I have made multiple connections to a single UUID.
It is like TCP. The UUID just says what port the Bluetooth Server is on. I could have a server running on Bluetooth port 1. Then I could make 2 or 3 simultaneous connections to it just like I can make 2 or 3 simultaneous connections to port 80 of Yahoo's web server.
