My bluetooth does not detect any devices - phones, other laptops, bluetooth speaker, keyboards, etc.

It just keeps searching and searching.

Here's a screenshot

I am very new to Linux, so I would really appreciate some help on this. Please tell me what additional information you guys need so that you can help me.

Output of: lspci -knn | grep Net -A2; lsusb

  • You can try by installing 'blueman' – Arijit Chatterjee Dec 22 '16 at 18:33
  • Please [edit] your question and add output of lspci -knn | grep Net -A2; lsusb terminal command. – Pilot6 Dec 22 '16 at 18:37
  • @Pilot6, I added the output to my question. – Kriss Atanasov Dec 22 '16 at 18:48
  • Your BT device is 04ca:2012 Lite-On Technology Corp. – Pilot6 Dec 22 '16 at 19:04
  • @Pilot6, I downloaded Broadcom Windows 8 driver from the first link that is provided but I could not find bcbtums-win8x86-brcm.inf file. Instead I only found: bcbtumsLD-win7x64.inf and bcbtums-win8x64-brcm.inf

    However I opened bcbtums-win8x64-brcm.inf and found the RAMUSB21D7 section and the name of the firmware file is: BCM43142A0_001.001.011.0197.0229.hex

    However I do not know how to do this: 4. Now extract that firmware from the same cab file.

    Would you please help?

  • Why do you search for 21d7 device if yours is 2012? You can extract a file by dragging it out by a mouse. – Pilot6 Dec 22 '16 at 20:41
  • @Pilot6, when I entered ~/hex2hcd/hex2hcd ~/BCM43142A0_001.001.011.0197.0229.hex~/BCM43142A0-0a5c-2012.hcd the following message comes in the terminal: Usage: /home/kriss/hex2hcd/hex2hcd

    Am I doing it right? I feel that something is wrong .. :(

  • There should be a space between the input and output file paths. And for Ubuntu 16.04 the output file name should be BCM.hcd. – Pilot6 Dec 23 '16 at 09:06
  • @Pilot6, first, I cannot find this file bcbtums-win8x86-brcm.inf. I downloaded the file from here: http://drivers.softpedia.com/get/BLUETOOTH/Broadcom/ASUS-X99-DELUXE-Broadcom-Bluetooth-Driver-6515800-12009860.shtml Second, when I try to find RAMUSB2012 I find nothing. I could only find the numbers of my BT device 04ca but that's it.

    Obviously that other explanation does not work for my case or I am doing it all wrong.

    I would appreciate some more help.

    Thanks in advance!

  • Name of the inf file can differ. If the 04ca:2012 firmware is not there, then you need to find another Windows driver for this adapter. – Pilot6 Dec 24 '16 at 08:44
