I hope that makes more sense! the Bluetooth SIG is working on something that is called Anonymity Mode and this should be present in Bluetooth 1.2, but it got removed from the final specification. So actually devices are trackable. And there is no default way of changing the BD_ADDR, but some manufacturers provides vendor specific HCI commands to change the Bluetooth address.
