I know what you are getting at! I have been trying to setup a WiFi range extender and it keeps giving me bad SSID and Passwords (something got messed up in the simulated "EEPROM" (used for arduino compatibility)).
The github link you posted no longer exists but I found this at least.
https://diyprojects.io/esp8266-how-read ... ce-needed/

which has the code:

#include <EEPROM.h>

void setup() {
EEPROM.begin(512);
// write a 0 to all 512 bytes of the EEPROM
for (int i = 0; i < 512; i++) {
EEPROM.write(i, 0);
}
EEPROM.end();
}

void loop() {
}

Hi there,

i would be very greatful if somebody could help me.
I did a testing with Spacehuhns Deauther Tool and set my Wifi to invisible. For some reasons i forgot my WIFI Passwort and want to clean the EPROM of my ESP8266-Board. I found this EPROM Cleaner on Schinfo's Github page: https://github.com/schinfo/EEPROM-Cleaner
but i sadly don't now what to do with that .info File. I only own that ESP8266-Board and an Windows PC. Do i need special Software or an Arduino for clearing the EPROM? I'm completely new to this. Many thanks in advance.
