Unfortunately, your Bluetooth device:
Is not supported by any version of stock Ubuntu, please refer to
Bug1129865 [Broadcom Combo BT/Wifi Card] 21D3 21D7 Bluetooth does not detect anything at all
(The reason is listed in comment #7)
And I will suggest you to subscribe to this bug:
Bug 1065400 Support for loading Broadcom bluetooth firmware
There might be a workaround in that thread, good luck!
Sources:
- https://askubuntu.com/a/534632/336592.
To have a complete solution I write all my steps from the beginning:
Find ID of your device:
My output for example:
from which 0a5c:21d7 should be remembered.
Get a hex file for your device:
- After searching for bluetooth drivers in Google I have chosen this download: http://drivers.softpedia.com/get/BLUETOOTH/Broadcom/Broadcom-43142-Bluetooth-40-Adapter-Driver-12007030-for-Windows-8.shtml#download
- I have extracted the last .hex file by chance. Fortunately it worked. STEPS: In nautilus right-click on the downloaded .cab file > chose Open with Archive Manager > select last .hex file in the archive list > right click >Extract..
- download and compile hex2hcd
- convert the .hex to .hcd
Copy the hcd file to /lib/firmware as lib/firmware/fw-0a5c_21d7.hcd.
In the filename use the ID which you have previously found out.
Managed services wordpress templates. Answers saying that I have to install Windows to get a firmware for Linux .. sound wrong, isn't it?
But the previous answers were gold. I have Bluetooth working after long time in my Dell with Ubuntu 12.04 386.Here my completions to the previous answers (especially sb):
The sb's cab is good and had the hex files for several chips on this family.
cabextract is a tool to extract a .cab archive. just:
sudo apt-get install cabextract
and extract it by:
Be aware that there is not a directory inside the cab, but just files, so you'll get a lot of hex files. It is good to mkdir a specific directory and extract the cab in there.
- How to get the right hex file.
So I have the id of the chip: 0a5c:21d7 and a bunch of the hex file. How can I get the right one for me?The trick is to investigate the .inf file that instructs windows what to install.Searching for 21D7 (note the capital D instead of 'd') I get this:
%Dell1704.DeviceDesc%=RAMUSB21D7, USBVID_0A5C&PID_21D7 ; BRCM Generic 43142A0 RAMUSB
Ubuntu 14.04 Iso Download
The USB/VID&PID is what I get on lsusb: capital(0a5c:21d7).The RAMUSB21D7 is what I need to search next in the inf file (it is the device's description).
And this is my result:
Ubuntu 14.04 Download
And the hex file I shall use is BCM43142A0_001.001.011.0122.0126.hex
The rest is the same as above. Get the tool trough git, build it, convert the hex file to hcd, discard/reload the btusb.
Note: Be aware the hcd file should start with fw-... and not fw_... I made this mistake. :)
I have solved the issue with the solution from this post:
In summary, I have done this steps:List your id:
My id is: 0a5c:21d7
Get the file .hex :In your windows partition (presuming that you dual boot with Windows), get the file BCMxxxx.hex in C:windowssystem32drivers.If there are two or more files .hex, view which one is in use with windows device manager.Copy this file in your home directory
Open terminal and type these commands:
Reload modules with these commands:
Restart your computer.
Open terminal and write:
if all right you can view the message:
This is all.
Good luckDiabolik2
WilfIn my case the bluetooth firmware did not load until I created the brcm directory in /lib/firmware/ and renamed the file to
BCM43142A0-0a5c-21d7.hcd
I'm using Debian 8 & Dell Inspiron 15
Cheers
Solution works (Ubuntu 14.04 kernel-4.2) In my case, HCD file needed to be named BCM.hcd.The exact file name you should name your hcd file will be stated in description of loading error, which can be viewed using command:
as Wilf stated above!
