Will this device work with iGlide on IOS?

AirConnect compatible Wi-Fi connection service is active in the firmware's source code since October 9th.
Known to work good with SkyDemon, Air Nav Pro.
You could let us know if it works with iGlide too.

AirConnect compatible Wi-Fi connection service is a part of most recent firmware update.

I'm on the fence to add Flarm or something like this thread is all about to my glider in the upcoming off season. Any news or comment how this system is working presently would be appreciated.

You only need to ask these people ONE question: have you received (or even applied for) FCC approval?

If they can't answer this question affirmatively, don't walk, run from them.

Tom, not trying to start an argument, but I am wondering why you have made this conclusion. I am under the assumption that Flarm uses unlicensed spectrum to transmit.


Jonathan,

Well, then, you would be WRONG! FCC approval is mandatory for many very good reasons: unlicensed operators can be (perhaps inadvertently) interfering with other services, including vital aircraft and emergency services.


What "unlicensed operators"? There is no *operator license* required to operate on ISM frequencies.

This thread is talking about a self-built hobby project, I'm lost as to what you are talking about. Even the question you started with seems absurd -- "You only need to ask these people ONE question: have you received (or even applied for) FCC approval? " Who are "the people" who are supposed to ask FCC for approval? And for what exact approval?

You think FCC approval is needed for non-USA persons outside the USA to publish/share thoughts, ideas, designs, software source code? For USA persons to be able to access those items? What sort of police state do you think we live in?

I posted links to the 47 CFR 15. Even gave a simple summary. So again, there is a obvious carve out in the for home-built projects. 47 CFR 15.23. Did you read that? Covers intentional radiators. And if that home built project interfere with vital services the cure/penalty is... you stop using them.

If you think the TTgo devices being separately sold in the USA and used in these projects don't have any required FCC approval, then... knock yourself out and file a complaint with the FCC.

But even if those components are not properly certified that does not seem a legal issue for the purchaser. If a home-built project using those components causes interference, again it seems the regulatory cure is you stop using it.

Somebody marketing or selling a finished device, or construction kit with electronics components hardware... different concerns, that is not what is being discussed here.

(And to be clear, I have no interest in building anything described here. I have a workbench covered in ADS-B receiver projects and other toys as is. I am more than happy with PowerFLARM devices and have zero interest in taking risks hacking collision avoidance systems--I think Dave Nadler already raised valid concerns about that.)
