Adding --compat didn't work

[bitnom]

On Ubuntu 16.04 I modified /lib/systemd/system/bluetooth.service to show ExecStart=/usr/lib/bluetooth/bluetoothd --compat and then restarted bluetooth but still same error

Traceback (most recent call last):
  File "bluetooth_server.py", line 25, in <module>
    profiles         = [ SERIAL_PORT_PROFILE ]
  File "/usr/lib/python2.7/dist-packages/bluetooth/bluez.py", line 176, in advertise_service
    raise BluetoothError (str (e))

and service bluetooth status shows:

 bluetoothd[27411]: Not enough free handles to register service
 bluetoothd[27411]: Not enough free handles to register service
 bluetoothd[27411]: Current Time Service could not be registered
bluetoothd[27411]: gatt-time-server: Input/output error (5)

My other bluetooth devices are working.

Hmmm bluetoothd[27411]: Not enough free handles to register service that is a bit concerning. Were you able to find a resolution?

I have never run into this particular issue myself sadly

I added --compat and it did work for me (5.2.11-1-MANJARO). My output of systemctl status bluetooth shows:

I would suggest looking into fixing that Not enough free handles to register service error. I've found https://bbs.archlinux.org/viewtopic.php?id=195886 saying your BT may be RF-killed, but you indicated other devices did work, so I don't think that's the case. However, someone also suggested to rm ~/.config/pulse and that seemed to fix it for several people, so maybe you could try that too?
