Compared to Unity 7 back in Ubuntu 15.04, Bluetooth support seems much simpler in Ubuntu Gnome 15.10. In 15.04 I had to key in the default PIN to pair my headphones. That, after a clunky process of retrying multiple times. After that, it was hit or miss whether Ubuntu remembers the pairing once you reboot the system.

On Ubuntu Gnome 15.10, pairing my headphones is much simpler.
- Set headphones to pairing mode.
- Click on your device in Gnome’s Bluetooth Settings.
- When it says “Connected” you’re done.
