I have an iphone with ar. freeflight installed on it. when I try connecting to my parrot ar. drone 2.0 it often takes 20 minutes just to connect. I've tried switching it to airplane mode after connecting to the drone wifi, as I've seen suggested, but it still seems to take a long time for the pilot options to become available in the app. does anyone have any tips for getting the piloting available quicker, it pretty much drains most my battery just waiting for the app buttons to become available.
