Hello !!
i have got two xbee s2b with xbee pro shield like this :


then i have asked here before about how to communicate between each other and some one guide me to this tutorial

and i doing it step by step correctly but it's doesn't transfer the data between them.

My question about is :
should i configure the two xbee modules before i'm using it?
and can some one tell me how to configure it under linux OS (fedora 20).
because i haven't windows now and this task must be delivery to my prof after 10 hours from now.
just i need guide

Only if you want them to talk to each other.

and can some one tell me how to configure it under linux OS (fedora 20).

Install Wine and some version of Windows. Then, use X-CTU. Or find a friend that has Windoze.

because i haven't windows now and this task must be delivery to my prof after 10 hours from now.

Sorry to say, but you are screwed.
