Arduino WiFi101 - WiFi.scanNetworks()用法及代碼示例

WiFi.scanNetworks();

#include <SPI.h>
#include <WiFi101.h>

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

byte mac[6];                     // the MAC address of your Wifi shield


void setup()
{
 Serial.begin(9600);

 status = WiFi.begin(ssid);

 if ( status != WL_CONNECTED) {
    Serial.println("Couldn't get a wifi connection");
    while(true);
  }
  // if you are connected, print your MAC address:
  else {

  Serial.println("** Scan Networks **");
  byte numSsid = WiFi.scanNetworks();

  Serial.print("SSID List:");
  Serial.println(numSsid);
  }
}

void loop () {}
