Dear Sir/Madam,
Kindly change the SSID/ Password with your router SSID/Password in the code given below. Then load this code into ESP8266 using Arduino IDE software.
#include <ESP8266WiFi.h>const char* ssid = "RDL 4";
const char* password = "goalrdl54321";const char* host = "192.168.100.20";
const int httpPort = 8080;void setup() {
Serial.begin(9600);
delay(10);// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
}int value = 0;
void loop() {
ch:
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println(WiFi.status());
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
back:
delay(5000);Serial.print("connecting to ");
Serial.println(host);
// Use WiFiClient class to create TCP connections
WiFiClient client;
if (!client.connect(host, httpPort)) {
Serial.println("connection failed");if(WiFi.status()==0) // santhosh.sansoft@gmail.com
goto ch;goto back;
}
client.println("RDL 1");
delay(2000);
while(1)
{
while(client.available()){
String line = client.readStringUntil('\r');
Serial.print(line);
}
if(client.status()==0)
{goto back;
}delay(200);
}
