I got ubuntu 16.04 and my Bluetooth is not working. I will give you the steps I have done so far.

1)$ lsusb | grep Blue

Bus 001 Device 003: ID 0a5c:21d7 Broadcom Corp. BCM43142 Bluetooth 4.0

2) Downloaded the .hcd file from https://github.com/winterheart/broadcom-bt-firmware/tree/master/brcm and pasted to /lib/firmware/brcm with name BCM.hcd

3) restarted, Still no luck.

4)$ dmesg | grep Blue

So what's next, read everything available online, I am completely stuck

My laptop : Dell Inspiron 15R 3521

*Wifi is working fine.

  • Totally shut the computer down, then boot – Jeremy31 Jul 11 at 20:49
