AWDL is such an amazing technology, it's understandable that Apple wants to keep it only for their devices as it gives them a noticeable advantage for quick stuff sharing.

They didn't. Apple contributed the core logic to the Wi-Fi Alliance to build Wi-Fi Aware, which they now also support.

The EU required they use an open standard https://arstechnica.com/gadgets/2025/11/the-eu-made-apple-ad...

Interestingly, it still took the EU to force them to actually adopt it (and open it up for apps to use) in iOS 26.

Just use the existing magic wormhole protocol. It works and has been deployed for a long time.

No. It is using a central “well known server” and requires internet.

Test:

    * Does it work in an airplane?
    * Does it work in a submarine?
    * Does it work in the mountains, when a thunderstorm is approach and you need to share the GPX?

Basically my Garmin Edge and iPhone can do this. Magic-Wormhole fails in all test cases.

Implementation shall be able to negoiate a connection locally (e.g. Bluetooth) and upgrade to peer-to-peer WiFi if need (Garmin doesn’t need that part, GPX are usually smaller than 1024 KB).

My problem is that all these alternatives require the devices to be on the same local network. One beauty of Airdrop is that it creates and handles that local network automatically under the hood (as far as I understand). So you could be out on a hike with friends and Airdrop something. The workaround I've found after switching to an Android device has been to teather my connection to my friend's device, which ends u…

I am usually able to coerce a Localsend connection by using a WiFi hotspot on the target device.

Usually, but not always.

Seems weird there is no 802.n variant to do this very popular thing

That's precisely what Wi-Fi Aware (NaN) is and it is heavily based on AWDL. It's even built into recent versions of iOS and Android.

I've never heard of Wi-Fi Aware, thanks for sharing. Are there any devices/chips that support it today?

One Android phone supports it so far, and it's widely expected Apple will find some way to lock it out or at least delay more support.

Glass half empty kinda guy, huh? :-)

Not generally, I just don't have that specific phone that has implemented the workaround, and so this isn't a solution for me.

Apple has consistently done everything it can to self-sabotage their implementations of stuff to comply with EU anti-trust legislation like the stuff with digital marketplaces, so I'm not holding my breath on this.

I literally said that in my comment:
