Sitting at home doing these tests...
At first, the Android tablet (Samsung Galaxy Tab S) did not automagically rescan wifi's near it. I had to go into 'settings' and select the actual wifi from the freeflight. iFly still did not connect, so I powered down both, then powered them up again, freeflight first. (In the plane, of course, the tablet will be on first. Still working on that one.) Found out that freeflight uses a set ip address of 192.168.10.1 and after connection, the tablet ip was ..10.2. So I knew it was working at the OS level. Started up iFly and voila, they connected! Hoorah.
One new question, though. When I set range to unlimited, I still don't see the airliners on the iFly screen even though I know the ads-b unit is reporting them. (From previous experiments, most of them are about 200 miles away around the Memphis hub with an occasional overhead one.
Note: At home, I'm too far away from an ADS-B tower to get the good stuff like weather, 948UAT, and so on.
