Bluetooth not working – Ubuntu 17.04

by

I’ve installed Zesty on my Zenbook UX510UX, but bluetooth is not working properly; I can connect my Honor phone, but I cannot send or receive anything, it says “Sorry, Ubuntu has experienced an internal error”.

Does anyone know what could be causing the problem, and how to fix it?

EDIT:

journalctl -p err -e --since today | grep -i bluetooth
apr 29 16:04:39 user bluetoothd[767]: Failed to obtain handles for "Service Changed" characteristic
apr 29 16:04:39 user bluetoothd[767]: Sap driver initialization failed.

Try running (without sudo)

systemctl --user start obex

And then initiate a file transfer.
