Dan, it's probably easier than you think (for the right person).

Stratux is entirely open source - it should be possible to gin up whatever data the FLARM-in wants. I sent you a couple links about this in email: The Flarm data protocol and how to get serial output from the pi.

As an IT manager would say ... " just a simple matter of programming ".

For me, I'd just let the weather information fall onto the cockpit
floor.* I don't see the utility, for my type of flying,
of having weather information displayed in my VFR glider cockpit.*
I'll continue to look out the window for that.* ;-)

Dan you are wasting your time trying to get these to talk together, as I have already mentioned (in this meandering thread). XCSoar accepts Flarm dataport format data (including FLARM, ADS-B and PCAS data from a PowerFLARM). Stratusx outputs GDL-90 format data. They are not compatible at all.


Might it be possible for someone to write a Raspberry Pi program to convert GDL-90 data to Flarm data port format? Is GDL-90 proprietary? Do you have to pay a license fee to use it or something? Since it's ADS-B generated data and Flarm outputs ADS-B targets from its own receiver I would think it would be relatively straightforward for a competent programmer to do. You might even be able to plug the Flarm serial output directly into the Raspberry Pi and Mux the two data streams together for output to a flight computer.

That still leaves the question of how to handle any ADS-B weather (especially weather radar) information, the display of which presumably no soaring flight computer maker has provided for yet. However, LXNav is rolling out their own cellular data-based weather map service. If that's not a proprietary/closed format some additional work somewhere could allow making ADS-B weather data suitable for display as well - at least on some displays. Cellular data feeds can be problematic for technical and regulatory reasons so using the ADS-B free weather is ultimately probably a superior solution - just in the US. Satellite subscription could be useful elsewhere I suppose.

Just spitballing - I'm no expert on this. Would be cool if it could work though.
