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.

|||
