timeout error

Hi,

I'm trying to make this project, the Altastation http://en.altapix.com/technique/altastation.html

It sends flight data from the the aircraft to an LCD on the ground.

I am using two Xbee Pro 2.4ghz units to communicate between the aircraft and the groundstation. The LCD shows the sketch starting when I power it up, but then it gives me an error, "D: Frame Timeout" and doesn't go any further. If I plug the Arduino directly into the aircraft serial output (eliminating the Xbees) then it all works fine and the flight data is displayed. I assume the Xbees are causing this error. I have played around with the Xbee settings for days. Any help would be much appreciated.

Thanks,
Julian

What sketch?

I am using two Xbee Pro 2.4ghz units

What series? How are they configured? Do you KNOW that they communicate with each other?

but then it gives me an error, "D: Frame Timeout"

That's something your code is doing...

If I plug the Arduino directly into the aircraft serial output (eliminating the Xbees) then it all works fine and the flight data is displayed. I assume the Xbees are causing this error.

No, the XBees are not. The incorrect type of XBee, maybe. Mis-configured XBees, possibly. XBees out of range, maybe.

Too many unknowns to help you now.
