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!)
They may just be other people’s various devices. Maybe IoT devices or devices not fully set up. If you’re living near a store/above a store, those might be Bluetooth beacons that track people through the store.
