to be so broken that I have disabled Bluetooth support by skipping serial devices in NxtBluetooth -> getFactory -> getAvailablePorts. We should debug this and then re-enable Bluetooth on Windows.
