RudolfAtRTC:
Thank you - but sorry, it doesn't help for me. In the readme.md is a question with a very exact answer:Q: The content of the FlashStorage is erased each time a new sketch is uploaded?
A: Yes, every time you upload a new sketch, the previous content of the FlashStorage is erased.During program optimisation there are some new uploads...
When I have stored some value pairs, they should stay permanently - even like an EEPROM.
The ESP8266 people have a solution, it looks like a special file, available also after reset/powerup and upload a new sketch.
the source of the Q&A?
