WiFi - server.available()

Description

Gets a client that is connected to the server and has data available for reading. The connection persists when the returned client object goes out of scope; you can close it by calling client.stop().

available() inherits from the Stream utility class.

Syntax

server.available()

Parameters

None

Returns

a Client object; if no Client has data available for reading, this object will evaluate to false in an if-statement

Example

#include <SPI.h>
#include <WiFi.h>

char ssid[] = "Network";          //  your network SSID (name)
char pass[] = "myPassword";   // your network password
int status = WL_IDLE_STATUS;

WiFiServer server(80);

void setup() {
  // initialize serial:
  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");
    while(true);
  }
  else {
    server.begin();
    Serial.print("Connected to wifi. My address:");
    IPAddress myAddress = WiFi.localIP();
    Serial.println(myAddress);

  }
}

void loop() {
  // listen for incoming clients
  WiFiClient client = server.available();
  if (client) {

    if (client.connected()) {
      Serial.println("Connected to client");
    }

    // close the connection:
    client.stop();
  }
