What steps will reproduce the problem? Run a pybluez server script and try to connect to it with a J2ME midlet.

I have written a midlet and tried it on various phones and have come to the conclusion that it works on Nokia 6230 and Nokia 5610. Various Sony-Ericsson phones do not work (they don't even connect to the server) and neither do some Nokia's (9210). They do, however, connect to a java server, so I guess the problem lies in pybluez.

I'm running pybluez 0.15 on Ubuntu HH.

That's jumping to conclusions a bit quickly...

What does "do not work" mean? A service search fails? Device discovery fails to find the phone? Service search succeeds but connection initiation fails?
