kbluetooth-devicemanager do nothing (can't connect/disconnect BT headset)

[YaTaa]

Binary package hint: kdebluetooth

I have sennheiser mm200 bluetooth headphones.
I've successfully connected it via bluetooth-wizard (gnome-bluetooth package).
But can't do the same with kdebluetooth.

bash# kbluetooth-devicemanager
Object::connect: No such signal Solid::Control::BluetoothRemoteDevice::nodeCreated(const QString &)
Object::connect: No such signal Solid::Control::BluetoothRemoteDevice::nodeRemoved(const QString &)
