Stratus support?

[Steven Walter]

I understand that the Stratus ABS-B receiver is not currently supported by Avare.  I also found a forum post from several months ago, indicating that Stratus support might be forth-coming.  My question is, has the problem been a lack of time, access to hardware, or is it simply a Technically Hard Problem to reverse-engineer the Stratus protocols?  If it's the last possibility, I'd be interested in seeing whatever work had been attempted (wifi sniffs?) and giving a helping hand.

[Zubair Khan]

Hi Steven

First, there is a wonderful selection of ADSB receivers available for Android, why stratus?

Second, I believe that stratus specifically makes devices that only work with IOS, so there may be a HW compatibility issue.

Third, if HW compatibility is there, they may have an encrypted protocol with a key share with FF.

You have to ask yourself, if the effort is worth it when there are alternatives available? If you like to take this on as a hobby project then we are definitely interesting in supporting it.
Thanks

My interest in the Stratus specifically is a logistical one.  I would like to propose to my flying club that a community ADS-B receiver be purchased.  For most pilots, the ADS-B receiver to get is the Stratus, because it supports Foreflight and that seems to be what the majority of people are already using.  If that same ADS-B receiver also worked for me in Avare, that would be great.

Perhaps there is some other ADS-B receiver that Avare supports that also works well with iPad software?  Preferably Foreflight?  If that's the case, that would meet my needs nicely, I'm just not aware of such a thing.

[Richard Stigall]

I believe Stratus is the only one that works with ForeFlight.  I have a Stratus 2 and use Foreflight in addition to using Avare.  I would like for the Stratus to work with Avare as well.  I captured the data transmitted between the Stratus and ForeFlight, but did not get very far in reverse engineering it.  I don't believe there is anything magic (as I recall the Stratus would output data without Foreflight running) and it looked like it was possible to reverse engineer, but after seeing it wasn't easy, I gave up pretty quickly.

[Steven Walter]

If you wouldn't mind sending me the data you captured (or capturing some additional data), I would love to take a look at it.

[Richard Stigall]

I've sent the data to Steven.  If anyone else wants it - let me know.  The capture I did probably doesn't have any ADS-B data in it.  I was just trying to start with GPS.

[John Wiley]

> I believe Stratus is the only one that works with ForeFlight.

I'm trying to recall whether the reverse is also true. Are there any
apps other than FF that work with Stratus? If so, that would be a good
indication that it's possible with Avare. Hopefully the problem is just
that Stratus deliberately used a non-standard and undocumented data
stream in collusion with FF.

If you could simultaneously capture a stream from Stratus and a "normal"
receiver, it might make decoding the annoying Stratus stream much
easier. Maybe someone has access to both devices and could fly them to
capture both streams in this way?

[John Wiley]

> capture I did probably doesn't have any ADS-B data in it.

That may be the most useful and important part of the stream, since GPS
is so easy with a wide variety of devices including built-in with my
Nexus 7 and using Avare Bluetooth with a secondary device like the solid
GPS in my Samsung S4 phone. If the Stratus is dual band (1090 &
978MHz), that too would complicate the data stream but also add some
usefulness.

Frankly, to me the easier path would be to figure out a cheap dual band
receiver. Too bad that presently looks unlikely with a $10 RTL-SDR, but
I'm still hoping someone will do it on another inexpensive device. I
wonder if an NTSC USB HDTV receiver would work. Finding an alternative
ADS-B solution that's inexpensive enough might eliminate the need to
struggle with Stratus.

[Bill Helfand]

Stratus now works on Seattle Avionics' FlyQ EFB program.

It would really help if Avare could use the Stratus ADS-B receivers.

[Zubair Khan]

I wonder what we need to do to support stratus. I do not think their API is open or it connects to Android at all.

It uses Wi-Fi to connect.  Does it matter if that data stream is iOS or Android?  Does such a distinction exist?

Okay.  Sorry but that is just wrong.

Stratus works just as well with FlyQ EFB (from Seattle Avionics) as it does Foreflight.  I use my Stratus with both all the time.

Yes, FlyQ supposedly works with Stratus 2 but it is conditioned on not doing any firmware updates.

[Alan Krause]

The question was Why Stratus?  The answer is my partnership Cessna has a Stratus Transponder with ADS-B in.  I am already using Avare and I don't want to buy an iPad.

