描述

取得连线至路由器的讯号强度。

语法


WiFi.RSSI();
WiFi.RSSI(wifiAccessPoint);

参数

wifiAccessPoint：指明要取得讯号强度的无线网路

回传

long：信号强度(RSSI)，单位为 dBm

范例

#include <WiFi.h>

// 无线网路的 SSID
char ssid[] = "yourNetwork";
// WPA 的密码
char pass[] = "secretPassword";

void setup()
{
 WiFi.begin(ssid, pass);

  if (WiFi.status() != WL_CONNECTED) {
    Serial.println("Couldn't get a wifi connection");
    while(true);
  }
  // 如果成功连上无线网路，印出相关资讯
  else {
    // 印出讯号强度
    long rssi = WiFi.RSSI();
    Serial.print("RSSI:");
    Serial.println(rssi);
  }
}

void loop () {}
