Hi Rob,

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

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.

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

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.
