Ubuntu – Bluetooth not discovering any devices – Dell XPS 13 (16.04)

16.04bluetoothdell

I have looked at other solutions and threads for this problem but none of them have worked for me. I am using a Dell XPS 13 to connect my new Jaybird X3 earphones. So far, the laptop has been unable to detect neither my earphones nor my mobile device.

EDIT: All the devices are on discoverable mode. I've tried reinstalling Bluetooth using this answer https://askubuntu.com/a/776812/701563 and it did not work. I'm not sure why, but now BLueman Assistant says "No adaptors found".

I ran some commands in terminal and these are the results:

$ sudo service bluetooth status

I was able to finally fix this issue thanks to this answer: https://askubuntu.com/a/920803/701563

Step 1 - List your usb devices

lsusb

(Displayed this for Bluetooth for me)

Bus 002 Device 002: ID 0a5c:216f Broadcom Corp. BCM20702A0 Bluetooth

Step 2 - Go to https://github.com/winterheart/broadcom-bt-firmware/tree/master/brcm to download the converted driver that matches your ID from above. For me this was BCM20702A1-0a5c-216f.hcd (Click on the file to download it)

Step 3 - Copy the downloaded file to /lib/firmware/brcm

cd ~/Downloads
sudo cp BCM20702A1-0a5c-216f.hcd /lib/firmware/brcm

Step 4 - Reboot. Bluetooth should be working now.

If you get this error while connecting your Bluetooth Audio device:

Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol Not available

Solution: https://askubuntu.com/a/801669/701563

sudo apt-get install pulseaudio-module-bluetooth
pactl load-module module-bluetooth-discover

And then, delete the device from bluetooth devices and pair it again.

Hopefully this helps you connect your Bluetooth audio devices.
