I made an app.

Nearby Glasses is here to warn you when smart glasses are nearby.

I hope it's useful for someone.

The app is now open source (AGPL-3.0), the app is free and rather simple

It's also downloadable outside the Play Store. iOS port is in the making. F-Droid is an option, will have to look into that

@yjeanrenaud Now we need an app to Jam them or make them stop working altogether.

That could be done by politly asking...and if that won't help, there's always a slap.😉

A device like the HackRF or Flipper Zero might be able to send something interesting over wifi or Bluetooth.
@dec23k @FandaSin @Pamela1960
flipper might even do the scanning trick beforehands, so there would be no need for that app