[John W SBA]

> Stratus Transponder with ADS-B in. I am already using Avare

I don't recall what's been suggested previously, but I gather you don't
want to buy a $150ish Stratux and hassle with putting it in/out of the
plane when using it. Also that for whatever reason, the Stratux In
built into the xponder doesn't use the same connection protocol as the
StratUS that the StratUX clones, so it doesn't work with Avare.

If the above is accurate, my suggestion is to get the "$10" SDR receiver
& app. Even tho I now use the StratUX I bought recently, I still keep
that unit in the plane as backup. If it were a rental/partner/club
plane all I'd need is a 3M pull-tab velcro on the flat part of the
interior trim beneath the side of the windscreen. That's what I have on
our 172, and it's all of a few seconds to install/remove the antenna
with corresponding velcro on the base (from which I've removed the
magnet). The app's quicker to set up/initialize than the Stratux, and
Mike Hammer's HIZ app has a few nice features beyond what what Avare I/O
provides. Here's some info on the cheapo I use that works just fine:
https://apps4av.com/2014/07/30/10-adsb-receiver-for-avare/

Mike's app with info on a presumably better and more expensive SDR can
be found here (and on the link to his website):
https://play.google.com/store/apps/details?id=bs.Avare.ADSB.Pro

If none of this helps, you'll probably want to look into other options
because my sense is there's nothing new coming to Avare in the near term
that would help you.

[Peter A. Gustafson]

Hi Alan,

I'm sorry to say NO support is forthcoming...

The last post I made on this was probably a year or more ago, so perhaps you saw something coming from somebody not active on the development team?

Stratus uses a non-standard, proprietary protocol.  The last time it was reverse engineered (not by us, another similar app), they changed it (most likely to break the reverse engineering job).  I talked to their team at OSH 2017 and was told it was a business decision and that for the forseeable future they were not going to play nice with other software providers.  So our team isn't going to waste our time... I had hoped they would see the value of being compatible and thus maybe selling more of their devices.  But I think they are in a contract with Foreflight that has a non-compete clause.  (Just speculative).

[midlifeflyer]

I can echo Peter's comment. AFAIK, there have been two EFB apps which "cracked" the Stratus code - FlyQ and iFly GPS. iFly lost the battle early; FlyQ lasted longer and still supports the units if the firmware is old enough.

But a question - you mentioned Stratus "transponder." If that's the case, you are talking about a Stratus panel mount, not the portable. Not the same thing. At that point, it's not about Stratus, but about the panel GPS in the cockpit. The Stratus transponder  (with ADS-B and depending on model) exchanges info with panel mount GPS - Garmin 430/530/GTN and Avidyne 440/540. Those, in turn, will exchange information with a portable/tablet using WiFi or Bluetooth. It's a feed from panel GPS to EFB, not from Stratus to EFB.

The Garmin connect product uses FlightStream, a Garmin add-on, which will connect to Garmin Pilot and ForeFlight. Not sure, but I think it's closed source. The Avidyne wireless product is more open and will connect with a wider variety of apps, including ForeFlight, FlyQ EFB, FltPlan Go, and a few others.  

I suspect that, for Avare, the better option will be looking into Avidyne connectivity than Garmin connectivity. My sense is that Garmin is keeping it tight, while Avidyne would like to connect to anything out there.

[ejess...@gmail.com]

Just to be clear, the Stratus ESB is ADS-B out only.  It has provisions to share power and antenna with a permanently mounted Stratus 2 behind the panel, which is identical to their portable version as far as sending out data.

[Peter A. Gustafson]

Yep, this product is the one which will go no support, at least not from
me.  :(

(Unfortunately, it is also the one in my own panel... I learned the
lesson the hard way.  My partners did the research and bought this for
our plane... they also fly only with apple devices and FF.  I figured I
could make it work... cuz it seemed like a good deal.  Tried for about
an hour, then learned the backstory and gave up.)

As a general guide, the team is usually willing to attempt to support
any device that uses a standard protocol or at least defines it clearly
(via some support mechanism).  It typically requires a user request and
access to the hardware.  Occasionally people/companies have donated or
loaned hardware to facilitate integration.  Its an all volunteer team so
nobody is generally out there "looking" for that next hardware revenue
stream. :)

Update: stratus 3 has an open ads-b option gdl 90. Using that setting on the stratus horizon app and avare i/o wifi shows traffic on avare.

[Brad Walker]

Eric,

Could you provide some more details..

