I want to enable debug messages on bluez

I am actually trying to figure out where the DBG("") prints are going when I do a music stream using bluez to my headset. So basically I want to know where all the bluez debug messages are getting printed, be it any kind of bluetooth operation. ex: scan, inquiry , connect and so on .

Hopefully someone can help me with this . Thanks in advance .

To add to datafridge's answer above, I didn't have /usr/lib/systemd/system/bluetooth.service in Ubuntu 16.04 with BlueZ 5.41.

The file was at /etc/systemd/system/bluetooth.target.wants/bluetooth.service and the entry to be modified was 

ExecStart=/usr/lib/bluez5/bluetooth/bluetoothd –d

The logs can also be seen using

journalctl --unit=bluetooth -f

I have no Ubuntu here at the moment, but this is the way it works on Fedora and I'm sure it is very similar on Ubuntu, especially the systemd-part:

enable debugging by adding a -d after

ExecStart=/usr/libexec/bluetooth/bluetoothd

in /usr/lib/systemd/system/bluetooth.service

Save, then:

$ systemctl daemon-reload
$ systemctl restart bluetooth

Now you get your information in /var/log/syslog
