    APPLICATION SETTINGS

    FACTORYRESET_ENABLE     Perform a factory reset when running this sketch
    
                            Enabling this will put your Bluefruit LE module
                            in a 'known good' state and clear any config
                            data set in previous sketches or projects, so
                            running this at least once is a good idea.
   
                            When deploying your project, however, you will
                            want to disable factory reset by setting this
                            value to 0.  If you are making changes to your
                            Bluefruit LE device via AT commands, and those
                            changes aren't persisting across resets, this
                            is the reason why.  Factory reset will erase
                            the non-volatile memory where config data is
                            stored, setting it back to factory default
                            values.
       
                            Some sketches that require you to bond to a
                            central device (HID mouse, keyboard, etc.)
                            won't work at all with this feature enabled
                            since the factory reset will clear all of the
                            bonding data stored on the chip, meaning the
                            central device won't be able to reconnect.
