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() { }
