Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1527

Is there a way to make the defined custom values to be persistant?

` WiFiManagerParameter custom_User_ID("User_ID", "Used ID", "", 30);

WiFiManagerParameter custom_Bot_Token("Bot_Token", "BOT token", "", 46);

wm.addParameter(&custom_User_ID);

wm.addParameter(&custom_Bot_Token);
`

This is my example of the values I want to keep across reboots/resets, does the library allows for this, or I need to write/retrieve them by myself from say EEPROM?

Thanks

you need to save them to fs yourself

solved it by using the Effortless SPIFFS library (https://github.com/thebigpotatoe/Effortless-SPIFFS)

`
String usid = custom_User_ID.getValue();
String toke = custom_Bot_Token.getValue();

if (usid !=""){
fileSystem.saveToFile("/usid.txt", usid);
}
if (usid ==""){
fileSystem.openFromFile("/usid.txt", usid);
userid = usid.toInt(); //userid is global
}

if (toke !=""){
fileSystem.saveToFile("/toke.txt", toke);
}
if (toke ==""){
fileSystem.openFromFile("/toke.txt", toke);
toke.toCharArray(buf, 80); // char token[80] is global
}`

Consider using littlefs, spiffs has been deprecated
