As far as i know you can change the BD Address of a CSR BT chip by using CSR
vendor specific commands. At least, you can use an application they've made
to achieve this.

Hope it helps ...

you can change the BD_ADDR of almost every Bluetooth dongle, but as
Michael correctly pointed out, you must reset the dongle after it. So
changing the address on the fly is not possible.
