webserver example
Posted: Wed Dec 30, 2015 6:25 pmHello
I tried an example about webserver
All is good with no problem of uploading
On serial port I found the following text ( all is connected ):
Connecting to My Wireless
...........................................
WiFi connected
Server started
Use this URL to connect: http://192.168.1.99/
When I entered the ip 192.168.1.99 always it's unreachable.
I tried ping 192.168.1.99 =>destination unreachable.
thank you
please help
I tried an example about webserver
Code: Select all
#include <ESP8266WiFi.h>
const char* ssid = "your-ssid";
const char* password = "your-password";
int ledPin = 2; // GPIO2
WiFiServer server(80);
void setup() {

delay(10);
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, LOW);
// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.print("Use this URL to connect: ");
Serial.print("http://");
Serial.print(WiFi.localIP());
Serial.println("/");
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){

digitalWrite(ledPin, HIGH);

}
if (request.indexOf("/LED=OFF") != -1) {
digitalWrite(ledPin, LOW);
value = LOW;
}
// Set ledPin according to the request
//digitalWrite(ledPin, value);
// Return the response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // do not forget this one
