Erase Configuration, setShowStaticFields and dynamic/ static Ip setting

kutty1999 commented 1 year ago

WiFimanager Branch/Release: 2.0.16-rc.2

Esp8266/Esp32: Esp8266

Hardware: ESP-12e

Core Version: 3.1.2

Description

I have no idea from get dns from the field tab in webpage and store in json in code i declared default dns as 8.8.8.8 then I need same as above for secondary dns.

I have faced three problems. The first one, on demand, I tried to erase the older configuration but it didn't work. The second one is static,dns, and custom parameter fields disappear after the initial configuration I declared the true value in the function. it will reappear after erase the configuration from the webpage. The third one is not switching between dynamic and static IP iam trying to switch the IP mode but it does not make it.

Description

I have no idea from get dns from the field tab in webpage and store in json in code i declared default dns as 8.8.8.8 then I need same as above for secondary dns.

I have faced three problems. The first one, on demand, I tried to erase the older configuration but it didn't work. The second one is static,dns, and custom parameter fields disappear after the initial configuration I declared the true value in the function. it will reappear after erase the configuration from the webpage. The third one is not switching between dynamic and static IP iam trying to switch the IP mode but it does not make it.

Thanks for reply @tablatronix I try to create a AutoConnect With FSParameters and CustomIP with ondemand to Starting Web Portal for configuration but i couldn't achieve my idea

I tried to erase the older configuration before starting web portal but it didn't work.

void loop() {
  static unsigned long buttonPressStartTime = 0;
  static bool buttonPressed = false;

  if (digitalRead(buttonPin) == HIGH) {
    if (!buttonPressed) {
      Serial.println("AP Button is Pressed");
      buttonPressed = true;
      buttonPressStartTime = millis();
    }
    if (millis() - buttonPressStartTime > LONG_PRESS_TIME) {
      WiFi.disconnect();
      WiFi.mode(WIFI_AP);
      WiFi.softAP("AP Mode");
      WiFiManager wifiManager;
      wifiManager.resetSettings();      //reset settings  
      wifiManager.startConfigPortal("AP Mode");
    }
      }
   else {
    buttonPressed = false;
  }

static,dns, and custom parameter fields disappear after the first configuration. I declared the true boolean value in the function. it will reappear after erase the configuration using erase config button in the webpage.

  wifiManager.setShowStaticFields(true);  // show Static IP  user Field 
  wifiManager.setShowDnsFields(true); // show DNS  user Field

Not switching between dynamic and static IP iam trying to switch the IP mode but it does not make it. I conform the dynamic not setting by the I unfill the static, and dns Fields it goes to custom ip configuration It take ip,gateway, subnet mask from the json file of older configuration, once set the static after unable to switch dynamic.

if (json["ip"]) {
            Serial.println("setting custom ip from config");
            strcpy(static_ip, json["ip"]);
            strcpy(static_gw, json["gateway"]);
            strcpy(static_sn, json["subnet"]);
            Serial.println(static_ip);
          } else {
            Serial.println("no custom ip in config");
          }
        } else {
          Serial.println("failed to load json config");

Someone else did this, I think they added a checkbox.

Are you adding them to wm? wifiManager.setSTAStaticIPConfig(_ip, _gw, _sn);

did you check the examples?
