yocto-2.0 (jethro) does not support bluez4 by default, it has been set
deprecated, but there is some functionality that does not work with bluez5
like bluetooth audio with alsa and some previous scripts like hdp.py are not
API compatible.
In order to compile a project with bluez4, just remove bluez5 from distro
features from your local.conf project.
DISTRO_FEATURES_remove = "bluez5"
