Just started playing with the IFD100 app. My plane has an IFD540 with dual Aspens so I've never really needed the IFD100 but my daughter just bought a Cherokee 235 with an IFD440 and steam gauges. Looking to do dual Aspens there too but for now trying to figure out the iFD100. We were flying today and saw traffic on the IFD440 and Foreflight but never saw it on the IFD100 app. The configuration is:

IFD440

STEC55X

GTX 330ES

GDL88

JPI EDM900

All other functions of the IFD100 seemed to work fine. We couldn't tell about ADS-B weather. It was another beautiful day for flying here. Anyone have a solution to our issue? I did note tonight, after watching a video about configuration that I did have the IFD100 app mis-configured to be a IFD550 instead of the IFD440. Wifi ADS-B support was also off but I understand that is only used if your source is via wifi.

With your configuration, you should be seeing traffic from the GDL88 on the IFD100. Any chance you had an active "Config Modified" message on the IFD100? If that's the case, a hard restart of the IFD100 is required. Try again on the next flight and if it doesn't show up, we can take a look.
