migration from old lib

[jackSteav]

first of all thanks for your efforts for this lib and all other contributions

however in new lib. I can't find out how to implement same logic on stream here is the code used in old lib

void streamCallback(FirebaseStream data)
{
#ifdef ENABLE_DEBUG_MODE
    Serial.printf("sream path, %s\nevent path, %s\ndata type, %s\nevent type, %s\n\n",
                  data.streamPath().c_str(),
                  data.dataPath().c_str(),
                  data.dataType().c_str(),
                  data.eventType().c_str());
    printResult(data); // see addons/RTDBHelper.h
    Serial.println();
    // This is the size of stream payload received (current and max value)
    // Max payload size is the payload size under the stream path since the stream connected
    // and read once and will not update until stream reconnection takes place.
    // This max value will be zero as no payload received in case of ESP8266 which
    // BearSSL reserved Rx buffer size is less than the actual stream payload.
    Serial.printf("Received stream payload size: %d (Max. %d)\n\n", data.payloadLength(), data.maxPayloadLength());
    Serial.println();
#endif

    FirebaseJson *json = data.to<FirebaseJson *>();
// Print all object data
#ifdef ENABLE_DEBUG_MODE
    Serial.println((const char *)FPSTR("Pretty printed JSON data:"));
    json->toString(Serial, true);
    Serial.println();
    Serial.println((const char *)FPSTR("Iterate JSON data:"));
    Serial.println();
#endif

    size_t len = json->iteratorBegin();
    FirebaseJson::IteratorValue value;
    for (size_t i = 0; i < len; i++)
    {
        value = json->valueAt(i);
#ifdef ENABLE_DEBUG_MODE
        Serial_Printf((const char *)FPSTR("%d, Type: %s, Name: %s, Value: %s\n"), i, value.type == FirebaseJson::JSON_OBJECT ? (const char *)FPSTR("object") : (const char *)FPSTR("array"), value.key.c_str(), value.value.c_str());
#endif
        StreamHolder(value.key, value.value); // this is my logic handler (too speed there is nothing take much memory here) 
    }
    json->iteratorEnd();
    json->clear();
    dataChanged = true;
}

i found this discussion talk about same thing but it's too old, are you updated this part or something or just use arduino Json lib

and again thanks for your efforts it's insane .

As stated in documentation, the APIs and concept of this library and old libraries are different, and you cannot migrate from the old code. You can learn how to use it from provided examples and read the documentation thoroughly for the details.

thanks for your quick response, i will rewrite the code, i have 10 device uses old lib divided on 3 different databases, all of them suddenly cannot connected to firebase from 6 days, the mobile app work like perfect there is no update or change on db settings also there is no change on device codes, do you know why that happened ?! @mobizt

You have to debug by checking e.g. free heap, network, and server connection (internet).

In case low memory condition, SSL client may fail to connect to server.

In old library, the device time changes can affect the auth token expiration calculation which you should force it to refresh the token with Firebase.refreshToken(&config).

Edit:
server time changes -> device time changes

[jackSteav]

free heap is more than enough - network is fine
i will check Firebase.refreshToken

thanks for your support
