FlashMemory Address for EEPROM about arduino-esp32 HOT 4 OPEN

The EEPROM is saved as a blob in NVS. You can "address" an offset in that blob, but the actual blob address changes when you save the EEPROM. It's not a constant address in flash

You can "address" an offset in that blob, but the actual blob address changes when you save the EEPROM. It's not a constant address in flash

Is there a way through which we can read the offset and read the data only once and in further power cycles I will use NVS (key value pair) as I will copy to the NVS location.

Out of the 4 mentioned, the Machine ID is the most important one and I need to read.

I am not aware of such way. You can look into the EEPROM library source and convert that to pure IDF. It's just an abstraction .

Your time would likely be better spent updating whatever legacy code you have using EEPROM to use individual elements or a struct and store that in nvs rather than adding another inefficient compatibility layer.
