Well I got it working, I think. I vaguely remembered, that when you got the app key from DJI, they asked what the package name was. So my package name isn't the same
as drone mission. when i changed the drone mission package name, to my package name, it worked. I'm getting video and telemetry now. I can't fly now because it's
nighttime, but I'll test it tomorrow morning to see if the altitude and distance limits are gone.
