Re: device connection detail?

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.

Addendum:

At home, when the tablet is powered up first, it defaults to the home wifi. In the plane, it defaults to the airport wifi. So it looks as if I will *always* be required to manually scan for the freeflight to be able to connect to it.

I guess that is ok, since the tablet is used with the Internet far more frequently than it will be the ADS-B unit.

You can go into your tablet's settings, then WIFI, and tell it to forget the airport WIFI.

Re: device connection detail?

From watching the behavior of my Nexus 7 I think it does the following on waking:

Connect to the SSID that it was last connected to, if none then

connect to the strongest SSID that it already knows about, if none then

wait for the user to select an SSID.

There is a handy app called "WiFi Analyzer" that will show all the networks that the device can hear and their relative strength. The strength is actually given as absolute, dBm, but i doubt that it is too accurate.

There are numerous potential reasons for this failure. Do you have another App that also connects up to Free Flight to serve as a 2nd data source for comparison? If the other App can see these airliners, but iFly cannot, then it should be iFly fixable (as either it's a software bug or operator error of some sort, or a mix).

But if you can't see the airliners from the other App either, then the issue probably can't be fixed by iFly.