Are you saying that Stratus 3 puts out GLD90 frames that contain ADS-B information?

I'm actively doing some work on the FIS-B side of things (at a protocol level and not Avare), so I'm interested in this.

Thanks.

Brad,

Stratus 3 outputs GDL90 protocol frames that avare i/o can readily aquire traffic information over the default wifi connection to stratus. I haven't tested the FIS-B yet since I'm currently testing it on the ground and not near any ground stations. When I go up for a flight test I'll let you know if weather information transfers too.

Brad,

The new Stratus 3 and 3i  can use the GDL-90 protocol and therefore will work with any other program that accepts GDL-90 info--per tech support at Stratus.  The catch is that the Stratus 3 and 3i by default do NOT put out GDL-90 info unless you turn on GDL-90 within the STratus 3i, (this does not apply to stratus2 or earlier which are only apple centric).  The rub is that you need to download Stratus Horizon Pro--an apple only product, to turn on GDL-90.   Stratus tech support told me now there is a free Android program called FltplanGo which has a feature that will turn on the GDL-90 output so AVARE can use it.  I just tried to use FltplanGo to turn on the GDL-90 and couldn't do it as I couldn't establish a connection with my Stratus 3i---My Samsung Tablet connected to the Stratus 3i, so trouble shooting that one.  The FltplanGo program is clunky--I would only use it to turn on GDL-90 and then go back to AVARE!

I tried using FltPlan GO to enable ‘open mode’ on the Stratus 3i and I was unsuccessful too.  The Tablet connects to the stratus but I cannot connect FltPlan Go.  Here is what FltPlan Go tech support says:            BTW I did have Location Services enabled for the App.

 

My apologies – I see that you are using an Android device.

 

Using the GDL-90 button should bypass the need to enable Open ADS-B in the horizon pro app.

 

Can you make sure you have Location Services for FltPlan Go enabled on your device?

I am installing the Stratus 3i as we speak due to my Stratux being very unreliable.  I plan to have the installer set the GDL-90 format before I take delivery.  However, I would like to be able to communicate with it on my own.  Has anyone had success with the FlightPlan Go app??  I hate to buy an iPad just to have the Stratus Horizon Pro app.

Open up FltPlanGo. On the pop-out menu, select "External". In the top left corner, there should be a "Devices" button. Select "Stratus 3". (Tap "Devices" again to hide that list.) I'm not near my Stratus 3i right now, and I don't recall if it switches automatically, but if not, you can select "GDL90 Mode" from that screen. Screenshots attached.

Barrett, That may work for the stratus 3 but does not work for the 3i.  It seems there is a difference.   I have tried it repeatedly after working with both FltPlan Go and Appareo support groups.  There doesn’t seem to be an Android app that will work to change modes for the 3i.  Once the mode is set to open it works fine.

Weird. I don't remember having that problem. I have an Apple device available to me, so I may have done it that way, but I thought I remembered being able to do it all from FltPlanGo. I've messed with several combinations of Apple, Android, 3, 3i, and various EFBs, so I could very well be mixing those up. Either way, I'll try to play with it later tonight. At the very least, I'm sure everyone knows somebody with an iPhone who would be willing to download the Stratus Horizon Pro app to make the switch. Appareo really should port that over to Android.

Barrett

[Bruce & Alice Brooks]

I agree completely with your last statement, but here is what Appareo said!!!

 

For those that do not use Apple devices, some app developers, as previously mentioned, have wrote in the ability to automatically be put in Open ADS-B mode. Again, it is up to the app developers. We choose to be Apple only. If you would like to pay for an app to be created, feel free to send an email to solu...@appareo.com and they can provide a quote to you. I don't even know if they will tell you it is possible as I'm sure a software engineer would need to be hired specifically to design on the Android platform. I suggest you reach out to the app developer for the one you utilize to put a request in, if they don't support this already, for the Open ADS-B mode.

It makes sense that Stratux members of the Avare community might be
willing to offer financial incentive. Since the main purpose for
Stratux owners seems to be turning on "open" capability, how about
leading an effort to build a small Android app for that single purpose?
If built open source it could probably be hosted on the Apps4Av
distribution channels and Forum.

Many other aviators have obviously chosen the Stratus products after
careful consideration of the options. It's clear to me that having
compatibility with such a popular product suite would be a boon to those
with Stratus hardware who seek other app alternatives.

