> Sooo technically this is on the edge of legal/not legal, depending on your intent and what the judge had for lunch that day. ID'ing devices without consent is a grey area at best.

It's looking at the BLE advertising packets that they send out to everybody. The only thing stored is manufacturer ID, not a device ID (which you wouldn't be able to get anyways).

You might as well try to press charges against Apple or Google for putting readable names for nearby devices that aren't yours in the bluetooth pairing screen.

Filming/video and lookups of people filtered through a corporate data mining operation without their consent should also be illegal. I'll take my chances, thank you.

I recently had to interact with an idiot wearing meta glasses. There should be a mandatory consent requirement AND an "on air" red led.

> judge had for lunch

This would be a criminal matter, so a jury would have to decide if you're guilty. I feel like you'd have a hard time convincing 12 jurors that you're doing something wrong here.

I'd probably go for "the device explicitly allowed itself to be ID'd by intentionally broadcasting a signal intended for this purpose."

What region has laws that you're not allowed to look at a packet that was broadcast from a device? This sounds prima facie absurd, but I know a lot of strange laws exist out there.

Is this legal advice?
