WiFi : Server class
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();
}
}
#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();
}
}
