So a few weeks ago I got my ArduStation in the mail. Since it is no longer supported under ACM2, I decided to rewrite the code to support MAVLink. So far so good. You can start and stop the MAVLink data feeds and monitor flight data. I'm also looking into the thing's ability to show some basic graphical HUD displays (although note that there aren't pixels between characters or rows (bummer)). I only have 9600kbps Xbees (9600 xsc). So one thing I've noticed is if you get the data rate too high the pipe becomes clogged and you can't stop feeds. Is this an Xbee problem or a ACM problem?
