node mcu arduino เมื่อเชื่อมต่อwi-fi ใหม่ให้ทำการส่งข้อมูลไปยังServer อีกครั้ง ต้องทำยังไงคับ

#include <ESP8266WiFi.h>
#define LEDPIN D4
#include <ESP8266HTTPClient.h>


char ssid[] = "Network_Management";       
char password[] = "081xxxxxxx"; 
WiFiClient client;

void setup() {
   Serial.begin(115200); 
   pinMode(D4,OUTPUT);  

   
  WiFi.mode(WIFI_STA);
  Serial.print("name: ");
  Serial.println ("Car1");
  Serial.print("Connecting Wifi: ");
  Serial.println(ssid);
  Serial.print("password Wifi: ");
  Serial.println(password);
  while (WiFi.status() != WL_CONNECTED) {
  Serial.print(".");    
  delay(1000); 
  }
  
  Serial.print("\nIP address: ");
  IPAddress ip = WiFi.localIP();
  Serial.println(ip);
  

    digitalWrite(D4,HIGH);
    delay(1000);
    digitalWrite(D4,LOW);
    
HTTPClient http;
http.begin("http://192.168.xxx.xxx/project1/myproject/insert.php");
http.addHeader("Content-Type", "application/x-www-form-urlencoded");int httpCode = http.POST("null");
if(httpCode == HTTP_CODE_OK)
{
  
 Serial.println("Insert to database success !!!"); 
}
else
{
   Serial.println("Error in HTTP request"); 
}

http.end();
}
void loop() { 

    

}
