Bluetooth client/server communication between computer and mobile phone

Question

I need just a basic example or tutorial of making a mobile phone and a computer communicate via Bluetooth.

A good link/website to start from is also appreciated.

Server part (computer part) can be made on many programming languages (Java, C++, Python or even something else).

Client part (mobile phone) must be a Java Micro Edition MIDlet.

Answer 1

After long days of research, I managed to make an application that sends (in real time) screenshots of area around mouse cursor to mobile phone client.

Both client and server were written in Java. I used BlueCove to make the server part. BlueCove is JSR-82 implementation, so server and client code were quite similar.
