Ubuntu 13.10 and Bluetooth on Broadcom BCM43142 WIFI+BT combo adapter


So, wireless and bluetooth on my spankin new Y510p are provided by a single Mini PCI-e Broadcom BCM43142 adapter. The wifi part worked out of the box, most of the time, but the bluetooth did not. There are evidence that this particular chipset is supported on certain Ubuntu certified Dell laptop models, but only up to Ubuntu 12.10. The attached .deb on that post can be installed on 13.10, but bluetooth is still not working. Bummer

Usually, to know what kind of bluetooth adapter do you have, or whether your box has a bluetooth adapter, all you have to do is:

lsusb | grep -i bluetooth

But surprisingly:

ikhsan@M5-X:~/$ lsusb | grep -i bluetooth
ikhsan@M5-X:~/$

No bluetooth adapter was identified. But I know the laptop has one, since it was actually detected by hciconfig

ikhsan@M5-X:~/bt/hex2hcd$ hciconfig 
hci0:    Type: BR/EDR  Bus: USB
    BD Address: 1C:3E:84:E5:BA:68  ACL MTU: 1021:8  SCO MTU: 64:1

    RX bytes:36699 acl:2135 sco:0 events:273 errors:0
    TX bytes:30967 acl:13 sco:0 commands:213 errors:0

So, unfiltered result of lsusb gave me this:

ikhsan@M5-X:~/bt/hex2hcd$ lsusb

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

There’s one entry that has no description. Googling  the device id confirms that this is indeed the bluetooth adapter that I’m looking for

dmesg gave me:

[   16.645428] Bluetooth: Core ver 2.16
[   16.645445] Bluetooth: HCI device and connection manager initialized
[   16.645453] Bluetooth: HCI socket layer initialized
[   16.645455] Bluetooth: L2CAP socket layer initialized
[   16.645461] Bluetooth: SCO socket layer initialized
[   18.861363] Bluetooth: hci0 command 0x1003 tx timeout
[   18.923343] Bluetooth: can't load firmware, may not work correctly

[   22.373782] Bluetooth: RFCOMM socket layer initialized
[   22.373784] Bluetooth: RFCOMM ver 1.11

So it’s a firmware issue. After further reading, this particular board requires additional firmware to be pushed during initialization, it supposed to be fixed , but here I am, with an a nonworking bcm43142 bluetooth on my Y510p. These are the steps that I did to get it to work:

  • Obtain .hex file for the bluetooth adapter. The easiest way is to do this is to to your windows partition, and copy the file from C:\windows\system32\drivers. The file should be named BCM43xxxx.hex. If there’s more than one file, consult your Windows device manager which file you should get. Or, if you have the same device id as mine, get it here,  this file is included on version 12.0.0.7820 of the bluetooth driver for Windows 8.1 X64. Put the file somewhere in your home folder, let say /home/ikhsan/bt

    BCMxxxxxx
    BCMxxxxxx
  • The .hex file need to be converted to a .hcd file. Replace 105b_e065 with your device id. Get the tool, convert, and place the hcd file to the firmware directory by performing
    $ cd /home/ikhsan/bt
    $ git clone git://github.com/jessesung/hex2hcd.git
    $ cd hex2hcd
    $ make
    $./hex2hcd ../BCM43142A0_001.001.011.0161.0172.hex fw-105b_e065.hcd
    $ sudo cp fw* /lib/firmware
  • Reload btusb module by performing
    $ sudo modprobe -r btusb
    $ sudo modprobe btusb

    If that doesn’t work, reboot the machine

You should now have a working bluetooth adapter. Dmesg after reboot and attaching my Razer Orochi  now gave me this:

ikhsan@M5-X:~$ dmesg | grep -i bluetooth

My Razer Orochi works normally, even the pairing survived a reboot. Strangely my Apple Magic mouse can be paired but still not working.

