XBee 868LP modules

Hi guys.
I’m trying to create a little network:

  • several remote devices sending data to central unit
  • central device collecting data

I’ve bought 2 XBee 868LP boards and I followed instructions to make it communicate.
It works, but only for 2 devices (using development board).
Now I would add a third device to simulate little newtork but I’b confused about do it (transparent mode, API, DigiMesh…).
Anyone using these modules?

Thanks.

Anyone using these modules?

No, but if you post a link (NOT just a URL), I'll take a look at them.
