Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1461

Hardware

WiFimanager Branch/Release: 2.0.10-beta

Esp32:

Hardware: ESP32-Wroom 32D

Arduino IDE 1.8.12

Description

My problem is that the SSID and password are not saved after configuration. I upload the sample code in the EPS32 and configuration SSID And Password and Connect to Network. Every things is great. , but after power failure or restart, all information related to ID and password is lost and I have to re-configure. that is not good at all.

This problem only exists for ESP32 board.
"There is no problem when I run the same code on ESP8266.

Settings in IDE

Module: ESP32-Wroom 32D

Additional libraries: Version 2.0.10-Beta

Sketch

#BEGIN
/**
 * OnDemandConfigPortal.ino
 * example of running the configPortal AP manually, independantly from the captiveportal
 * trigger pin will start a configPortal AP for 120 seconds then turn it off.
 * 
 */
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager

// select which pin will trigger the configuration portal when set to LOW
#define TRIGGER_PIN 0

int timeout = 120; // seconds to run for

void setup() {
  WiFi.mode(WIFI_STA); // explicitly set mode, esp defaults to STA+AP  
  // put your setup code here, to run once:
  Serial.begin(115200);
  Serial.println("\n Starting");
  pinMode(TRIGGER_PIN, INPUT_PULLUP);
}

void loop() {
  // is configuration portal requested?
  if ( digitalRead(TRIGGER_PIN) == LOW) {
    WiFiManager wm;    
 
    // set configportal timeout
    wm.setConfigPortalTimeout(timeout);

    if (!wm.startConfigPortal("OnDemandAP")) {
      Serial.println("failed to connect and hit timeout");
      delay(3000);
      //reset and try again, or maybe put it to deep sleep
      ESP.restart();
      delay(5000);
    }

    //if you get here you have connected to the WiFi
    Serial.println("connected...yeey :)");

  }

  // put your main code here, to run repeatedly:
}
#END

Only time i have seen this is when flash is corrupt, a full nvs erase might fix it or try another board

I have used several types of ESP32 and still had the same problem.
At first, I used the ESP32 module and programmed it with ESP32 WROOM PGA Programmer.

Then I did the same thing on the development board like as DOIT ESP32 DEVKIT V1.
The same problem persisted in both Board.

What does your serial log look like?
what esp lib verison are you on, try to update it maybe ?

I run an Adafruit QT Py ESP32-C3 and had the same problem. Changing the Flash Mode (Arduino > Tools > Flash Mode) solved the problem for me. Drove me crazy!

Flash Mode: QIO : IMPORTANT -- THE C3 CHIP MUST USE QIO (not the default of DOUT).

oh wow interesting, maybe I can check that flash gets saved, I would expect esp lib to do this already, maybe I will raise an issue there also

Oh, lordy. It was driving me nuts. I finally found something that mentioned QIO for the -C3. If you need anyone to test against the Adafruit QT Py ESP32-C3, I'm your guy. I'm using this board for a number of things.

And, let me say: Thank You. This WiFi Portal is wonderful. I appreciate the effort you've put into it. I work on Assistive/Adaptive Technology, and this is being used to help folks control their hospital beds by voice. This is making a difference.

Its bad bootloader flash mode, have to clear pio cache and frameworks and reupload
