RPi prioritizes Bluetooth the least of all protocols. So if you have other stuff running on the Pi, the Bluetooth can get the small end.
If possible, you can try deactivating built-in BT and connecting a dongle to make sure the BT isn’t faulty.
Regarding openHAB, could you specify what exactly the issue is? I’m not sure we are the right ressource, perhaps try posting on the openHAB forums?
