It is possible to change the BD_ADDR of certain BT devices. 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.
Cheers,
Michael