I'm concerned that integrating Stratux into Avare would probably be a
significant and ongoing distraction for our Dev Team. Not only has
Stratus explicitly stated their initial intention for closed
architecture and app developers, they have deliberately disabled
competing apps with their firmware changes. So even adding
compatibility for one of their devices may not work with all versions of
that firmware, nor with other or future models and versions.

A bigger concern for me than distraction of our Dev Team is the risk
that adding integrated compatibility could introduce bugs, or detract
from the many things all the other Avare users enjoy.

Might you be willing to fund and build a small Android app for
activating Stratux compatibility?

[Eric Jessen]

Just to be clear, we are talking about the stratuS 3i.  I would think that the app to activate the GDL-90 format would be stand alone and not actually part of Avare.  With out knowing how much would be needed, I will say that yes, I am willing to donate to such an app.

[Bruce & Alice Brooks]

Yes, since Appareo has stated in no uncertain terms they are unwilling to support Android users and since they provided an open  interface using standard GDL-90 message formats it will be up to app developers if they wish to use it.  Any Foreflight users get a message to force the proprietary interface so when non-forflight users want to use the 3i you must have an IOS device to reset it to ‘open’ mode.  I put the 3i in my plane because it was advertised to support Android EFBs even though it cost more than other options.  I am disappointed and bought a stratux box for me to use while my partners use the 3i.   I would happily donate to a solution that makes switching without an Ipad easy.

 I agree that a separate app enabling stratus support might be a worthwhile endeavour, mainly to help those who already have or share a stratus, but I do not feel that having this inside the main avare app would be necessary or even desirable. It just does not make any sense to buy stratus unless you use foreflight and ipad, since you get exactly the same features for less than half the price on a multitude of different stratux boxes currently on the market. To put it bluntly: Stratus is a ripoff, taking advantage of the captive Foreflight market.

[Bruce & Alice Brooks]

Bernhard,

It would be great if Appareo provided a way for Android EFBs to access the Open Mode but they don’t.  I chose the Stratus for several reasons.  I was upgrading to ADSB out and the combo of the Stratus Xpdr and 3i had a reasonable cost and a 5 year warranty.  The 3i is convenient since it is permanently mounted in the plane and comes on with the avionics and does not require batteries or usb power cords. No flimsy antennas, suction cups or Velcro either.  I don’t need to carry it  and chargers in my flight bag.  The AHRS is configured and calibrated once and stays there.  A negative is that the 3i was advertised as working with multiple EFBs which was a bit misleading when I discovered the need for the mode switching which requires an IOS device and it will not support OPEN and ForeFlight at the same time.  Appareo says it is up to app developers if they don’t use IOS.

 

A separate app for android mode switching like the IOS app ‘Horizon Pro’ would work just fine and meet the needs of owners who have a need to switch the 3i back and forth between modes for different users.  Including it in Avare would be nice and save a step just like bringing external I/O into the app vs the external one.  Don’t forget the stratux (with and x) also has a separate app for some of its features too.

I'm happy to see that there might be some financial incentive for an
Android app to enable switching the 3i. My uninformed guess is that it
might not be too hard, especially if there's already some Android code
that does it. Without hacking another developer's code, maybe
monitoring the data stream between app and 3i could be enough. If not,
even knowing it's been done and there's some demand (and cash support)
could offer encouragement to an enterprising code expert.

> Including it in Avare would be nice and save a step...

Good point. Keep in mind though that the StratuX is quite popular (esp.
in the Android environment), the code involved is open source, and it's
already translated to html (web interface) making it even easier to
implement in Avare. So the fact it's not fully implemented in Avare is
an indication of the complexity, potential pitfalls, and reluctance of
our core Dev Team for doing it.

Two questions come to mind:
*Can FF users get full 3i features in GDL-90 format?
*What's the cheapest iOS/app combo to switch a 3i to GDL-90?

[Bruce & Alice Brooks]

John,
First to answer your 2 questiions.
FF users CANNOT use GDL-90 mode. As soon as FF is opened it prompts to switch to FF mode.
I don’t know how cheap a used I-thingy would be but my wife has an old Ipad that will not install and run the free 'Horizon Pro' app.

I don’t know what comm. protocol IOS uses to talk to the 3i so I don’t know how you would trace it. They claim it is a version of wifi that still allows users to use their wifi for other uses while using FF. Appareo does seem willing to provide some specifications to Android app developers. Tracing the GDL-90 messages once the 3i is in open mode should be easy as it works just fine with Avare over wifi.

