Thanks for working with me. The mobile device (tablet) that I’m using…and you’ll love this…is a Chinese IBOPAIDA tablet. This will require some explanation. There is a bit of a parallel control going on here with my neighbor, Jim. He is an electrical engineer and and hobby computer science guy. He has a P3 Pro that’s been sitting on a shelf for years. When I got my drone I asked him for advice on buying a tablet. He said that in trying multiple tablets with his drone, the only ones that worked were the ones with cell phone capability, even without SIM cards. So he steered me to AliExpress and we looked online for tablets. He came across this tablet, on sale, with deluxe features (great screen, lots of RAM and Memory for a tablet, really nice and fast quad processor, dual SIM card capability, etc, etc.)…$148 and free delivery. He bought one too and uses it with his P3 Pro with no issues at all. It appears to be Android 8.1. I just connected my RC to the AC in the kitchen and could not find any firmware info from the AC. Again, the AC signal icon is dark and the status window reads “Disconnected”…but it’s ready to fly.
