Impossible to remove Bluetooth things, even if the binding is uninstalled
I am using an apt-get installed version of OpenHAB 2.4 on a raspberry pi v3 B with Stretch. I compiled the version 5.47 of bluez, following instructions in this thread.
I installed the binding and I succesfully found the internal radio (BlueZ 5.47) and a Xiaomi temperature sensor. By mistake I also added two generic bluetooth thing. Now I am unable to delete bluetooth things, even if the bluetooth bindings are uninstalled.
I tried installing and uninstalling the bluetooth bindings (the market on, of course).
I tried stopping openhab, clearing cache and I even tried removing the things from the Json text files.
This bluetooth things always reappear: where are they located?
In events.log I only find
2019-01-28 13:27:42.576 [hingStatusInfoChangedEvent] - 'bluetooth:ble:4C65A8D05ECE' changed from UNINITIALIZED to REMOVING
but the things always remains in place.
How can I clean my OpenHAB installation (without completely reinstalling from scratch)?
