Yes that is what I meant by connected.
You shouldn't need to go flying to see traffic, unless you are a long way from any airline routes you should see something at almost any time of the day or night.
Unless you are sure that you do not have metal coated windows take your PAW outside to give it a clear view of the sky.
Then go to the 'Traffic' page on your PAW and check that your PAW has a table of aircraft visible to it. If that is good, then fire up SkyDemon on the tablet.
Now to to the settings (the gear thingy)>Navigation Options, and scroll right down to the bottom. In the section'Show other Traffic', set the 'Show within Vertically' to something silly like 50,000ft. While you are there select 'Show Bearingless Targets', though we are not testing this at the moment.
Close the settings window, then Click 'Go Flyig' and select 'Use FLARM'.
Once SkyDemon has found the Satellites and displays your position, zoom out to see a fair bit of the country. You should see the ADSB traffic that was in that table.
