Strange ...
Did you choose proper Flash size corresponding for your module in the IDE menu ?

HI yes, tried changing that in the IDE (https://github.com/esp8266/Arduino/issues/1486) and nothing helps.

I suspect this can be caused by Mac OSX as i had difficulties from the start to set this all up..

- Sat Jan 23, 2016 12:27 pm #39505 I don't see the relation between Mac OS X and EEPROM.
If your sketch is uploaded and running.
BTW, in your above, why is there a yield() function call ?

It was just a test to see if it helps - that i found somewhere in other sketch. However it's not there anymore, still i can save until rebooted.

Code: Select allvoid CSense::LoadConfig(tConfig& rtConfig)
{
  EEPROM.begin(512);
  delay(250);
  //
  rtConfig.m_strWiFiSSID = "";
  rtConfig.m_strWiFiPassword = "";
  rtConfig.m_strDescription = ""; 
 
for(int i = 0; i < 512; i++)
{
  char a =  char(EEPROM.read(i));

  Serial.print("EEPROM ADDRESS: "+String(i)+" VALUE: ");
  Serial.println(a);
 
}
Serial.print("\n");
 
  // Laod SSID First
  for (int i = 0; i < m_iMaxSSIDLength; i++)
  {
      rtConfig.m_strWiFiSSID += char(EEPROM.read(i));

  }

   // Load PASS
   for (int i = 0; i < m_iMaxPasswordLength; i++)
   {
      rtConfig.m_strWiFiPassword += char(EEPROM.read(m_iMaxSSIDLength+i));
   } 

   // Load Description
   for (int i = 0; i < m_iMaxDescriptionLength; i++)
   {
      rtConfig.m_strDescription += char(EEPROM.read(m_iMaxSSIDLength+m_iMaxPasswordLength+i));
   }     

  EEPROM.end();
  delay(250);
}



void CSense::SaveConfig(const tConfig& rtConfig)
{ 
  EEPROM.begin(512);
  delay(250);
 
  // Clear EEPROM
  for(int a = 0; a < 512;a++)
  {
    EEPROM.write(a, 0);
  }

  // Save SSID
  for (int i = 0; i < m_iMaxSSIDLength; i++)
  {
    if(i < rtConfig.m_strWiFiSSID.length())
      EEPROM.write(i, rtConfig.m_strWiFiSSID[i]);
  }

  // Save Password
  for (int i = 0; i < m_iMaxPasswordLength; i++)
  {
    if(i < rtConfig.m_strWiFiPassword.length())
      EEPROM.write(i + m_iMaxSSIDLength, rtConfig.m_strWiFiPassword[i]);   
  }

  // Save Description
  for (int i = 0; i < m_iMaxDescriptionLength; i++)
  {
    if(i < rtConfig.m_strDescription.length())
      EEPROM.write(i + m_iMaxSSIDLength + m_iMaxPasswordLength, rtConfig.m_strDescription[i]);   
  } 
 
  if(EEPROM.commit() == true)
  {
    Serial.println("EEPROM.COMMIT == TRUE");
  }
  else
    Serial.println("EEPROM.COMMIT == FALSE");

   

  delay(250);
}

On calling Save i get EEPROM.COMMIT == FALSE, meaning .commit() returns false;
