USB or RS-232.

The issue with GRT via USB is what chipset is used. I know they are compatible with more than one but not sure if all. Connecting via RS-232 should not be a problem.

If the output format is the same as DUAL, iLevil, FDS and SkyRadar, then I suspect the GRT systems will be fine as I have tested all of those.

This is all well and good, but how do you go from a usb output on the Raspberry PI, that thinks it's communicating with a WiFi dongle and strip out the data string to feed into the RS232? I'm not a computer guy at anywhere near that level, and there's a lot of missing links here to me.

OOOPS!

I missed that part of the dialog.
"My Bad".

Was thinking there was a serial stream out the USB port.

The communication mechanism - USB, wifi, Bluetooth, serial, light signals, semaphores, or smoke signals - isn't the real challenge. Internal to the code, it's just strings of numbers and characters. These strings can be transmitted on any of the methods with relative easy.

The challenge is knowing what format the vendor is expecting. It's a bit like communicating in another language. If you are speaking French and the other person only understands Chinese, not much useful gets conveyed.

The contributors to this project are using a combination of published documents and packet sniffers to figure out what is expected. For some of the target vendors, they don't publish anything, so it's a lot of difficult reverse engineering. For some vendors, there is no available Rosetta Stone.

I know there is a desire to mimic other ADSB receivers but the contributors to the project don't own the necessary original manufacturer hardware to aid with the analysis to black box engineer the packets and messages. If someone wishes to donate hardware, I'm sure it would help.

Hi Charles, v0.1r3 is the best so far. However, like much of our latest avionics, you should keep an eye for updated builds. I am aware of a number of bug fixes and features that have not yet been rolled up into a new build.

UPDATE: a newer "release" is now there. Rather than keep editing this post, I advise taking the newest build. If you have any issues then back off the the newest "release".

Default Stratux is getting better

For those who are interested, there is a now a subgroup over on reddit dedicated to the Stratux project.

A few highlights to pique your interest ...
  • Improved more stable code
  • Web configuration and status
  • GPS support
  • AHRS testing
  • 3D printed case

It's been tested with the following functionality:
  • ForeFlight 7.2 - weather, traffic, AHRS
  • Naviator - weather, traffic, AHRS
  • WingX - weather & traffic
  • Avare
  • iFly 740 - weather & tragic
There is a standard parts list. It really is plug-n-play if you use the list. There is also a lower cost SDR (saves $10) the same specs as the original recommendation.

Follow the progress on reddit: https://www.reddit.com/r/stratux
Watch for new builds on GitHub: https://github.com/cyoung/stratux/releases

Ordered parts ... Can't wait to try it out

Default I tried it out!

So I couldn't resist and had to order it up. I have an RV-6 with a Dynon Skyview system in it. I have ADS-B out and a Dynon ADS-B receiver that I spent $900 on, I think. I also have an Ipad in the plane running ForeFlight. So I got the parts, assembled it, and had it up and running in about 15 minutes. I opened up foreflght on my Ipad and found the stratux device right away. I couldn't wait to try it out in the air. I went flying today and was amazed. The thing got weather and traffic exactly like the Dynon Skyview. The ipad actually displays traffic a little nicer I think than the Dynon does. There wasn't much weather around but what little there was matched on both screens. The only thing I noticed was on the return flight The traffic was not showing altitudes? On the first flight from Long Island to Connecticut I saw all traffic the same as the Dynon did, showing altitude in relation to me. On the return flight all the traffic had zeros instead of the altitude in relation to me? Weird, I flew again and still zeros. Have to figure that one out, but so far the stratux amazed me.

Hi Richard, thanks forcthexPIRE.

The "zeros" is a bug.

You can read a similar report and reply on reddit -
