samsung-golden uses a BCM4334 WiFi+BT combo chip. The BT part is connected via UART and supported by the hci_bcm driver in mainline. Add the necessary device tree changes to make it load correctly. It requires (seemingly) device-specific firmware that can be extracted from the stock Android system used on samsung-golden: - /system/bin/bcm4334.hcd -> /lib/firmware/brcm/BCM4334B0.hcd On my device, scanning for other Bluetooth devices works just fine, but for some reason it keeps disconnecting immediately when attempting to connect to an other device.
