No you don't need a GPS chip. If the mobile device has no GPS, Follow Me function as well as current RC's position Homepoint will not work, but you can still fly.From what i have read the iphones and ipads that have cell service also have the gps chip. Not required to have service just needs the other chip. f
Yes. I do the same as you. Sometimes technology can be idiosyncratic.There's a Youtube video that talks about this problem, and it's published by Drone Valley. My thought was that it really doesn't matter why. The hard fact is that it won't so I use an iPhone 7+ instead, and it works fine. It's not a dedicated device, which would've been nice, but it solves the problem. The iPhone 5 will be used by a grandchild instead.
Here's another problem that I've stumbled upon. During the boot sequence, I must turn my drone on first, then the RC. If I do it in reverse like the manual suggests, the RC and phone won't connect. Has anyone else experienced this problem? The phone is the last thing to be turned on.
