I live in a big city in the center. When i activate “Show bluetooth devices without names” in the developer settings of my android 13 phone, there appear loads of this devices. I have no clue what they are. Does anyone know? Are that the bluetooth nanobots of the vaxxinated people? (/s to last question!)
Smart devices like switches, bulbs, outlets, etc; air tags and other brands of Bluetooth tracker; wireless speaker systems, headphones.
Many of these devices won’t broadcast a name at all, or will only broadcast a name while pairing.
