7 years ago it should not really do that. hopefully not anyway, as it has to successfully join the network and return true, otherwise it sets up an access point.
I do see your point thought. I would recommend one of the following...
1) re-upload the SPIFFS data folder from the example. this will reset it.
2) call settings.factoryReset() from your sketch which you can do just once..
3) add your own handlers in the main sketch to then call factory reset...
I've done 3 for another project...
where gpio 0 does a bunch of different functions. it relies on the Bounce2 lib. This code does a whole bunch of stuff... a short press toggles the value of one pin, a longer press causes a reset, and an even longer one causes a factory reset. i use it on my SONOFFs devices, and it works perfectly.
I still think that this sort of functionality is best handled in the actual user sketch..
// Update the Bounce instance :
bool changed = debouncer.update();
if ( changed ) {
// Get the update value
int value = debouncer.read();
if ( value == LOW) {
buttonPressTimeStamp = millis();
} else {
if (millis() - buttonPressTimeStamp < 500) {
output(!pin_state);
}
if (millis() - buttonPressTimeStamp < 10000 && millis() - buttonPressTimeStamp > 2000) {
_Debugf("\nRESTARTING....\n");
output(false);
delay(2000);
digitalWrite(STATUS_LED_PIN, HIGH);
ESP.reset();
}
}
} else {
if (millis() - taskTimeout > 100) {
taskTimeout = millis();
if (debouncer.read() == LOW) {
// creates flashhing status LED to indicate you're about to factory reset.
if (millis() - buttonPressTimeStamp > 2000 && millis() - blinkTimeout > 500) {
digitalWrite(STATUS_LED_PIN, !digitalRead(STATUS_LED_PIN));
blinkTimeout = millis();
}
if (millis() - buttonPressTimeStamp > 10000) {
_Debugf("FACTORY RESET....\n");
output(false);
digitalWrite(STATUS_LED_PIN, HIGH);
settings.factoryReset();
SPIFFS.remove(MY_SETTINGS_FILE);
delay(5000); // put a bit of a delay so you let go of the
digitalWrite(STATUS_LED_PIN, HIGH);
ESP.reset();
}
} else {
digitalWrite(STATUS_LED_PIN, LOW);
}
}
}

Looks like I have managed to mess up my WLAN settings with the result that I seem to be unable to get back in at all. Would be great if there was an easy way to reset all spiffs settings, e.g., by shorting a certain pin on the ESP.
