Description

Problem description
Hi, I'm using your great library in a number of ESP32 devices and they lose wifi connection; sometimes after a few days, sometimes after just a few minutes. the code is multithread, the 'loop' section is empty. It seems that the reconnect-mechanism is not successful. The problem can be avoided by manually adding a reconnect routine in the 'loop' section:

void loop() {
  if ((WiFi.status() != WL_CONNECTED) ) {
  Serial.print(millis());
  Serial.println("Reconnecting to WiFi...");
  WiFi.disconnect();
  WiFi.reconnect();
}
delay(2000);
}

The setup is:

WiFiManager wm;
void setup() {
WiFi.mode(WIFI_STA); // explicitly set mode, esp defaults to STA+AP
  //WiFi.config(INADDR_NONE, INADDR_NONE, INADDR_NONE, INADDR_NONE); // required to set hostname properly
  //WiFi.setHostname("LF2battery");
  //WiFiManager wm;
    //wm.resetSettings();  //reset settings - wipe credentials for testing
    // Automatically connect using saved credentials,
    // if connection fails, it starts an access point with the specified name ( "AutoConnectAP"),
    // if empty will auto generate SSID, if password is blank it will be anonymous AP (wm.autoConnect())
    // then goes into a blocking loop awaiting configuration and will return success result
    bool res;
    // res = wm.autoConnect(); // auto generated AP name from chipid
    // res = wm.autoConnect("AutoConnectAP"); // anonymous ap
    
    //wm.setConfigPortalBlocking(false);
    wm.setHostname("myHost");
    wm.setCleanConnect(true);
    wm.setTimeout(3);
    wm.setConnectRetries(10);
    res = wm.autoConnect("myAP","password"); // password protected ap
    if(!res) {
        Serial.println("Failed to connect");
        // ESP.restart();
    } 
    else {
        //if you get here you have connected to the WiFi    
        Serial.println("connected...yeey :)");
        myIP=WiFi.localIP();
    }
}

Settings in IDE

Module: doitV1

Additional libraries: pubsubclient, ESPmDNS,

Is there a way to let the reconnect be handled correctly by the library? thank you
