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!)
Our Aldi now has electronic price tags for each product in the centre aisles. I wonder if they’re Bluetooth.
It varies. Some of them use Bluetooth Low Energy, some of them use other wireless techniques for lower power and greater range.
I have an idea, there are some restaurants around, maybe its these restaurant pagers.
They’re usually e-ink displays that get their power from NFC, so they’re probably not Bluetooth
