Some ADS-B issues my first time using AvareX in the plane

[barry speronello]

Today's flight was my first opportunity to use AvareX in the plane with my Dual XGPS-170 ADS-B receiver, and there were some issues that came up.

The first was that a steady stream of errors (exclamation point in a red circle) throughout the whole flight  The majority were due to one or both of the following:

a) Notice

Unable to download NOTAM:
ClientException with SocketException:
Failed host lookup: 'rfinder.asalink.net (OS Error: No address associated with hostname, errno = 7), uri=https://rfinder.asalink.net/avionet_run.php

b) Notice

Failed to download weather from Internet.

AvareX indicated that it was connected to my XGPS-170, and all the normal lights showing the receiver's proper operation and communication were present.  But it seems like AvareX was looking to communicate with the internet as well (and failing).  Unlike Avare, I do not see a setting on AvareX to select whether ADS-B information is to be received from the internet or an ADS-B receiver.  What am I doing wrong?

The other issue was that AvareX showed very little traffic in a region and at a time when there are never fewer than a dozen traffic markers on screen when I use Avare (or any other traffic-capable EFB app).  There would be long stretches when AvareX was showing no traffic, then one or two would pop up and then quickly go away.

Any ideas what's happening?

BTW, I switched back to Avare for the flight home and the traffic display was normal.

The level of ADSB traffic displayed is an issue that several of us have had with AvareX vs Avare, but despite requests for it to match either Avare's level, or for providing the ability of the user to adjust it to the flying environment, and comfort level they desire, no change has yet been made. Maybe one more user request will help encourage the developers to make that modification.

Thanks for adding your experience in support of that.

Is AvareX now compatible with BLUETOOTH ADSB-In?

Hack a one year countdown timer if you wish  Avare platform growth.

There are two roadblocks- 1- Apple is enshittifying iOS and I forsee both app and device issues and high contact time dev team issues- ie full time job.

2- AvareX multiplatform coded is neither Avare legacy vibe nor Foreflight vibe.  Definitely odd to this Andtoid bias GenX Avare legacy fanboi who works in the airlines with iPad Jeppesen EFK like most.

If you want to sell, your market will come as the new owners milk Foreflight dry.  Pick a final vibe and alsi consider your new user- the bilked Foreflight fed  up with higher costs, less responsive teams, etc- corporate enshitification.

I hoped Avare X would have matched Avare Legacy by now, for me, I don't see it.  You could charge/ more for Legacy and I'd happily pay for it.

I totally agree.  Avare Legacy was/is hard to beat. 

 

Just a quick note to Avare Legacy users.  I had a problem Saturday where I could not get any ADS-B traffic to load.  Somehow, The old I/O program, which was still on my tablet, was running in the background, which blocked Avare from picking up the signals.  Anyway, make sure that old I/O program is uninstalled so that doesn't happen to you.

Any thoughts about the other issue of error messages relating to downloading weather to the app?  One seems to be saying that AvareX is looking for weather info from the internet even when it is connected to an ADS-B receiver via bluetooth (IIRC, the tablet's wifi was off during the flight).  The other seems to be a failure to download Notam information, but with a much more detailed and complicated backstory than the weather message.

[barry speronello]

I was looking through some other threads and found one that may be relevant to this thread.  It was another user of AvareX having problems with ADS-B traffic.  That user was asked if they had another app on their device also connected to their ADS-B receiver, because for ADS-B to operate properly in AvareX it must be the only app using the receiver's data.

In my case I did not have another app on my tablet, but my wife had a separate tablet running AvareX and set up to be connected to the ADS-B receiver by bluetooth.  I have no idea if hers was receiving and displaying traffic and weather, or had any error messages.  I didn't take the time to check on what it was doing, and my wife did not know what to expect from the app (so she had not frame of reference to judge possible flaws in its performance).  So she did not comment on it.

Should 2 separate tablets each running AvareX be able to connect to the same ADS-B receiver by bluetooth?  If not, could that have been the source of my problem?

[Apps4av Support]

Will fix in next build.

Is there a reason to avoid an options menu in AvareX? Being able to customize the user experience on legacy Avare was great. The sliders are useful but not everything works well with sliders.

Thanks.

[Apps4av Support]

Options are not bad but having all of them in one place is a bad UI design. There needs to be connection to the feature it's modifying

• Not having options is worse than a bad UI design
• Bad UI can be iteratively improved now that the AvareX basic architecture has been established and the guts seem to work well
• I think the opinion of the majority of your user pool of AvareX users want options and they want them collectively located in an options menu.
  • I constantly see requests for options & customization at least to the extent that legacy Avare allowed.
  • I don't think any user disagrees with the development team that good UI design is important
  • I think most of your AvareX users are already above-average for device technical skills if they're running their EFB on an android tablet or Windows device (not your average foreflight child of the magenta line)
  • The handful of people I've talked to who have tried AvareX fit this bill and most of them want more options and want those app options to not be stuck in awkward initial app setup swipes.

Thanks,

Dan

Today was the first time I had a chance to fly with the newest AvareX update (0.74), and it still behaved much the way I described in the original note in this thread.  AvareX showed almost none of the heavy traffic in the area, and produced error messages that as far as I understand them indicate that it was unable to download Notams and at least some other FIS-B information.

