我想通过esp8266卡连接到我的Firebase数据库。我尝试使用为Arduino提供firebase库的演示代码,但无法正常工作。我正确输入了wi-fi数据并可以建立连接,但是当我尝试连接到Arduino控制台的数据库时,出现以下错误:设置/编号失败:
#include <ESP8266WiFi.h>
#include <FirebaseArduino.h>
// Set these to run example.
#define FIREBASE_HOST "-.firebaseio.com"
#define FIREBASE_AUTH "----"
#define WIFI_SSID "----"
#define WIFI_PASSWORD "----"
void setup() {
Serial.begin(9600);
// connect to wifi.
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.print("connecting");
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
delay(500);
}
Serial.println();
Serial.print("connected: ");
Serial.println(WiFi.localIP());
Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}
int n = 0;
void loop() {
// set value
Firebase.setFloat("number", 42.0);
// handle error
if (Firebase.failed()) {
Serial.print("setting /number failed:");
Serial.println(Firebase.error());
return;
}
delay(1000);
// update value
Firebase.setFloat("number", 43.0);
// handle error
if (Firebase.failed()) {
Serial.print("setting /number failed:");
Serial.println(Firebase.error());
return;
}
delay(1000);
// get value
Serial.print("number: ");
Serial.println(Firebase.getFloat("number"));
delay(1000);
// remove value
Firebase.remove("number");
delay(1000);
// set string value
Firebase.setString("message", "hello world");
// handle error
if (Firebase.failed()) {
Serial.print("setting /message failed:");
Serial.println(Firebase.error());
return;
}
delay(1000);
// set bool value
Firebase.setBool("truth", false);
// handle error
if (Firebase.failed()) {
Serial.print("setting /truth failed:");
Serial.println(Firebase.error());
return;
}
delay(1000);
// append a new value to /logs
String name = Firebase.pushInt("logs", n++);
// handle error
if (Firebase.failed()) {
Serial.print("pushing /logs failed:");
Serial.println(Firebase.error());
return;
}
Serial.print("pushed: /logs/");
Serial.println(name);
delay(1000);
}
我想与我的Firebase数据库建立连接。
答案 0 :(得分:0)
如果FirebaseArduino版本的指纹过时,则会发生这种情况。
检查已安装的FirebaseHttpClient.h
中的指纹是否与当前指纹相对应。
