Can't find my phone with bluetooth dongle

Hello,

I have bought a blue tooth dongle to connect my laptop to my phone (Nokia 2680 Slide).

If I use the search funtion of the bluetooth software I can find all kind of hardware, like laptops and cellphones. But my own phone is not found in the list. I have activated bluetooth on both devices (I'm not an idiot :p), so that is not the problem.

The weird part is, the first time I tried it, it totally worked fine. But now I keep trying and trying and I can't find the phone.

The phone is brand new so I don't think their is any kind of thing broken in it.

Anyone has any hints?
