[Help-gnunet] Seaching for example project

[Vincent]

Hi,
is there an easy example project somewhere in the internet I can use to
understand gnunet developing?
Just some easy messaging between peers.

Or some project that uses gnunet on openwrt or lede?

The only thing I have to do is to simply pass messages to the other
peers. But somehow I don't get the api. ^^
And I like to look at example code...

Thanks. :)
