the problem is the same. Error 0x05 means "Authentication failure" and
this means that the link key is wrong. Since we don't have an easy way
to delete a single paired device from our list, you need to remove the
file /etc/bluetooth/link_key and restart the hcid. After that, your
keyboard should re-pair again.
