this error is only at Ubuntu 14.10 at 14.04 is it working

[Huck-bernhard (huck-bernhard)]

addition:

if you call bluez-test-discovery few times stops discoverry of devices complete.
I can see a similar behavior at StartDiscovery with DBUS "org.bluez.Adapter" with QT5 and QDBusInterface
after connecting a device and disconnect because of distance device to long is Discovery also stopt.
after calling: "hciconfig reset" is Discovery working again.
this error is only at Ubuntu 14.10. with 14.04 is it working
