Hello all,

I am trying to connect BlueZ with JSR-82 with RFCOMM sockets. The BlueZ 
server creates a socket server and the JSR-82 MIDlet connects to it.

It all goes well until the server sends some data and closes the socket. 
The JSR-82 program launches a "java.io.IOException: Stream closed or 
disconnected" when trying to get the number of bytes available from the 
stream. The problem can be solved by having the server call sleep(10) 
before calling close(clientSocket), giving some time for the client to 
fetch the data, but obviously it is a bad solution.

This is the code:

Server, C:

    status = write( clientSocket, message, messageSize );
  
    sleep(10); //Comment this for an error

    close(clientSocket);

Client, Java:

    try
    {
           while ( inputStream.available() == 0)
           {
                Thread.sleep(100);
                notifyUser("Waiting for data...");
           }
    }
    catch(IOException ex)
    {
           notifyUser(ex.getMessage());
    }

Rest of the code is not relevant in my opinion, but I can post it if 
someone needs it to find a solution. However, it is pretty simple and 
based in http://people.csail.mit.edu/albert/bluez-intro/x502.html and 
http://developers.sun.com/mobility/midp/articles/bluetooth2/

Is there something I am missing about RFCOMM sockets? Is it JSR-82 
related? Is it a bug?

Thanks

jm
