WiFi.SSID()

Description

Gets the SSID of the current network

Syntax

WiFi.SSID();
WiFi.SSID(wifiAccessPoint)

Parameters

wifiAccessPoint: specifies from which network to get the information

Returns

A string containing the SSID the WiFi shield is currently connected to.

string containing name of network requested.

Example

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

//SSID of your network
char ssid[] = "yourNetwork";
int status = WL_IDLE_STATUS;     // the Wifi radio's status

void setup()
{
  // initialize serial:
  Serial.begin(9600);

  // scan for existing networks:
  Serial.println("Scanning available networks...");
  scanNetworks();

  // attempt to connect using WEP encryption:
  Serial.println("Attempting to connect to open network...");
  status = WiFi.begin(ssid);

  Serial.print("SSID: ");
  Serial.println(ssid);

}

void loop () {}

void scanNetworks() {
  // scan for nearby networks:
  Serial.println("** Scan Networks **");
  byte numSsid = WiFi.scanNetworks();

  // print the list of networks seen:
  Serial.print("SSID List:");
  Serial.println(numSsid);
  // print the network number and name for each network found:
  for (int thisNet = 0; thisNet<numSsid; thisNet++) {
    Serial.print(thisNet);
    Serial.print(") Network: ");
    Serial.println(WiFi.SSID(thisNet));
  }
}
