描述

取得 WiFi Shield 的 MAC 位址。

语法


WiFi.macAddress(mac);


参数

mac：mac 是一个大小为 6 位元组的阵列，macAddress() 执行完后，会把 WiFi Shield 的 MAC 位址放到 mac 裡

回传

无回传值

范例

#include <WiFi.h>

char ssid[] = "yourNetwork";     // 无线网路的 SSID
int status = WL_IDLE_STATUS;     // 无线网路的状态

byte mac[6];                     // 存放 MAC 位址的阵列

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

 status = WiFi.begin(ssid);

 if ( status != WL_CONNECTED) {
    Serial.println("Couldn't get a wifi connection");
    while(true);
  }
  // 如果成功连线，印出 WiFi Shield 的 MAC 位址
  else {
    WiFi.macAddress(mac);
    Serial.print("MAC: ");
    Serial.print(mac[5],HEX);
    Serial.print(":");
    Serial.print(mac[4],HEX);
    Serial.print(":");