First I set up a connection between the XGPS-170 and AvareX on my tablet (AvareX traffic range set to L).  It operated that way for 5 minutes in an area with 4 ADSB towers and lots of traffic.  In that time it displayed between zero and 3 aircraft.  I took a screenshot (attached to this note).  I then power cycled the XGPS-170, stopped bluetooth on the tablet, and established a bluetooth connection between legacy Avare on my phone and the XGPS-170.  After 2 minutes the screen was chock full of traffic (screenshot attached).

I allowed AvareX to continue to run and it showed a number of the red circle with exclamation point error indications.  I expanded one of them and took a screenshot (attached).

So either I continue to do something(s) wrong operating AvareX, or a problem remains with AvareX and traffic (at least when connected to an XGPS-170).  Similarly, either I am doing something wrong re. FIS-B, or there's an issue with AvareX downloading at least some of that data.

Thoughts?

[Apps4av Support]

Barry thanks for sharing. Will compare the X code with legacy code.

And seems like you are trying to get Notams when you don't have Internet. That won't work. Maybe the warning needs to be adjusted to not show when there is no internet.

Have updated to v0.77.  Will test as soon as I can, but with the holidays and poor weather this coming weekend, it won't be earlier than next week.

One question, though.  The "What's Changed" entry for v0.77 is "added missing traffic from 1090".  That sounds to me like the code has been changed to capture and decode extended squitter 1090 mHz ADS-B signals directly (which it had been missing previously).

If that is accurate (or even close), then I'm not sure that it will help in my situation, as the XGPS-170 only receives ADS-B data over 978 mHz.  It can't get 1090 mHz data directly from another aircraft.  It's of data on1090 mHz equipped aircraft comes indirectly from ground stations via TIS-B rebroadcast.  The XGPS-170D is the version that can receive over both 978 and 1090 mHz.

So, the question...should I expect the changes made in AvareX v0.77 enable it to read ADS-B traffic data either received directly from aircraft equipped with 978 mHz ADS-B out radios, or  indirectly as ground station rebroadcast of data from 1090 mHz equipped aircraft?

[Jeffrey Ross]

Sounds like you need ADS-R.

Since you can only receive UAT in you need the ground stations to rebroadcast the 1090 traffic as 978mhz (UAT).

In order for the FAA to do this your transponder (must be ADS-B out compliant) needs to send a code to the ground stations that you can only receive 978mhz in.  The FAA will then rebroadcast traffic to you within a 15mile radius and +/-3500ft of your position.

Better solution get an ADS-B receiver that receives both 978 & 1090.

When the 978 only 170 was still newish, the app ADSB receiver app by HIZ LLC came out.

A $12 SDR and antenna later, one could see 1090 traffic on USB dongled SDR AND bluetooth 978 traffic and weather.

Use a $12 powered USB dock and it'll charge your device and run the SDR.

A bit cumbersome to kit vs a dual band ADSB receiver.

[barry speronello]

Jeffrey, with my 1090es ADS-B out transponder configured to tell the system that it receives only on 978 mHz, it works perfectly well receiving 978 mHz ADS-B out broadcast directly from other aircraft equipped with UAT (978) ADS-B out radios, along with ground station ADS-B rebroadcast of position data on 978 mHz showing the location of aircraft with 1090ex ADS-B out equipment.  It's one of the configuration options built into the system.  It doesn't require any additional equipment to show all ADS-B out equipped aircraft in the vicinity.

It does, however, need the EFB software used to display the other aircraft positions to properly receive, interpret, and display that information.  Legacy Avare does it very well (see the screenshot attached to my note above).  As do any number of other EFB apps.  AvareX still seems to be a work in progress in this regard, though.

[barry speronello]

Rich, the hardware I have works just fine as-is when the EFB software functions properly.  As the screenshot I posted shows, legacy Avare displays traffic just fine.  No additional hardware (or software) needed.

The AvareX team just needs to get a few kinks ironed out of AvareX and I'm confident that it, too, will properly display traffic received from an XGPS-170  ADS-B in receiver.

[Apps4av Support]

There are 2 GDL 90 message that provide more precise data about a traffic. I had it disabled for X because it is redundant. Simulation of recorded data show that it has some traffic that was not sent in the main iplinkessage. Were enabled in legacy app. Try and let me know.

Is the change in the GDL 90 messages present in AvareX build 0.77, or should I wait for a later build?  I've already installed the December 23rd (0.77) build which is the current one on the Play Store.

Also, re. GDL 90 messages (about which I know little).  The "About this app" info on the Play Store for AvareX mentions it when saying:  "Avarex supports ADS-B in data from any Wi-Fi GDL-90 device (Stratux....etc.) and will display traffic, weather, and other ADS-B received data."  Is it relevant to the problem that the XGPS-170 does not use Wi-Fi, but uses Bluetooth, instead?  Or should that sentence read "...any Wi-Fi or Bluetooth GDL-90 device...?"  In other words, could the fact that my device uses Bluetooth and not Wi-Fi to communicate with my tablet and phone be the cause of my issues?
