Man it would be great to have an Android implementation. I like my MacBook running osx but I don't like iPhone hardware

Or lack of real software ownership e.g. no root allowed!)

99% of Apple consumers think root is something that grows out of the bottom of a tree.

Still waiting on an AirDrop client for non-Apple products. It works really well and is pretty convenient. Maybe this paper will help.

Zapya is one of the apps that almost everyone in SE Asia seems to have on their phones for transferring files back and forth in the absence of wifi networks. From what I could tell it is the primary way that music and photos are shared in Myanmar. It’s clunkier than airdrop, but x-platform.

I do wonder if there are patents on this, and if that has prevented other devices from adopting this kind of protocol? WiFi has always had AdHoc mode which enables two devices to directly communicate like they were on the same Ethernet link, and I've used it a few times for a similar use-case to yours. It seems AirDrop is just a layer on top of that which facilitates the configuration required, but otherwise it would…

Doesn't Ad hoc force you to disconnect from your current Access Point? I'm under the impression that this is not the case with Air Drop.

This is why AirDrop only works on some newer hardware: It requires Wi-Fi interfaces which can do Ad-Hoc and Infrastructure mode simultaneously.

Interestingly, they seem to based some of their research on the leaked source code for a Broadcom driver, which has now been taken down. So much for reproducible research, I guess?

Not in most cases, but it is somewhat chip (and driver) dependent).

Miracast is another example of this - In most cases you can remain connected to your main network connection via Wi-Fi but also use Wi-Fi direct to run a casting session.

Are you sure you don’t mean 99% of all phone or computer users do not know what root means?

so in the future - you can "war pop-up" random wifi's owners - by simply attempting to connect to the wifi and forcing a pop-up that says "Share wifi password with 'Save 15% of Geico's iPhone?"

No. It only works when you have each other within your Contacts list. https://www.macrumors.com/how-to/share-your-wifi-password-wi...

So are they tracking your contacts or can you spoof it from your phone? If one is not possible the other should be.

I still have openairdrop.org available to link to the first open source project to implement this protocol.

Wow. No love. Isn't lack of root like buying a house but the builder refusing to give you a master key or permission to change the locks?

On iPhone you have an iMessage acccount which is tied to the phone number. It can be done on the device, so it probably is.
