Finally got the time to solve my bluetooth project!
Got the client running on both computer and cellphone ( HTC P3300 ).
I do now send text to\from both devices, this enables
me to make a nice remote control for my winamp.
The library i use is this one : http://www.codeplex.com/32feet/
shared-source project to make personal area networking technologies such as Bluetooth,
Infrared (IrDA) and more, easily accessible from .NET code. Supports desktop, mobile or embedded systems.
The project currently consists of the following libraries:-
- Bluetooth
- IrDA
- Object Exchange
I ported one of the sample codes that was in VisualBasic to Csharp (The pc client).
Next up is to port the windows mobile client also.

Just a little update:
It now works with Winamp, much easier to code then i thought..
Here is a screenshot of all 3 apps in action:

So, yesterday i ported the pc client, today i ported the windows mobile client to csharp also, now after hours of swearing it finally works!
I can now send strings each way, to\from pc to\from mobile phone.
I did some easy tests yesterday for catching the strings as commands, this works great!
So now I'll design a better UI for the mobile client.
Screenshots'll be up soon.
So, as you probably know i use Csharp, after some google i found "Winamp SDK .Net", perfect! this one enables me to control winamp directly, withouth hacking with "Sendkeys".
This SDK can be downloaded here :
http://sourceforge.net/projects/cswinampsdk With this SDK it took me half an hour to complete the framework for my application.
All the basic "player" functions is working, next is to integrate the playlist, so that i can browse songs and choose
to play them on the computer from the mobile.
