The Skydroid Tower app did upload the full 400+ waypoint file successfully. It was very slow and there is no progress indicator, but it eventually announced that it was successful. I then downloaded in Mission Planner over my 3DR radios and saw that all waypoints were present.
But, in Mission Planner, just simply receiving normal telemetry, I have a ton of lost packets happening. (You click “Stats…” in the upper right of the screen to see.). I posted about this and posted a short video at Errors uploading missions. So, how do I get support on this type of thing?
Is anybody else using the M12L with Mission Planner who can try this?
