Bluetooth not working on Ubuntu 16.04 LTS

Solution 1:

My ubuntu 16.04 couldn't find the Bluetooth devices, even though the devices's pairing switch was on.

Ubuntu 16.04 Bluetooth Speakers

In short, I tried following process.

1. sudo nano /etc/bluetooth/main.conf
2. Change #AutoEnable=false to AutoEnable=true (at the bottom of the file, by default)
3. systemctl restart bluetooth.service

Then, my Ubuntu machine was able to find the Bluetooth devices!

Solution 2:

After so many attempts to solve this issue the following commands did it for me.

rfkill block bluetooth

Then I do the following

rfkill unblock bluetooth

Solution 3:

I tried all the above but it didn't work for me, as the bt is not blocked but disabled and can't be turned on.

but i found this

sudo modprobe -r btusb
sudo modprobe btusb

and i got my disabled bluetooth come to life and pair with my headphones!

Solution 4:

My Bluetooth tended to "fall out", and I had to to do a reebot. But this solved it:

sudo service bluetooth restart

(easier than a reboot!)
