    ok, the phone doesn’t register every ble device it sees, just tracking ones…
    and then there’s an issue of registering the trackers, and some encryption involved.

    it still doesn’t work and some neato undetectable trackers have already been made, thanks to apple’s implementation.

      Third party apps like AirGuard will track all BLE devices and beacons around you, recording the detection location on a map. I just checked mine and it’s full of random iPhones, “Find My” tags, AirPods, and just 1 Tile

      It also has a separate risk analysis section for tracking tags whose identifiers may be randomized for privacy

        air guard is really good… but with the fake ones that randomize the mac address every beacon, it just registers a weirdly high number of devices… you have to look at it manually to catch it…
