Development of an application to be deployed on a Nokia 770 PDA that would "control" another machine, basically what a mouse does to your machine at the moment. Whatever interaction is done by the mouse can be seen on the screen. The PDA would be the mouse and nwould establish a connetion with another computer via bluetooth, and the interactions on the PDA would reflect on the screen. I have installed Fedora Core 6 as my underlying OS. I have set up my IDE, Eclipse with the Laika plug-in. I have installed CDT, Scratchbox and Maemo rootstrap packages. The BlueZ packages are already installed. After that I would need to code (in C) so that whichever coordinates is passed from the stylus (mouse stream) would be transferred from to the other screen via  bluetooth. How do I establish the connection via Bluetooth? By using BlueZ or the D-Bus API?
