I am having problem with upload command from flight data. Eg Change altitude, restart mission ect. I do not have this type of problem with the previous Mission Planner. When I try to change altitude, a fail massage window appear. I also can not write param to APM while flying. But if the plane had landed and close by my computer, there is no problem. Anyway I can establish connection between the two data modem with ease.
I'm using RDF900, am I doing something wrong in 3dr radio setting ? Thanks for your help.
