I am getting confused about what I need to use ground station with my p2. I currently have iosd, h2-3d, gopro3,fat shark fpv, and have ordered the btu (maybe prematurely ). I downloaded and installed ground station on my iPad mini. I am finding all kinds of info online about how to do this, but most seems too be contradictory or for setups that differ from what I have. Can anyone direct me too a set of instructions that would work with the above configuration? ...or have I bit the wrong bone?
