Not an expert in the field, but I have some knowledge. Bluetooth specifies different address types [1] where one of the types are Resolvable Random Private Address. This is used to avoid tracking. TLDR: The address is periodically randomized (typically every 15 min). Part of the address is a hash that lets you identify the device if you previously have bonded with the device (so you have its Identity Resolving Key) [1] https://novelbits.io/bluetooth-address-privacy-ble/ https://novelbits.io/bluetooth-address-privacy-ble/
