Hi got pice of modified code but still not working as supposed too
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
// WiFi information
const char WIFI_SSID[] = "SSID";
const char WIFI_PSK[] = "PASSWORD";
// Remote site information
const char http_site[] = "mywebpage.com";
const int http_port = 80;
// Pin definitions
const int LED_PIN = 5;
// Global variables
WiFiClient client;
void setup() {
// Set up serial console to read web page
Serial.begin(9600);
Serial.print("Thing GET Example");
// Set up LED for debugging
pinMode(LED_PIN, OUTPUT);
// Connect to WiFi
connectWiFi();
// Attempt to connect to website
if ( !getPage() ) {
Serial.println("GET request failed");
}
}
void loop() {
char d;
// If there are incoming bytes, print them
if ( client.available() ) {
int c = client.read();
Serial.print(c);Serial.println(" "); //// no needed for now
}
if (d = 48){
digitalWrite(LED_PIN, LOW);
}
else if (d = 49){
digitalWrite(LED_PIN, HIGH);
}
// If the server has disconnected, stop the client and WiFi
if ( !client.connected() ) {
Serial.println();
// Close socket and wait for disconnect from WiFi
client.stop();
if ( WiFi.status() != WL_DISCONNECTED ) {
WiFi.disconnect();
}
// Turn off LED
digitalWrite(LED_PIN, LOW);
// Do nothing
Serial.println("Finished Thing GET test");
// client.println(c);
while(true){
delay(1000);
}
}
}
// Attempt to connect to WiFi
void connectWiFi() {
byte led_status = 0;
// Set WiFi mode to station (client)
WiFi.mode(WIFI_STA);
// Initiate connection with SSID and PSK
WiFi.begin(WIFI_SSID, WIFI_PSK);
// Blink LED while we wait for WiFi connection
while ( WiFi.status() != WL_CONNECTED ) {
//digitalWrite(LED_PIN, HIGH);
//led_status ^= 0x01;
delay(100);
}
// Turn LED on when we are connected
//digitalWrite(LED_PIN, HIGH);
}
// Perform an HTTP GET request to a remote page
bool getPage() {
// Attempt to make a connection to the remote server
if ( !client.connect(http_site, http_port) ) {
return false;
}
// Make an HTTP GET request
client.println("GET /sender.php HTTP/1.1");
client.print("Host: ");
client.println(http_site);
client.println("Connection: close");
client.println();
return true;
}
