• Ensure you have paired your bluetooth device with your PC first
• Select the correct port, in Windows, determine this from the Device Properties screen.
• Bluetooth via serial can be quite flakey, sometimes you just can't see the device and I'm not sure why yet!
• There is a standard read and write timeout of 0.1s, which can be changed in the code, if the timeout is triggered, the connection is stopped.
• Tested and works on Python 2.7 + 3.6 on Windows 10
