Hi Marcel,
    Here is the content of /etc/bluetooth/hcid.conf

# HCI daemon configuration file.

        #
        security auto;
 
        # Pairing mode

        #   multi - Allow pairing with already paired
devices
        #   once  - Pair once and deny successive

        pairing multi;
 
        # PIN helper

}
 
# Default settings for HCI devices

        # Default link mode

        # Authentication and Encryption (Security Mode

        #auth enable;
        #encrypt enable;
}
How can I modify the Security Mode?
Also, how can I change the PIN of my Linux PC? 
Thank you very much.
Michael
