I need to set up two Arduino boards to sense when they get close to each other and display this “signal quality”.
So, my first idea was to use XBee modules… which so far has proven very complex…
In the first iteration of the project I don’t really need to send any information between the units… the only thing they need to know is how strong the radio signal is between them.
Is there an easier way to do this without getting in to “communication” at all? Like broadcasting a sine wave or noise or something?

If you use the XBees series 1 with the wireless serial port software, they behave as does a “Hayes” type modem with AT commands. Very simple.
IEEE 802.15.4 defines “LQI”, a link quality indicator available in every '15.4 module.
I just managed to get a network up and running with the new 2.5 XBee’s using the transparent mode.
I’m new to hardware… so I don’t quite understand what you mean with every 15.4 modules… ? All the data I send into one XBee apears on the other side without any extra data so I assume I need to get this from another pin? There’s one pin that’s supposed to output a PWM signal of the link quality. Is this what you are referring to?
So far I’ve not been able to clock this… it’s seems like it’s always HIGH…
Thanks!
