I had a problem:

1- the built-in combo Wifi / Bluetooth card of my netbook wasn't compatible with Windows XP Bluetooth stack and

2- the supplied Bluetooth stack was incompatible with my fischertechnik Robo TX controller

I found a (if not the) solution: the BlueSoleil software is the only one able to manage everything smoothly.

On top of that, the development team is very responsive when there's a problem.

Highly recommended!
