My original question was this one: Bluetooth does not detect any devices [Ubuntu 16.04]

but it was marked as a duplicate however I could not find the solution even here: Bluetooth Broadcom 43142 isn't working on ubuntu

So, how can I fix this problem: "Bluetooth does not detect any devices. It just keeps searching and searching."

Here's a screenshot

It was recommended to me that I find another Windows driver for this adapter, which I do not know how to do.

[Edit] Output of: dmesg | grep -i blue; rfkill list

I would really appreciate some help here.

Thanks a lot in advance!

  • Are you sure you converted the correct firmware file? If you are sure that it is a kernel bug. The but nay be fixed in newer kernels, or may not. – Pilot6 Dec 25 '16 at 10:28
  • I did the following: Pasted this in terminal: ~/hex2hcd/hex2hcd ~/BCM43142A0_001.001.011.0311.0339.hex ~/BCM.hcd and then many many many lines appeared (I cannot copy them here, it's just too many lines) but it started with `15, :020000040021D9

    bump addr to 0x00210000`

    and then I got a BCM.hcd file in my home folder. The I typed this in the terminal: sudo cp ~/BCM.hcd /lib/firmware/brcm and the BCM file was copied in the brcm folder. Did I make a mistake somewhere along the way?

  • All looks correct. Then it is a bug with this adapter. There were some fixes in newer kernels. You can try kernel 4.8 from Ubuntu mainline ppa. – Pilot6 Dec 25 '16 at 10:51
  • @Pilot6, I turned the laptop off and on and the Bluetooth works!!! However, when I connect it to my Bluetooth loudspeaker I get no sound :( I checked the sound settings and it says that I am connected with Headset SBL 4.1 A1. (I've tested the loudspeaker with a cable and it works) any idea how I can fix that or am I going offtopic .. :) – Kriss Atanasov Dec 25 '16 at 11:13
  • The sound issue is another question. It can be solved, but I have no idea how. – Pilot6 Dec 25 '16 at 12:24
  • @Pilot6, Anyway, thank you very much for helping me solve this issue! :) – Kriss Atanasov Dec 25 '16 at 13:32

This is a new device. Download this driver

Open it with Archive Manager, then extract folder

drivers/DP_Bluetooth_16123/Broadcom/FORCED/8110x64/12.0.1.1011

There you will see bcbtums.inf file and firmware hex files.

The firmware for your 04ca:2012 adapter is BCM43142A0_001.001.011.0311.0339.hex.

Convert it to BCM.hcd using hex2hcd and copy it to /lib/firmware/brcm.

Generally speaking you can find Windows drivers for new BT adapters by internet search. In your case I found this driver by vid_04ca&pid_2012.

  • Okay, I did as you told me to and when I try to copy the BCM.hcd file to /lib/firmware/brcm I get the following message: Permission denied. I cannot either move or copy this file to the brcm folder. Obviously I have no permission to do that. How can I copy it to the brcm folder? – Kriss Atanasov Dec 25 '16 at 09:26
  • Read the http://askubuntu.com/questions/632336/bluetooth-broadcom-43142-isnt-working-on-ubuntu answer carefully. There is a command to copy the file with sudo. – Pilot6 Dec 25 '16 at 09:33
  • Okay, I successfully copied the BCM.hcd file and turned off and on the laptop. Now I have another problem, the Bluetooth cannot be turned on, see the screenshot It says "bluetooth is disabled". When I press the on/off button, the "on" is highlighted but when I close the window and open it again the Bluetooth is "off". And there is a short message below "Bluetooth is disabled"... How do I fix this now ..? – Kriss Atanasov Dec 25 '16 at 10:21
  • Please edit your question and add output of dmesg | grep -i blue; rfkill list command. – Pilot6 Dec 25 '16 at 10:23