Bummer, but not unexpected.

> I don’t know how cheap a used I-thingy would be

Could be helpful info for everyone else wanting 3i/Avare, if you have a
way of finding out.

> my wife has an old Ipad that will not install

I'm so glad to have no iStuff. :/

> free 'Horizon Pro' app.

If it's open source, maybe the developer would be willing to help an
Android coding volunteer? If not, maybe willing to write an Android
version with your financial incentive, encouragement, and possibly
Android code help? Of course, maybe not since it seems many (most) free
non-open source apps seem to earn their keep with ads and spyware.

sigh...

> Tracing the GDL-90 messages once the 3i is in open mode

My understanding is that's not needed. Just finding out how to switch
it. Probably a very short data string, though maybe encrypted or
something to annoy Android developers.

[Eric Jessen]

I installed the 3i because my Stratux kept abandoning me at very inopportune times.  It would go hours without talking to a UAT tower.  I like the way it uses the Stratus ESG antenna and GPS info.

[Dmitry Korotkov]

I do not know how they do it, but FltPlan Go for Android switches Stratus to OpenADSB mode. I just googled that somewhere. The steps are just to open FltPlan Go and add stratus as an external device. It'll switch OpenADSB on without any confirmations/warnings. After doing that I could keep using Avare.

With more than one pilot for the airplane it would be very handy to have Avare to turn on OpenADSB automatically.

[Jeff Hurst]

Yes Fltplan Go works now.  I think it is because a number of us contacted them about it previously only opening Stratus3 and not the newer 3i so they fixed it!

I to have heard FPgo can set open mode on the 3i however I have not had success when trying it twice recently.  I ended up buying a junk iPhone a few months ago for the sole purpose of setting open mode on the 3i.  My problem may be pilot error but the iphone  the ‘Horizon pro app’ always works.   I also have read the FF will support GDL90 data from non Stratus devices so I don’t know why it insists the 3i must be in FF mode not open mode.  I suspect that when/if we get an easy way to set the 3i to open people will also want AHRS to work on AVARE too.

> previously only opening Stratus3 and not the newer 3i so they fixed

My very limited understanding is that it would be trivial for someone
with solid understanding to "sniff" the connection from FPG to S and
figure out what it's sending, then duplicate that for Avare in a simple
stand-alone Apps4Av applet.

My impression of S is that they're walking a fine line placating the
widest possible customer base, without annoying FF & Garmin. If there's
any truth in that, my fear is that when enough people find easy ways to
use S in any and all apps they'll push an "update" to change the "open"
activation code. Hasn't that already happened in the past?

Were I stuck with an S (owned, co-owned, club, etc.) other solutions
would be more appealing. If owned, I'd sell, replace it with a StratuX
and enjoy the cash return along with all the advantages of a truly open
system. If otherwise stuck, I'd fly with my own solution (StratuX or
"$10 ADSB In"). If my club had an S I'd lobby for co-installation of a
StratuX since they'd presumably both work and thus provide redundancy.
My tiny (see attached) $10 unit is always in my flight bag, so I could
just use that.

Meanwhile, it would be great if someone hacks the S code and adds it as
an Avare option or applet. Even if S then changes the code, at least it
would annoy enough people that S would get more negative feedback about
advertising "open" when it's not.

[Jeffrey Ross]

I don't have a Stratus unit to tinker with, however if somebody here
does and can successfully put it in "open mode" using fltplan go, we
might be able to obtain a capture of the bluetooth commands sent. Maybe
with that somebody can write a simple app to enable open mode?

If I'm reading things right, in order to get the data needed in a
nutshell you will need to enable developer mode and then a feature
Bluetooth HCI snooping, then perform the steps to connect to the Stratus
and put it in open mode.  Once that is done simply retrieve the log file
created and it can be viewed using wireshark.

If there is anybody willing to try obtaining the data and needs
assistance reach out to me directly and I'll try to walk somebody
through the procedure.

Jeff

[Andrew Sarangan]

I tried fltplango and could not connect to the Stratus. I read somewhere that iflygps works so that's what I am going to try next.

Ooops, was just corrected the Stratus uses Wi-Fi not Bluetooth, I don't
know why I got Bluetooth in my head.

Trying to reformulate a plan.

