> All wireless devices have small manufacturing imperfections in the hardware that are unique to each device. These fingerprints are an accidental byproduct of the manufacturing process. These imperfections in Bluetooth hardware result in unique distortions, which can be used as a fingerprint to track a specific device.

It's like sci fi movies where they track ships based on their engines. Turn off your transponder and they still know who you are, unless you really try to camouflage yourself.
Address randomization helps but it's not enough. The phone still transmits at a regular cadence so it's pretty easy to figure out which old address has changed into which new address and keep tracking the same device.
