What are the stack events that are thrown, is seems I am having trouble
catching the SocketException, it is showing a phone generated disconnect
notice that I am trying to catch

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

I am writing a Bluetooth driver and am trying to implement auto reconnect, I
can sucessfully connect and disconnect. I want to have the application auto
connect if the connection is dropped. I have listeners that raise events for
open
 
streamConn = (StreamConnection)Connector.open("btspp://" + address);
 
but once the connection is open how can I detect if the connection is
dropped? I could add a exception handler on read() but there could be a
valid exception and I can not assume that an exception is a dropped
connection. Is there a way to detect if the StreamConnection is closed?
 
Thanks