I am new to this group and trying to get my transponder to send ads b info to Avare.  Here are specifics:  I just installed Appareo Stratus 3i in a Cessna 172.  All works fine with I Fly GPS.  I wanted to use Avare with same but cannot get it to connect with the Stratus for receiving traffic and weather.  I communicated with Appareo support and have attached their communication below.

I am open to any ideas or updates regarding same situation that others may have.  thanks, mike

NOTE FROM APPAREO:

Mike,

I know we've had a few questions about Avare in the past.  The challenge is there is no one really to reach out to as I believe it's managed by bloggers.  I believe we put a note on their forums to see if someone could reach out to see if they could get in contact with us, but I don't think anyone reached out.  The app developers have to tie in the lines to ensure the app can talk with the Stratus.  

Unfortunately, I don't believe we have any near future plans to release Stratus Horizon Pro to Android.  

What I've told people in the past is to look for used iDevices online as you can normally find some pretty cheap devices.  

Thanks

Appareo Support

Hello: I recently installed a Stratus 3i system in my Cessna 172i. The system works great. I also am using a Samsung 7 Tablet on my yoke with the Ifly GPS program. I also connects and works well with the wifi. I would like to use the open source Avare software program as back up but cannot seem to receive data from the Stratus unit for that program. I was going to download the Horizon Pro app but notice it is only for ios and not android? Is that correct? If so, when might an Android version become available? Many of my fellow pilots getting tired of being tied to apple products due to pricing. Thanks for your help with this. mike

[Barrett Thompson]

Scare works fine with the 3 and 3i. The stratus just has to be put into open Ads-b mode. All Avare would need is a simple feature to change this setting. FltPlanGo will do this, and I believe someone on the forum developed another separate app that would do it, too. But you can't change the setting using Avare. Annoying, but I don't mind having a backup app anyways. And once it's changed, the setting sticks (unless it's a shared thing where other people might be using it).

Scare -> Avare*.

My new phone still autocorrects...

[Bruce Brooks]

Michael,

I also have the Stratus 3I and it works fine but it must be set to “Open Mode”  To set it to Open Mode I use an app on the tablet called “UDP Sender” to send the command to the 3i .  once set it will stay in that mode even through power cycles until someone changes it back to FF mode which is Appareo’s default.  Attached is a screen shot from my Samsung tablet showing the settings required to set the 3i to open mode.  We are still hoping Avare will someday include the code to change the mode since the 3i is a popular unit.

 

See attached screen shot.

I don't think you will ever get it to work.  Some have had luck with the Stratus 3, but not the 3i.  You would think they would be the same, but they are not.   Stratus has absolutely no interest in anything non-apple, so don't hold your breath for any support on their end.  I ended up drinking the coolaid and bought a iPad mini 5 with FF.  I still have Avare on my old tablet as a back up, but I have no ADS-B in for it.

[michael lombardi]

Thanks for the feedback.  I may try some of this and I may all the Appareo support group and see if possible to build a relationship with somebody in tech side.  mike

If the Stratus 3i supports "Open Mode" like the Stratus 3 does then you are in luck, there is a program written by Andrew Sarangan (he's on this forum) called "ADS-B Monitor" this is a small program that you can run on an android device to put the Stratus in open mode.

If the Stratus 3i doesn't support open mode then you are out of luck.

Link in the playstore for ADS-B Monitor - https://play.google.com/store/apps/details?id=org.sarangan.adsb

Haha, the note from appareo is a funny one.  I'll buy a tasty bev at OSH for the first person to find the note they supposedly posted in our forum trying to find developer contact info.  :)

FWIW I handed my business card to the Stratus guys at OSH a few years ago, described our dev team, etc.  (This was pre- open mode, and in fact they actively broke a reverse engineered protocol to prevent use beyond idevices.)  I was told there was no market and little interest on their side.  Thankfully they at least came out with open mode... perhaps they see a bigger market there now than they did back then?

If any appareo people are come across this post in future, send me a note and you will soon have full access to the dev team.

Thanks for a hearty laugh, Mike. :D

I just logged in to check email, so haven't seen the helpful replies
you've probably already received. Just wanted to say how funny that
Appareo reply is, since so many Avare users have tried to get help from
them.

[michael lombardi]

Jeff:  I tried to use the app but could not get the 3i to respond.  I used the settings in your pix and was wondering if maybe i should have tried different settings.  Not really sure what port number is for my plane as an example.  Anyway I will continue to play around with it.  Thanks!   mike
