sudo rfkill list; lsb_release -a; uname -a; dmesg | grep -i blue

Thanks

OK, use the web to see what the BCM.hcd file error is about

Seems the file needs to go into /lib/firmware/brcm

Will give you an idea on how to use a windows driver file to find the firmware hex file and convert it to the hcd file needed by Linux

Many thanks Jeremy, I feel that I'll solve the problem!

Let me summarize the steps I followed.

First, I downloaded Broadcom drivers for Windows 8 from the following link (http://drivers.softpedia.com/get/BLUETOOTH/Broadcom/ASUS-X99-DELUXE-Broadcom-Bluetooth-Driver-6515800-12009860.shtml#download). Then I opened the file by Archive Manager and found the bcbtums.inf located at Win64 directory. Then I searched the file for VID_0A5C&PID_216c. These numbers are from my lsusb output. Then I sow the file BCM43142A0_001.001.011.0197.0231.hex.

At this point I should extract the file, but I do not know how to do it. Can you help me please?

You may need to extract everything and then find the BCM43142A0_001.001.011.0197.0231.hex file and copy it into the hex2hcd folder. If you haven't used git or compiled anything you will need to install a few things

sudo apt-get install git build-essential

Then you can install hex2hcd

I did everything as recommended in the guide (https://askubuntu.com/a/632348/300665) and everything you suggested to me, but bluetooth still doesn't work. I can see both the files (BCM43142A0_001.001.011.0197.0231.hex and BCM43142A0-0a5c-216c.hcd) on the Home directory, but I'm not sure that the .hcd file went into the right directory (that is /lib/firmware/brcm).
Do you suggest a way to verify this?
Thanks to you, I feel I'm very near to the solution of my problem!!!

Try this command, it is one line, then reboot

sudo cp /lib/firmware/brcm/BCM43142A0-0a5c-216c.hcd /lib/firmware/brcm/BCM.hcd

Great Jeremy you solved my problem. I'm very happy!! I am infinitely grateful to you.
