Problem with UDP packets

Hello Peter

I know what you mean but for me it's very hard to find out how it work.
It's the first time I'm doing such thing with the arduino.
I know nothing about programming language(c++) and network on the arduino.

I've worked with it a few years ago at school but it was just a few simple steps.

And now I'm working on a project with it and I have not so much time create it.
And you guys know what the problem is and It's very easy for you because you have a lot of experience with it.

For you guys it take just a few seconds to show it to me, and for me it will take a lot of tile to find out.

That's the reason why I'm asking these (simple) things to yours.

I hope you want to help me further.

Thanks a lot

Leon
