SSID()
描述 Gets the SSID of the current network
WiFi.SSID(); WiFi.SSID(wifiAccessPoint)
wifiAccessPoint: specifies from which network to get the information
A string containing the SSID the WiFi shield is currently connected to. string containing name of network requested.
#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));
