I am a newbie and really confused. I have a newer vision 2+, iPad vision app, DSL app all with the latest upgrades. My question is I keep seeing people on this forum talking about buying extra hardware to run ground station and at the same time they talk about simulation practice. Can I just use GS in the vision app and not have to buy extra hardware? What would I need to do to use the GS app. Lastly what is the difference in the two apps if any and where do you find a manual for their use? :?: :?: :?: On further reading I did find a post that the iPhone/iPad DJI Vision app works out of the box -no additional software or hardware needed. Is this correct? If so, I only need information about the iPad DS app.
