This requires the use of "undocumented", vendor-proprietary commands. In the source code of the Axis 'OpenBT' Bluetooth stack you can find how to do this for certain Ericsson and CSR-based devices. However, you need to perform a full reset of the device in order to make the change effective. Also, a device (at least the ones that I know) can only have one address at a time. In other words, the BD_ADDR cannot be changed on a per-packet basis. This is probably not want you want.
