Firebase Arduino problem with sending datas

[lucassouza000]

Hi, i'm trying to send datas to Firebase Real Time Database, and im using FirebaseDemo Code. I've made all the configuration in Firebase, following all the staps, i've downloaded the library, all this correctly, but there is no sign of life in firebase, nothing is sent, can anybody help me, please? Is important to report that i already modified the FirebaseHttpClient to the new version, like others posts advises, so, i dont know how to fix that, thank you !!

Hi

Are you sure that Nodemcu is connected to firebase?

Use this inside your code to cross check.

int count =0;

void setup{// wifi etc.}

void loop()
{

  if (Firebase.failed())
  {
    Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
    Serial.println(Firebase.error());
    delay(10);
    Serial.println("Error connecting firebase!");
    count++;
    if (count == 10) {
      count = 0;
      ESP.reset();
    }

  return;
  }

Also update SSL fingerprint. https://www.grc.com/fingerprints.htm?domain=test.firebaseio.com

Hope it help.
