DBus communication with the bluez core does not work on otoro. We can bring up bluetooth firmware on the otoro device, and can successfully scan for devices via low level commands thru hcitool, but actual gecko communication does not work. This is most likely due to the mix of dbus/bluez library and kernel versions on the phone at the moment.
confirmed working by echou as of kernelupdate5
And also as of kernelupdate6. Closing.
