Re: Bluetooth Driver

Just split up your exception handling (what do you mean by "valid 
exception"?). Once you catch a SocketException (or similar), you 
shouldn't have any problems with categorizing the problem.

Another tipp: let em ping frequently. Bluetooth connections aren't as 
stable as usual socket connections for some particular reasons, that are 
plain to see. So the exception might be thrown before the trouble raises 
and you even might reconnect in time.

I highly appreciate writing a very sophisticated Connection (-Pool) 
Manager since Bluetooth surprises in several cases. Keep in mind, that 
there are lots of different BT stacks. E.g. a Widcomm stack works 
completely different from BlueZ asf..

Best,

Roger
