Enabling USB Bluetooth Adapter Support

[Keith Conger]

Hi,

I had some questions about the USB Bluetooth adapter support in android-x86 that I'm hoping someone can help me with.  What kernel version and options/modules are needed.  Is there a trick to enabling it for my device?  What adapter chipsets are supported?  

Full disclosure I'm trying to get it functioning with my Beaglebone Black.  :)

Thanks in advance

Keith

Specify exactly what is your device so I can provide a patch to add your usb bluetooth adapter. Right now only RTL8723AU usb bluetooth is working, aside from generic devices.

[Keith Conger]

Its reported as a BCM92045B3 ROM

lsusb -v shows:

Bus 002 Device 009: ID 0a5c:2101 Broadcom Corp. Bluetooth Controller

Couldn't open device, some information will be missing

Device Descriptor:

  bLength                18

  bDescriptorType         1

  bcdUSB               2.00

  bDeviceClass          224 Wireless

  bDeviceSubClass         1 Radio Frequency

  bDeviceProtocol         1 Bluetooth

  bMaxPacketSize0        64

  idVendor           0x0a5c Broadcom Corp.

  idProduct          0x2101 Bluetooth Controller

Your device should be working...... post a logcat. it should have error messages about usb hci bluetooth.

[Keith Conger]

I have attached a logcat from bootup.

For some background, here is what I did to bring in android-x86's bluedroid.  Maybe I missed something?

I replaced libusb, bluedroid and added hardware/broadcom from android-x86 KitKat to my BBBandroid Beaglebone Black KitKat repo

I copied vnd_generic_usb.txt to /etc/bluetooth/bt_vendor.conf

I added the following to my BoardConfig.mk

BOARD_HAVE_BLUETOOTH := true

And the following in "kernel/.config", the kernel is 3.8

CONFIG_BT=y

CONFIG_BT_RFCOMM=y

CONFIG_BT_RFCOMM_TTY=y

CONFIG_BT_BNEP=y

CONFIG_BT_BNEP_MC_FILTER=y

CONFIG_BT_BNEP_PROTO_FILTER=y

CONFIG_BT_HIDP=y

Thanks for your help.

What you mean 'BBBandroid Beaglebone Black KitKat repo' ? What are you doing exactly?

Also, there's a lot of errors in logcat.

Out of the box android-x86 is working with all usb bluetooth, you don't need to change anything at all.

Do a 'repo sync' and build a new iso.

[Keith Conger]

Sorry I should've been more clear.  Beaglebone Black is an ARM platform, and I'm trying to add in android-x86's bluedroid.

This is great.  I'll give it a try. 

Thanks for all the help.

I noticed in one of the patches the bluetooth kernel modules are being unloaded.  So my kernel should not have bluetooth built in correct?

[André Vitor]

Those are incompatible modules with bluedroid.

It's needed because they can conflict with bluedroid functions.
