I remember - or maybe am mis-remembering - that years ago, SD cards used to exist with wifi access. I'm not sure whether you could read the card remotely? Or the card presented itself as a card, but actually streamed your data? But I remember that they existed? But the thing that struck me even more is that - again, I may be wrong - those cards actually ran Linux? They were super tiny computers? In a sense, I find it…

I deployed many of those things successfully a decade ago. Worked great!

This was one of the use cases of the SDIO [1] specification.

I have one of these $2000 SD cards in my Diamond DA40. It lets me connect my iPad to my aircraft so I can transfer updated databases, flight plans, and see real time avionics data. It's pretty cool. https://www.garmin.com/en-US/p/155337/

Damnnnnn that's cool but ouch. I know you're really buying the whole platform and capability and flight-worthy certification but $2K for what is basically a wifi dongle still makes my head spin.

Indeed, you are thinking of the eye-fi. https://en.wikipedia.org/wiki/Eye-Fi

Transcend made some too. I starred this blog in my feed reader, back in the day, w/ some exploration of their cards: https://jamesone111.wordpress.com/2014/03/19/exploring-the-t...

(Having my old feed reader archives is useful! >smile<)

You're correct on both points.

Some early wireless cards used SDIO to communicate with the host computer. These are long gone.

There were also some later SD cards which contained an embedded controller running Linux, which emulated an SD storage card and exposed its contents over wireless. The latter are what that article was about.

Aside: Is the DA40 as cool as it seems? >smileI've flown some 172s. When the DA40 came out I thought it seemed like a really, really neat airplane. I got some marketing lit and talked to people about it from Diamond at Sun 'n Fun (in 2004, I think). It's nothing I could have even remotely approach buying then (or now, unless I wanted to live in it, I guess) but I just wanted to soak up some of the aura of the thing.

What I’ve always wished is that I could take pictures with a nice DLSR or bridge camera and have a way to quickly load the RAWs into my phone for culling and processing. You could get the best of both worlds, better sensors and lenses, and simple developing within seconds. I know there are cameras with built-in WiFi that do this but camera manufacturers seem to let their software become outdated quickly.

The WiFi in cameras is definitively in the "do not use" category. It's usually some kind of flaky, broken, and/or slow.

I wish camera manufacturers just used Android on their devices, with possibly 5G for geotagging and time sync. It would immediately solve all the connectivity issues.

On Cirrus Perspective+ (Garmin G1000NXi) you can just Bluetooth the flight plans over from the iPad. It's really convenient when ATC reroutes me, to just enter it on the iPad and send it over instead of fiddling with knobs/keys.

Database updates are still using SD cards though, but just a normal one as far as I know.

As someone who has flown it just once with an instruction, my impression was that things were a little cramped for my taste. shrug

SDIO is still a fairly common interface that wifi and bluetooth adapters are connected with in embedded systems. Much lower idle power and protocol complexity than either USB or PCIe. You just don't find those wireless chipsets in an SD card form factor anymore. (and even if you did, SD card adapters don't generally support SDIO)
