Hi Marius,

> On my Handy I'm programming the Client in Java unsing JSR 82. In my Application I can find the Linux Device, but if I'm scanning for services (RFCOMM) there will be found no services!
> If I scan my Windows Laptop with the same Application, there are many services. Like this:

you need to register a SDP service record for your server. Example for
this can be found in pand and sdptool.
