connect()

Description

Connect to the IP address and port specified. The return value indicates success or failure. connect() also supports DNS lookups when using a domain name (ex: “google.com”).

Syntax


client.connect(ip, port)
client.connect(URL, port)

Parameters

ip: the IP address that the client will connect to (array of 4 bytes)
URL: the domain name the client will connect to (string, ex.: “arduino.cc”)
port: the port that the client will connect to (int)

Returns

Returns true if the connection succeeds, false if not.

Example

#include <WiFi.h>

char ssid[] = "myNetwork";          //  your network SSID (name) 
char pass[] = "myPassword";   // your network password

int status = WL_IDLE_STATUS;
char servername[]="google.com";  // remote server we will connect to

WiFiClient client;

void setup() {
  Serial.begin(9600);
  Serial.println("Attempting to connect to WPA network...");
  Serial.print("SSID: ");
  Serial.println(ssid);

  status = WiFi.begin(ssid, pass);
  if ( status != WL_CONNECTED) { 
    Serial.println("Couldn't get a wifi connection");
    // don't do anything else:
    while(true);
  } 
  else {
    Serial.println("Connected to wifi");
    Serial.println("\nStarting connection...");
    // if you get a connection, report back via serial:
    if (client.connect(servername, 80)) {
      Serial.println("connected");
      // Make a HTTP request:
      client.println("GET /search?q=arduino HTTP/1.0");
      client.println();
    }
  }
}

void loop() {

}
