WiFi.RSSI()
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 () {}
