Hi Jean-Marc,

As far as I can see, it is not easy to build a RF circuit from the scratch.
It usually requires a lot of trial-and-error. So I prefer off-the-shelf
modules. Currently I'm testing two different modules:

One is based on the very popular Nordic nRF24+ chip (around $5)

I grabbed mine here

The other one is Microchip MRF24J40 module (around $9)

I think major distributors carries it. You can do a search here:

Thanks
