From this previous questions it seems like it is not a trivial exercise: Can Bluedroid be used in raspberry pi instead of BlueZ

If you need to avoid using D-Bus, then have you looked at the BlueZ Bluetooth Management API? https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/mgmt-api.txt

There are various options at compile to remove parts of BlueZ that are not required on a system: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/README
