GDBus.Error:org.freedesktop.DBus.Error.AccessDenied #9

I installed the binding but nothing happens and I see the following error in the logs:

java java.lang.RuntimeException: Error getting object manager client:
GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 2 matched rules;

Cause: The "openhab" system user has insufficient permissions to access Bluez B-Bus interface.

Resolution:

  1. Edit Bluez DBus config to add a permission to access Bluez for the bluetooth group (/etc/dbus-1/system.d/bluetooth.conf): 
    <busconfig>
<policy user="root">
...
</policy>
<policy group="bluetooth">
<allow send_destination="org.bluez"/>
</policy>
...
</busconfig>
  2. Add openhab user to the bluetooth group: 
    sudo usermod -a -G bluetooth openhab
  3. Reload service definitions: 
    sudo systemctl daemon-reload
  4. Restart bluez: 
    sudo systemctl restart bluetooth
