Im writing a connection library in C++ for a Bluetooth low energy device using the D-Bus interface. I'm able to connect and receive messages from the device, but after some time (usually a few minutes) the device disconnects and I find this in the syslog: aug 25 15:14:30 arch.laptop gnome-session[706]: ERROR:dbus.connection:Exception in handler for D-Bus signal: aug 25 15:14:30 arch.laptop gnome-session[706]: Traceback (most recent call last): aug 25 15:14:30 arch.laptop gnome-session[706]: File "/usr/lib/python3.4/site-packages/dbus/connection.py", line 230, in maybe_handle_message aug 25 15:14:30 arch.laptop gnome-session[706]: self._handler(*args, **kwargs) aug 25 15:14:30 arch.laptop gnome-session[706]: File "/usr/lib/python3.4/site-packages/blueman/bluez/PropertiesBlueZInterface.py", line 55, in wrapper aug 25 15:14:30 arch.laptop gnome-session[706]: handler(name, value, **kwargs) aug 25 15:14:30 arch.laptop gnome-session[706]: File "/usr/lib/python3.4/site-packages/blueman/plugins/applet/GameControllerWakelock.py", line 34, in on_device_property_change aug 25 15:14:30 arch.laptop gnome-session[706]: klass = Device(path).get_properties()["Class"] & 0x1fff aug 25 15:14:30 arch.laptop gnome-session[706]: KeyError: 'Class' Looking in the documentation for bluez, Class should be an optional property. Also, the location of the error indicates that the it identifies the device as a game controller (GameControllerWakelock.py), but it is not. Any idea what could be wrong? -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
