NVS involuntary resetting memory about arduino-esp32 HOT 16 CLOSED

One time more in the field.
But now without disconnect the device.
The device just stopped to work and after turn off and turn on the NVS was cleared.

Are you being sure to call preferences.end() after you modify things to ensure it is stored/committed to flash?

Couple of things:

• The code posted is only part of the overall sketch? There is not shown the .begin() nor the .end() statements.
• The code uses, for example, preferences.getUChar("configFabrica", 170); which in this form will return the default value you specify of 170 if there is an error when doing the getX(). If the Preferences namespace it not properly initialized or opened with a .begin() then this may appear like the NVS has issues.

All the getX() methods commit to NVS before returning so unless the device resets at that exact time they should be safe.

Hi.
Thank you about your comment.
Yes. The end are in a function in the final.

Hi.
Thanks about your comment.
Yes is in the setup.

The problem heppening not in the first time when turn of the devie.
The problem start after some hours the device on or when turn on and turn of several times.

Any chance you can try with newer version? 2.0.17 or 3.0.1? 2.0.2 is really old (and all 2.0.x will be EOL next month).

Dear me-no-dev, sorry close your comment. The chat is new for me. But update the IDE is not the solution. I think the problem is with the hardware.
