Need Help With My Project

i need you help…
i’m Thai
I’m sorry, I’m not good at English
I have a problem with my code, as in the example

    #define BLYNK_PRINT Serial
    #define BLYNK_DEBUG        // Optional, this enables more detailed prints
    #include <WiFi.h>
    #include <WiFiClient.h>
    #include <BlynkSimpleEsp32.h>
    #include <SimpleTimer.h>
    #include <SimpleDHT.h>

    char auth[] = "Ul3cq98pci8XCXbMoVrwQzVdHYPWN9bA";
    char ssid[] = "Zodiannm";
    char pass[] = "anm6024418050";
    char server[] = "blynk-cloud.com";
    int port = 80;

    int DHTSENSOR = 15;             //GPIO15 (ADC2_CH3)

    SimpleDHT22 dht22(15);
    BlynkTimer timer;

    void setup() {
       Serial.begin(115200);
   //   Blynk.begin(auth, ssid, pass,"blynk-cloud.com", 80); 

     WiFi.begin(ssid, pass); //เชื่อมต่อ WiFi      
     Blynk.config(auth, "blynk-cloud.com", 80); //-----------2
     Blynk.connect(); 
     timer.setInterval(5000L, sendSensor);    
    }

    void loop() {
      Blynk.run();
      timer.run();
    }

    void sendSensor() {
      byte temperature = 0;   
      byte humidity = 0;
      dht22.read(DHTSENSOR, &temperature, &humidity, NULL);
      while (temperature == 0) {
        dht22.read(DHTSENSOR, &temperature, &humidity, NULL);  
        Serial.println("DHT22 get failed");
        delay(1500);
      }
      Blynk.virtualWrite(V13, humidity);   
      Blynk.virtualWrite(V12, temperature);  
      Serial.print("Humidity: ");
      Serial.print(humidity);
      Serial.print("% | ");
      Serial.print("Temperature: ");
      Serial.print(temperature);
      Serial.println("C");
    }

form code

when i use this code

 WiFi.begin(ssid, pass); //เชื่อมต่อ WiFi      
 Blynk.config(auth, "blynk-cloud.com", 80); //-----------2
 Blynk.connect();

I will get results

Can you tell me why?
thank you for help :frowning:

Try starting with this sketch modified to your needs.

https://examples.blynk.cc/?board=ESP32&shield=ESP32%20WiFi&example=More%2FDHT11

I tried changing the wifi using my friend’s hotspot.
program is running

The conclusion is at the internet, right?

Yes, either you have a problem with your router, or your ISP is blocking the Blynk protocol.

5

Will the temp work right stored as bytes?

6

Then what methods can be prevented?
thank you

7

Reboot your router and see if that helps, or find a new ISP.

Pete.

From the example you provided

temperature is normal but humidity is abnormal
form picture When i convert the code

    #define BLYNK_PRINT Serial
    #include <WiFi.h>
    #include <WiFiClient.h>
    #include <BlynkSimpleEsp32.h>
    #include <SimpleTimer.h>


    #include "DHT.h"
    DHT dht;

    char auth[] = "Ul3cq98pci8XCXbMoVrwQzVdHYPWN9bA";
    char ssid[] = "iPhone";
    char pass[] = "bank1996";
    char server[] = "blynk-cloud.com";
    int port = 8080;

    BlynkTimer timer;

    void setup() {
      Serial.begin(115200);
      //เริ่มการเชื่อมต่อ Blynk Server
      Blynk.begin(auth, ssid, pass,"blynk-cloud.com", 8080);

     //WiFi.begin(ssid, pass); //เชื่อมต่อ WiFi
    // Blynk.config(auth,"blynk-cloud.com", 8080); //กำหนด Token key , ชื่อ Server และ port
     //Blynk.connect(); //เชื่อมต่อไปยัง Blynk
      dht.setup(15);
    //ตั้งเวลาส่งข้อมูลให้ Blynk Server ทุกๆ 1 วินาที
       timer.setInterval(5000L, sendSensor);    
    }

    void loop() {
      Blynk.run();
      timer.run();
    }
    byte a = 0;
    void sendSensor() {
      delay(dht.getMinimumSamplingPeriod());
      byte  humidity=0;
      humidity = dht.getHumidity(); // ดึงค่าความชื้น
      byte temperature = dht.getTemperature(); // ดึงค่าอุณหภูมิ
      a = map(humidity,0,255,0,100);
     
      //ส่งค่า humidity V13 ไปยัง blynk server
      Blynk.virtualWrite(V13, a);   
      //ส่งค่า temperature V12 ไปยัง blynk server
      Blynk.virtualWrite(V12, temperature);  
      Serial.print("Humidity: ");
      Serial.print(a);
      Serial.print("% | ");
      Serial.print("Temperature: ");
      Serial.print(temperature);
      Serial.println("C");
    }

If I don’t have this line

a = map(humidity,0,255,0,100);

The humidity is not a byte number but a float.
