I cross-compiled Bluez and d-bus library for the embedded linux and then I ran dbus-daemon and bluetoothd. But I can't connect devices on bluetoothctl. Scanning works on bluetoothctl and even connecting works on hcitool. Can't connect only on bluetoothctl and it makes this error: (failed to connect: org.bluez.error.failed)
I suspect there is a problem in d-bus daemon configuration but i'm not sure. The followings are my d-bus configuration.
System.conf
<!-- This configuration file controls the systemwide message bus.

file directly. -->
<!-- Note that there are any number of ways you can hose yourself
security-wise by screwing up this file; in particular, you
probably don't want to listen on any more addresses, add any more
auth mechanisms, run as a different user, etc. -->
