We consider your Bluetooth device was not recognized by Ubuntu 16.04 for some reasons-

Device Model- Dell-Inspiron-3521

Bluetooth hardware- 0a5c:21d7 Broadcom Corp. BCM43142 Bluetooth 4.0  (to get the name of Bluetooth hardware run lsusb in terminal.)

Ubuntu version: 16.04 LTS (any series)

Tested on kernel version: 4.4.0-122-generic (to get the version of current kernel uname -r in terminal.)

Steps to make Ubuntu kernel version- 4.4.0-122-generic recognize your Bluetooth device:

  1. Download the drivers from here – Download Broadcom 0a5c:21d7 Bluetooth Drivers for Ubuntu.
  2. Go to the download folder where you downloaded drivers and in terminal issue the command below :sudo cp BCM43142A0-0a5c-21d7.hcd /lib/firmware/brcm/BCM.hcd
  3. After copying the drivers : sudo modprobe -r btusb
  4. At last sudo modprobe btusb
  5. Now Reboot the system and you will see the Bluetooth indicator in the system tray at top right corner.
  6. Now turn on the Bluetooth and in Bluetooth settings add a new device 🙂

You are done, enjoy.
