Hi Luiz!
First, thanks for your answer! For now I can't upgrade my ubuntu, but I
already tried to upgrade bluez launching classic shell commands such as
apt-get update, upgrade and dist-upgrade. But bluez remains at version
5.37. I have to tell you that I tried to uninstall bluez and than
reinstall it. It was a gamble and maybe it went wrong, but I'm not sure.
About the logs and the HCI traces I don't have knowledge to provide you
what you want on my own. Can you tell me what commands i have to put in
the terminal?
5.37 is quite old so there is a high risk there something new, like
LE/GATT connection, that happens to be unstable at that point. You can
use btmon to collect the the HCI traces:
sudo btmon -t
You can also check the daemon logs with:
sudo journalctl --unit=bluetooth.service
Thanks in advance for your help!

Hi all!
I am using Ubuntu 16.04 and there is no way to make the bluetooth work.
Every time I try to pair to my bluetooth headset bluez crashes. I really
don't know where to start solving this problem and I really hope that
someone on this list can help me.
Maybe it would help if you update your version of BlueZ, or better yet
update your ubuntu, if that still doesn't work then we may have a look
at some logs and HCI traces.
Thanks in advance for your help!
