WiFi.RSSI()
描述
取得連線至路由器的訊號強度。
語法
WiFi.RSSI();
WiFi.RSSI(wifiAccessPoint);
參數
wifiAccessPoint
:指明要取得訊號強度的無線網路
回傳
long
:信號強度(RSSI),單位為 dBm
範例
#include <WiFi.h> // 無線網路的 SSID char ssid[] = "yourNetwork"; // WPA 的密碼 char pass[] = "secretPassword"; void setup() { WiFi.begin(ssid, pass); if (WiFi.status() != WL_CONNECTED) { Serial.println("Couldn't get a wifi connection"); while(true); } // 如果成功連上無線網路,印出相關資訊 else { // 印出訊號強度 long rssi = WiFi.RSSI(); Serial.print("RSSI:"); Serial.println(rssi); } } void loop () {}
