Sure, if you'd like to send us your device I would take a look at what it's outputting. I've heard nothing about this support for GDL90 on Sentry though.

Hi Tim,
Time goes by and it looks like Foreflight has decided to provided a generic GDL90 for it’s Sentry Plus. And it works already jointly and fully supported together with some other 3rd party tools (i.e. the ADL Golze iridium weather box).
So I habe tried to connect my Sentry Plus with Skydemon via GDL90. Result is that it properly gets connected to Skydemon even if I use the Sentry Plus in WiFi client mode (what is cool), but Skydemon stucks in “searching for satellites” even the Sentry Plus shows a position fix accuracy of 2m and less.
So it looks like either the Sentry Plus GDL90 implementation is crap or the Skydemon one.
Would you mind having a look?

Cheers
Talisa

Technically there is no reason of course, but Sentry is a Foreflight product, regardless of who manufactures it. They have the option to keep it to themselves and they have chosen to do so.

Sentry is a Foreflight product, designed to work only with their app. Other apps are not able to use it.
