Now SmartConfig works!

I added:

sta_conf->bssid_set = 0;

to the .cpp file and recompiled. It made no difference. If I reset the ESP32 is searches forever until I use the phone app. Is there any else I need to do to effect the change?

Here's my connect function:

void setupWiFi () {
/* Set ESP32 to WiFi Station mode /
WiFi.mode(WIFI_AP_STA);
/ start SmartConfig */
WiFi.beginSmartConfig();

/* Wait for SmartConfig packet from mobile */
Serial.println("Waiting for SmartConfig.");
while (!WiFi.smartConfigDone()) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("SmartConfig done.");

/* Wait for WiFi to connect to AP */
Serial.println("Waiting for WiFi");
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("WiFi Connected.");
Serial.print("IP Address: ");
Serial.println(WiFi.localIP());
}

Here's verbose debug:

Hi bill-orange, you used just a SmartConfig sample code.
line WiFi.beginSmartConfig(); is always disconnect from old AP and start SmartConfig process.
If you not want to start SmartConfig after reset you have to rebuild the logic.

“Have to rebuild the logic”. Could you expand on that a bit. Also, not to be picky by shouldn’t this run on an Esp32 the same way it runs on an Esp8266 for code portability.

@bill-orange that is what I do

1. try to connect via stored SSID and password
2. if this fails (after timeout) start SmartConfig
   Example function that I call from within setup():

/**
 * Connect with SmartConfig
 * First try auto connect, if it fails
 * start SmartConfig
 *
 * @param confTimeout
 *        Time to wait to receive smart configuration
 *        if 0 it will wait forever
 * @param connTimeout
 *        Time to wait for connection to WiFi after
 *        configuration was received
 * @return <code>boolean</code>
 *        True if configuration and connection successfull
 *        False if timeout
 */
bool connSmartConfig(uint32_t confTimeout, uint32_t connTimeout) {
  WiFi.mode(WIFI_STA);
  WiFi.begin();
  uint32_t startTime = millis();
  while (WiFi.waitForConnectResult() != WL_CONNECTED) {
    if (millis()-startTime > connTimeout) { // check if waiting time exceeded
      // Timeout, start SmartConfig now
      startTime = millis();
      //Init WiFi as Station, start SmartConfig
      WiFi.disconnect();
      WiFi.mode(WIFI_AP_STA);
      WiFi.beginSmartConfig();
      //Wait for SmartConfig packet from mobile
      while (!WiFi.smartConfigDone()) {
        if (confTimeout != 0) {
          if (millis()-startTime > confTimeout) { // check if waiting time exceeded
            return false;
          }
        }
      }
      //Wait for WiFi to connect to AP
      startTime = millis();
      while (WiFi.status() != WL_CONNECTED) {
        if (connTimeout != 0) {
          if (millis()-startTime > connTimeout) { // check if waiting time exceeded
            return false;
          }
        }
      }
      return true;
    }
  }
  return true;
}

that is rather strange to make any difference

beegee-tokyo , Thank you for the code. It worked for me when I set the timeouts correctly. If I connect to a WiFi network and then move to another WiFi network will the first one fail and allow SmartConnect to look for the new one?

Shouldn't ESP32 and ESP8266 code work the same for something like this?

void setupWiFi () {
/* Set ESP32 to WiFi Station mode /
WiFi.mode(WIFI_AP_STA);
/ start SmartConfig */

if (WiFi.reconnect()) {
Serial.println( "reconnected from stored credentials");
WiFi.printDiag(Serial); Serial.println(WiFi.localIP());
Serial.println("Connected to wifi");
return;
}

WiFi.beginSmartConfig();

/* Wait for SmartConfig packet from mobile */
Serial.println("Waiting for SmartConfig.");
while (!WiFi.smartConfigDone()) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("SmartConfig done.");

/* Wait for WiFi to connect to AP */
Serial.println("Waiting for WiFi");
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("WiFi Connected.");
Serial.print("IP Address: ");
Serial.println(WiFi.localIP());

}

@bill-orange you are right, in my code is a mistake, should be WiFi.reconnect() instead of WiFi.begin(). But it worked for me before. Thanks for pointing out my mistake.
