Hey guys, I am building UAV which sends video through a RPI and then through a long range WiFi link alot like what this guy did Here. Anyway I am trying to find out how you can send the telemetry data from the Audrupilot through the RPI and hence throught the WiFi link and then to Mission planner where it then can goto an Audrino Uno controlling a antenna tracker. Now the guy that I linked before did mention briefly how he setup his antenna tracker but it was quite confusing and the links were broken. The thing I really dont understand is how the telemetry data gets from the GPIO to the mission planner.
Anyway has anyone personally done this before, and do they have any good tutorials to follow or just to get me started in the right direction.
