I have 3 apps on my phone that use the USB OTG feature to receive the ADS-B data from a SDR (one of the cheap ones). Avare, FIS-B Free, Avare ADSB Pro (different developer than the Avare above). There are Android solutions out there. Avare would be great but I can't get the USB OTG function on my Nexus 7 without rooting it (other Android tables work very well though).

Dave,

Very cool!

The few attempts I've made to hook devices up over OTG cables have been hit or miss.

I've gone back and edit my original comment. Thanks for syncing up our thread!

Not too concerned with Foreflight, since I left ios a while back. :-)

Does your answer mean that it *is* (or might be) possible for the stuff running on the pi to get ported to an android device (the same one running Avare or other mapping app), instead?

And I don't really consider this a 'learning curve' any more. The last time I programmed, 'Basic' meant Basic Assembler Language (BAL). At this point, the gap is far to wide. I'm just grateful that you and other users of various technologies have discovered 'open source' and its variations. I'll try to take advantage your knowledge on this, and hope to pass on my knowledge of some other field.

Hi Charlie,

I've put my foot in my mouth so many times on this read I may as well skip dinner!

So I'll attempt to just answer you question and not go off the rails.

Is it "possible" to port the project to Android and connect it with one of the Android based aviation navigators? yes. Is it easy? no. Is it likely? no.

Well shucks. Guess I'll have to spend the extra 50 bucks to save the 800 or so vs ADSB...

:-)

With all the back and forth, what do I need to buy to make this work. I am interested since at this time, I can not buy a $800 Stratus and this would be great for foreflight. I have looked at Amazon and it looks at though the grouping everything for $100. After reading, I am confused if there are other items to buy to make it work better.

Thanks,

The reddit list looks complete for the Stratux for "weather only". You will use the battery USB cable to charge and then switch it around to also to power the RPi.

There is a follow on project underway to add GPS support and to support simultaneous weather and traffic. Nothing you buy now becomes obsolete.

You will also need to have or borrow an SD card reader. You computer may have an SD slot or you may have a USB card reader that an supports SD card. If neither, then the "thing" you are looking for is something like this: http://amzn.to/1U3d7Po

If you get all the pieces and get stuck, I'm happy to get on the phone (or Skype) to walk through the process.

I was receiving traffic of some flavor with the recommended setup. (See my 2nd post on page 4 of this thread.)

I was connected via bluetooth to a GDL-39 for my GPS position source but Foreflight was showing Free Flight via the Stratux for the ADS-B.

As I understand it the GDL-39 will not send ADS-B data to Foreflight at this point.

Thanks,

The current version has full TIS-B traffic and FIS-B weather, the recommended hardware is:

http://amzn.com/B00P2UOU72

Then follow https://www.reddit.com/r/flying/comm...ght_or_pretty/

Most people report it takes about 10-15 minutes.

Thanks okei. Many people - me included - get confused by the various traffic data being processed via ADS-B.

The reddit thread has a few comments trying to clarify what is available with the Stratux.

Right now I've only tested weather and 1090ES traffic. Unless you buy two tuner dongles, you pick one of those because it can only pick up one at a time.
...
You can get traffic data with just one. GA planes with ads-b out would transmit their data directly to you on 978 ...

To further confuse the traffic question is that a number of GA aircraft are on 1090 rather than 978, especially EAB aircraft.
