I have problem with exception when changing Wifi.mode to station. First when ESP is turned on it setup itself as AP (setupWifi is first called in setup() ). Than i change settings on web configuration and save them on ESP, setupWifi is called again with accesspoint = false. Esp is than reset with Exception(28). Did a little of debug and it stops when WiFi.mode(STA) is called.

Code:

Code: Select all
void setupWifi(){
  //disconnect
  WiFi.disconnect();
  delay(1000);

  if(accesspoint){
      LOG.println("Nastavljam AP nacin");
      WiFi.softAPConfig(apIP,apIP,apMask);
      WiFi.softAP(ap_name,ap_pass);
      IPAddress myIP = WiFi.softAPIP();
      LOG.println("Ip naslov multisenzorja je ");
      LOG.print(myIP);
      LOG.println();
      delay(100);
    }else{
      WiFi.mode(WIFI_STA);
      if(config.dhcp){
        LOG.println("Povezujem z uporabo dhcp");
      }else{
        LOG.println("Povezujem z uporabo staticnega naslova");
        WiFi.config(config.ip,config.gateway,config.netmask);
      }
     
      //WiFi.begin(config.ssid.c_str(),config.pass.c_str());
      LOG.println("Status po station mode");
      LOG.println(WiFi.status());
     
      while ((WiFi.status() != WL_CONNECTED)) {
        delay(500);
        LOG.print(".");
        }

      if (WiFi.status() == WL_CONNECTED) {
        LOG.println("");
        LOG.print("Connected with IP: ");
        LOG.println(WiFi.localIP());
        }
    }
}

Code has Asyncserver running and when i trigger event from asyncserver it runs setupwifi again. Maybe setupWifi get's called multiple times? Because i tried create another script with async server and make it to change to station mode onclientdisconnect, and i get same problem.

Code: Select all
void onEvent(AsyncWebSocket * server, AsyncWebSocketClient * client, AwsEventType type, void * arg, uint8_t *data, size_t len){
  switch(type){
        case WS_EVT_CONNECT:
            Serial.print("Nov klient povezan ");
            Serial.println(client->id());
            break;
        case WS_EVT_DISCONNECT:
                accesspoint=false;
                setupWifi();
            break;
        case WS_EVT_ERROR:
            Serial.println("Napaka websocketa");
            break;
  }

}




Thanks for help!
