The BCM4349B1, aka CYW/BCM89359, is a WiFi+BT chip and its Bluetooth portion can be controlled over serial. Two subversions are added for the chip, because ROM firmware reports 002.002.013 (at least for the chips I have here), while depending on patchram firmware revision, either 002.002.013 or 002.002.014 is reported.
