Why are none of my changes persisting when I reset with the sample sketches?

In order to ensure that the Bluefruit LE modules are in a known state for the Adafruit demo sketches, most of them

perform a factory reset at the start of the sketch.

This is useful to ensure that the sketch functions properly, but has the side effect of erasing any custom user data in

NVM and setting everything back to factory defaults every time your board comes out of reset and the sketch runs.

To disable factory reset, open the demo sketch and find the FACTORYRESET_ENABLE flag and set this to '0', which

will prevent the factory reset from happening at startup.

If you don't see the 'FACTORYRESET_ENABLE' flag in your .ino sketch file, you probably have an older version of the

sketches and may need to update to the latest version via the Arduino library manager.
