You can be tracked via your Bluetooth MAC address

Your Bluetooth MAC is like the earlier MAC address except it is for Bluetooth. Again, it can be used to track you as manufacturers and operating system makers keep logs of such information. It could be tied to a sale place/time/date or accounts and then could be used to track you with such information, the shop billing information, the CCTV, or the mobile antenna logs in correlation.

Operating systems have protections in place to randomize those addresses but are still subject to vulnerabilities102.

For this reason, and unless you really need those, you should just disable Bluetooth completely in the BIOS/UEFI settings if possible or in the Operating System otherwise.

On Windows 10, you will need to disable and enable the Bluetooth device in the device manager itself to force randomization of the address for next use and prevent tracking.

In general, this should not be too much of a concern compared to MAC Addresses. BT Addresses are randomized quite often.
