I'm using my SE C702 as remote for amarok over bluetooth.
For that, I use the build in remote application.
After I start the remote function, my phone ask me to pair the devices, I enter a pin, enter the pin on kde dialog too, and the remote app starts.
So far as normal (had worked fine in the past...). But now the "enter pin"- dialog from kdebluetooth comes again (remote isnt working at that point) and I have to enter the pin (or another) again - after that my phone will ask for this pin (this second pairing haven't happend in the past).
After that all is fine - remote working as expected, until I don't use the remote for some time - seems the connection gets shut down after some time of idle (this was also this way in past, so no problem). I i touch any remote button on the mobile, it will reconnect to the pc again - which worked fine in the past, but now brings up the pairing dialog again!
