Good job so far. I believe you should focus on
Code:
Namespace lookup failure, AE_NOT_FOUND
Personally, I have no idea what it means, but an
internet search comes back with lots of results.
The Bluez error is not the root cause of your problem. It is generated by audio framework Pulseaudio, which fails to get in touch with the Bluetooth service. The Bluetooth service might not be enabled at all (software configuration error), or perhaps it crashed because of hardware or driver problems related to AE_NOT_FOUND.
