我正在尝试将我的ESP8266 NodeMCU连接到我的Mobile Hotspot Wifi
当我尝试使用笔记本电脑连接到ESP Wifi时，它说无线连接，没有互联网接入 . 这意味着，ESP正确获取Wifi_SSID和密码 .
为什么ESP无法连接到互联网？
我使用Arduino IDE将代码上传到ESP8266 . 我已将以下代码上传到ESP8266 .
#include <FirebaseArduino.h>
#include <ESP8266WiFi.h>
// Set these to run example.
#define WIFI_SSID "OnePlus3"
#define WIFI_PASSWORD ""
#define FIREBASE_DB_URL "https://my_db_url.firebaseio.com/"
#define FIREBASE_DB_SECRET_KEY "fakezaSyDsdadasddwGClaAy8ltYgywwo6i_VzXgY"
void setup() {
Serial.begin(115200);
pinMode(D1, OUTPUT);
pinMode(D2, OUTPUT);
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
}
Firebase.begin(FIREBASE_DB_URL, FIREBASE_DB_SECRET_KEY);
Firebase.stream("/automation");
}
void loop() {
if (Firebase.failed()) {
Serial.println("streaming error");
Serial.println(Firebase.error());
}
if (Firebase.available()) {
FirebaseObject event = Firebase.readEvent();
String eventType = event.getString("type");
eventType.toLowerCase();
Serial.print(eventType);
if (eventType == "put") {
String path = event.getString("path");
String data = event.getString("data");
if (path.equals("/fan/value")) {
if (data.equals("off")) {
digitalWrite(D1, HIGH);
} else {
digitalWrite(D1, LOW);
}
} else if (path.equals("/light/value")) {
if (data.equals("off")) {
digitalWrite(D2, HIGH);
} else {
digitalWrite(D2, LOW);
}
}
}
}
}
