I have the same problem. Moreover if you set "export QDBUS_DEBUG=1" before using qdbus you see that whatever you write is interpreted as string. I solved using dbus-send I used
dbus-send --system --print-reply --type=method_call --dest=org.bluez /org/bluez/1384/hci1 org.bluez.Adapter.SetProperty string:Powered variant:boolean:true instead of qdbus --system org.bluez /org/bluez/1384/hci1 org.bluez.Adapter.SetProperty Powered true -- qdbus does not forward booleans in args correctly https://bugs.launchpad.net/bugs/458654 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to qt4-x11 in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