Update 8/3/2014:
So I decided to replace the Broadcom adapter with an Intel 6235AN adapter. It’s has 2.4GHz and 5GHz radio and  Bluetooth 4.0

        So bluetooth on your notebook is actually running.

        please do:

        dmesg | grep -i bluetooth

        and then, might as well try this. Put one of your bluetooth device in pairing mode (phone, headset, etc), and try to scan by doing:

        hcitool scan

        see if your bluetooth device is detected and listed. Output should be similar to this:

        ikhsan@fragfest:~$ hcitool scan
        Scanning ...
        	74:DE:2B:C7:0D:6F	Jabra CLIPPER
        

        If it is, try to install an alternative bluetooth manager such as blueman

      3. Eduardo Villaseñor says:

        Then I tried to do that you told me but I think that it doesn’t work at all because it is the output.
        eduardo@eduardo-SVF15215CLB:~$ hcitool scan
        Scanning …
        and I don’t get anything more.

  8. Eduardo Villaseñor says:

    I really thank your help

    1. ikhsan says:

      I’ve actually experience this before. Try to boot with liveCD, do lsusb, and see if it’s detected. One of my install also failed to list the device, and I had to reinstall it from scratch. If it’s still not detected, try to pair something from windows first, reboot, then repeat

  9. Eduardo Villaseñor says:

    I have been trying the whole day but it’s still not working I’m starting to get frustated.

    mentioned in next link http://askubuntu.com/questions/490346/bluetooth-not-working-in-ubuntu-14-04-lts, and is working for me, I rebooted and it still works, I thank you very much, now my bluetooth works. I have a Asus F201e with Ubuntu Studio 14.04

  14. Frank says:

    Thanks, works fine for me with lenovo edge e135

  15. massimo says:

    Hi all, lenovo b5400 and kubuntu: my bluetooth doesn’t work. I tried a hciconfig but give no answer and hciconfig dev says “Can’t get device info: No such device”. Any hint?

    1. ikhsan says:

      Google search tells me that the B5400 is equipped with either Intel 7260 or BCM20702.

      Can you tell me what kind of wireless adapter included in your notebook?
      also do:

      lsusb
      dmesg | grep -i Bluetooth

      and paste the output here

      the device id is the same as mine, so the module should be similar. Also I did not find error message that indicates your notebook failed to load the firmware. Can you show me the output of:

      you can try

    Device with id 04ca:2009 in lsusieb should be my dvd drive (according to google), but last time i entered “lsusb -v -d 04ca:2009” it showed the product: “BCM43142A0”, which usually is the bluetooth card. After applying your and another guide, i can’t find it anymore.

    I would really appreciate any help.

      Hi,

      Please test the bluetooth on windows, and retest it again on Ubuntu. Sadly I’ve encountered a case like this before. I used to run 2 install of ubuntu, one managed to detect the bluetooth adapter, and the other one does not. The only solution that I found back then was to reinstall ubuntu from scratch. If you are set on using ubuntu, you should research whether your BIOS has component whitelist and consider to replace the wifi/bluetooth adapter with a working one

    Hello,
    thank you for your solution to this BCM43142 issue, great article. My case was exactly the same as yours. Bluetooth is working well now.

    My laptop is Lenovo B590,

    “failed to open file” … what am i doing wrong?

    1. Johnny says:

      nvm,,, got it …. posted it into same dir as hex2hcd

      1. i had the same error “failed to open file” and i don’t understand what’s wrong?

  27. i have the same error “failed to open file” but i don’t understand what’s wrong?

    1. ikhsan says:

      you need to put the hex file into the same folder as where you clone the git and compile hex2hcd executable. In my case it was /home/ikhsan/bt/

      1. i copied the file into hex2hcd folder and the ” ./hex2hcd BCM43142A0_001.001.011.0161.0176 BCM43142A0-0a5c-21d7.hcd ” gave me the same error!

      2. i forgot .hex lol thanks, works fine now

    Hi Ikshan , I could get my bluetooth working with this procedure with 14.04 , i have lenovo B490 , now i have been trying the same using ubuntu 16.04 but bluetooth doesn’t work , is there something extra one needs to do … thanks for your help in advance

    1. ikhsan says:

      Unfortunately, I haven’t got the chance to try the card on 16.04

  29. Now I’m bummed that I blew away Windows without saving anything. I think the only way to get Bluetooth working now is to A: get a new wi-fi+BT card, or B: wait for Broadcom to (eventually, maybe) release the driver

    At least I know what the problem is. Thanks!

    1. ikhsan says:

      I think you can extract the file from the Windows driver, without having it installed first. I just took that route because it was the easiest way in my situation
