/*=========================================================================
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.
