One copy of my program was running in the background (maybe in a screen) and I did notice. While launching a second instance I got the error below. Maybe the error message could be more explicit to help troubleshoot it by the user.

Traceback (most recent call last):
  File "r.py", line 21, in <module>
    bd = BlueDot()
  File "/usr/local/lib/python3.4/dist-packages/bluedot/dot.py", line 401, in __init__

    self._server_sock.bind((self.server_address, self.port))
OSError: [Errno 98] Address already in use

note - would also need to check for python 2 error

Added message 

Bluetooth address B8:27:EB:FE:0C:0E is already in use - is the server already running?
