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 <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(); } }
