WiFiServer.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();
  }
}
