Unable to commit messages on EEPROM with this library

[jgarcia-atg]

Hello.

I am using IotWebConf library for configuring Wi-Fi and MQTT connection for a device based on ESP8266. Unfortunatelly, I have to write myself some parameters on EEPROM but when y commit the write, it fails. For example:

EEPROM.write(MemWifi,48); // (default: 5; maximum: 10) EEPROM.write(MemMQTT,48); /(default: 5; maximum: 10) EEPROM.write(MemADC,48); //(default: 5; maximum: 10) EEPROM.write(MemAHT,48); //(default: 5; maximum: 10) if (EEPROM.commit()) { Serial.println("EEPROM successfully committed"); } else { Serial.println("ERROR! EEPROM commit failed"); }

MemWiFi and so on are previously defined like:

define MemWifi 711

The problem is that when I call EEPROM.commit() it returns false, so I read on serial terminal "ERROR! EEPROM commit failed" I saw another Issue (https://github.com/prampec/IotWebConf/issues/60) and I tried his solution, but I'm still unable to commit the changes.

Any thoughs about this?

Thank you.

There was a fix, that fixed EEPROM was not closed after startup: https://github.com/prampec/IotWebConf/commit/b89ac9f61b2022cc0c794a74751c5019b4679eef Maybe that introduced new problem. E.g. it might happened, that EEPROM.end() was called, that disabled any further eeprom writes?

Hi @prampec .

Thanks for your reply. Do you mean that maybe I have to modify .cpp file?

[prampec]

Do you properly use EEPROM.begin() and EEPROM.end() ?

[jgarcia-atg]

First, I obtain the real size of the EEPROM memory with uint32_t realSize = ESP.getFlashChipRealSize() And then I initialize the EEPROM with: EEPROM.begin(realSize)

Also I tried calling EEPROM.end() at the beginning of the void setup but I am not even able to commit any writting
