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!)
That’s not correct. They run on coin cells and use their own RF protocol. Most use something like zigbee. Others even use light to transfer data.
