+void Disconnected(string reason, string message)
+````````````````````````````````````````````````
+
+	This signal is launched when a device is disconnected, with the reason
+	of the disconnection.
+
+	This could be used by client application, depending on internal policy,
+	to try to reconnect to the device in case of timeout or unknown
+	disconnection, or to try to connect to another device.
+
+	Possible reasons:
+
+	:org.bluez.Reason.Unknown:
+
+	:org.bluez.Reason.Timeout:
+
+		Connection timeout.
+
+		The link supervision timeout has expired for a connection or the
+		synchronization timeout has expired for a broadcast.
+
+	:org.bluez.Reason.Local:
+
+		Connection terminated by local host.
+
+		The local device terminated the connection, terminated
+		synchronization with a broadcaster, or terminated broadcasting
+		packets.
+
+	:org.bluez.Reason.Remote:
+
+		Connection terminated by remote host.
+
+		This disconnection can be due to:
+		- the user on the remote device either terminated the connection
+		or stopped broadcasting packets,
+		- the remote device terminated the connection because of low
+		resources,
+		- the remote device terminated the connection because the device
+		is about to power off.
+
+	:org.bluez.Reason.Authentication:
+
+		Connection terminated due to an authentication failure.
+
+	:org.bluez.Reason.Suspend:
+
+		Connection terminated by local host for suspend.
