Preserving variables saved by EEPROM.writeDouble while upgrading #142

Closed TBKRK closed 1 month ago

TBKRK commented 8 months ago

Arduino board: esp32

Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.19

Hello, I still use version 1.1 of this library (I know... I should upgrade). Please let me know if upgrading code by this library (or later) will preserve the values of variables saved by EEPROM.writeDouble? I think sometimes after upgrading some of saved variables have different values.

Regards Tomasz

hi,

usually OTA updates don't affect the NVS partition, but you should backup your EEPROM values just in case
