I am trying to enter Flight Data mode to get the .DAT files. I am doing all steps as per instructions powering the TX then the P3 and going into Advanced settings in the GoApp. When choosing Enter flight data mode I am getting an "MC Data Error" message and then the yellow window saying that I am in Flight Data mode but after connecting my P3 to my Mac it is not connected. I never had any MC Data Error warning as long as I have the Phantom. Any ideas why is this happening?
