• ESP12-F saving variable

  in ESP8266 • 7 years

  

  Hi MaBe, thank you for your advise!
  above two links were tested on ESP12-F + "v1.95 4Mb" scatch. Unfortunately:

  Flash.getFree()
  Uncaught ReferenceError: "Flash" is not defined
  

  and

  var f = new (require("FlashEEPROM"))();
  Uncaught Error: Module "FlashEEPROM" not found
  

  In final I got "sunny night" and found one solution that was tested and passed:
  step 1) write in the left side of Web IDE two lines:

  function getName(){return "NR.3";}
  save();
  

  simple call getName() returns NR.3 even after power reset. Perfect begin!

  step 2) function was changed like below:

  function getName(){return "NR.12";}
  save();
  

  reboot by power and call getName() ruturns NR.12 now!

  Hope it will work for long time. Anyway, I will glad to get yours better ideas.

  Thank you, Mike

  Hi!

  Please help - *has somebody solved procedure to save and read variable values in ESP12-F or similar module?* I cannot find helpful JS-sample for Espruino Web IDE.

  My ESP12-F receives some data over WiFi and should save updated value of one variable. After power reset my ESP12-F should use updated value of that variable from the last session.

  Thank you for any idea!
