ESP8266 D1 mini pro not connecting to firebase!
hello everyone, my code cannot connect to firebase. i used library : "https://github.com/FirebaseExtended/firebase-arduino" i tried to change fingerprint:
"B6 F5 80 C8 B1 DA 61 C1 07 9D 80 42 D8 A9 1F AF 9F C8 96 7D"
"6F D0 9A 52 C0 E9 E4 CD A0 D3 02 A4 B7 A1 92 38 2D CA 2F 26"
"E2 34 53 7A 1E D9 7D B8 C5 02 36 0D B2 77 9E 5E 0F 32 71 17"
but still same, cannot connect to firabase.
Everyone's who can help me how to fix this issue. thanks !
This my code:
#include <ESP8266WiFi.h> #include <FirebaseArduino.h>
#define FIREBASE_HOST ".firebaseio.com"
#define FIREBASE_AUTH "2MxjeR1XVtlvMWXTfdOv"
#define WIFI_SSID ""
#define WIFI_PASSWORD "*************"
String fireStatus = "";
int led = 14;
void setup() {
Serial.begin(9600);
delay(1000);
pinMode(LED_BUILTIN, OUTPUT);
pinMode(led, OUTPUT);
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.print("waitting...");
Serial.print(WIFI_SSID);
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
delay(500);
}
Serial.println();
Serial.print("connect to ");
Serial.println(WIFI_SSID);
Serial.print("IP : ");
Serial.println(WiFi.localIP());
Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
Firebase.setString("LED_STATUS", "OFF");
}
void loop() {
Firebase.setString("STATUS","TEST 11");
fireStatus = Firebase.getString("LED_11");
if (fireStatus == "ON" || fireStatus == "on") {
Serial.println("LED SANG");
digitalWrite(LED_BUILTIN, LOW);
digitalWrite(led, HIGH);
}
else if (fireStatus == "OFF" || fireStatus == "off") {
Serial.println("LED TAT");
digitalWrite(LED_BUILTIN, HIGH);
digitalWrite(led, LOW);
}
else {
Serial.println("Cannot conect");
}
}
I am getting same issue ,my code with d1 mini was woking properly but from 24-feb or 25-feb,it is not connected with firebase.
google has changed there certificate in february
this Line will fix it:
static const char kFirebaseFingerprint[] = "03:D6:42:23:03:D1:0C:06:73:F7:E2:BD:29:47:13:C3:22:71:37:1B"; // 2020-02
~Arduino/libraries/firebase-arduino-master/src/FirebaseHttpClient.h
thanks @tinoschroeter, it mean kFirebaseFingerprint is not static, sometimes change ?
@SmartTVVN yes, this will change after google set up a new certificate for this host... now its valid until: Feb 18 19:36:06 2021 GMT
you can check this by using openssl (HOSTNAME is your project name) echo | openssl s_client -showcerts -servername HOSTNAME.firebaseio.com -connect HOSTNAME.firebaseio.com:443 2>/dev/null | openssl x509 -inform pem -noout -text
or find the fingerprint: openssl s_client -connect HOSTNAME.firebaseio.com:443 < /dev/null 2>/dev/null | openssl x509 -fingerprint -noout -in /dev/stdin

Hello, the password has already changed, I do not understand the process to obtain the new password and I cannot find it anywhere
