Just got PFLARM going with a nexus10 using butterfly to Wifi to it.
Seems good so far, Flown once for a short flight. Spotted a couple of gliders (green plane shape showing direction with height next to it +3.5 for example) also commercial into luton (ADS-B) presumably.
Yet to see any mode S or C displayed.
Of course it will be the non transponder plane that hits me out of the blue.
But so far impressed.
Using a LX avionics PFLARM core brick in a Europa. Just needed power to install.
I tried to find information on what to expect on the display but couldnt find any info.

If SkyDemon cannot connect to your PowerFlarm, then you cannot enter the PowerFlarm Go Flying mode. Only if a connection is successful (whereupon SkyDemon will receive GPS and contact data from PowerFlarm) will SkyDemon enter Go Flying mode, assuming you are initiating the connection from the Setup -> PowerFlarm menu.

I have it working now. I got the nexus to find the butterfly connect WiFi first and then skydemon setup pflarm go flying. With it active, skydemon takes the GPS feed from it as well as traffic data. A couple of times I lost gps and the only way to recover was to restart skydemon, a bit tricky while flying. Maybe I need to look at the GPS antenna positioning.
