Unable to retrieve saved password from WifiManager while working with ESP32 Cam from Ai Thinker #1145

Open TheBluePhoenix10 opened 3 years ago

PLEASE TRY DEVELOPMENT BRANCH before submitting bugs on release or master, in case they were already fixed.

I can retrieve the password but cannot retrieve the SSID of my wifi

There is no such thing what are you using? Its not this library

String ssid = wifiManager.getSSID(); String pass = wifiManager.getPassword();

WM: [1] SSID: WM: [1] WM: [1] Reading Password WM: [1] Password: TheBluePhoenix@76 Stored SSID: WM: [1] Reading SSID WM: [1] SSID: *WM: [1]

I have no idea what this is...

TheBluePhoenix10 commented 3 years ago

There is, its just commented in the WiFiManager.cpp around line 379

here are the two blocks:

String WiFiManager::getSSID() {
  if (_ssid == "") {
    DEBUG_WM(F("Reading SSID"));
    _ssid = WiFi.SSID();
    DEBUG_WM(F("SSID: "));
    DEBUG_WM(_ssid);
  }
  return _ssid;
  }

  String WiFiManager::getPassword() {
  if (_pass == "") {
    DEBUG_WM(F("Reading Password"));
    _pass = WiFi.psk();
    DEBUG_WM("Password: " + _pass);
    //DEBUG_WM(_pass);
  }
  return _pass;
  }

ok well master branch does not support esp32 so I have no idea how you are using this code..

The dev branch / alpha version does support esp32.

Also the esp32 does not provide this info if the wifi has not been initialized

There are wrappers for this in dev with workarounds

    // helper to get saved password, if persistent get stored, else get current if connected    
    String        getWiFiPass(bool persistent = false);

    // helper to get saved ssid, if persistent get stored, else get current if connected
    String        getWiFiSSID(bool persistent = false);

// HELPERS

/**
 * getWiFiSSID
 * @since $dev
 * @param bool persistent
 * @return String
 */
String WiFiManager::getWiFiSSID(bool persistent){
  return WiFi_SSID(persistent);
}

/**
 * getWiFiPass
 * @since $dev
 * @param bool persistent
 * @return String
 */
String WiFiManager::getWiFiPass(bool persistent){
  return WiFi_psk(persistent);
} 
String WiFiManager::WiFi_SSID(bool persistent) const{

    #ifdef ESP8266
    struct station_config conf;
    if(persistent) wifi_station_get_config_default(&conf);
    else wifi_station_get_config(&conf);

    char tmp[33]; //ssid can be up to 32chars, => plus null term
    memcpy(tmp, conf.ssid, sizeof(conf.ssid));
    tmp[32] = 0; //nullterm in case of 32 char ssid
    return String(reinterpret_cast<char*>(tmp));

    #elif defined(ESP32)
    if(persistent){
      wifi_config_t conf;
      esp_wifi_get_config(WIFI_IF_STA, &conf);
      return String(reinterpret_cast<const char*>(conf.sta.ssid));
    }
    else {
      if(WiFiGenericClass::getMode() == WIFI_MODE_NULL){
          return String();
      }
      wifi_ap_record_t info;
      if(!esp_wifi_sta_get_ap_info(&info)) {
          return String(reinterpret_cast<char*>(info.ssid));
      }
      return String();
    }
    #endif
