Issue with token requesting.

Connecting to Wi-Fi.

Internet is stable. Still getting this issue?

The reasons can be your WiFi AP does not have the internet connectivity or the server is not valid.

First, try to reset router, change WiFi AP or connect via mobile WiFi hotspot.

Then, run this example to test your internet connection.

In Arduino IDE, select board, ESP32 Dev Module, select Files > Examples > HTTPClient > BasicHttpsClient

If you can run above example, the internet is ok otherwise not ok.

If internet is ok, make sure the DATABASE_URL defined in the Firebase example sketch is valid.

This is where you get the DATABASE_URL or FIREBASE_HOST in old examples

Thank you, it has started to work. Thank you for your help.

Hey there, I am having trouble trying to push an array of short into the cloudfirestore, i guess i dont understand the syntax of it. Is there a snippet that can help?

You need to use Firebase ESP Client library This is the examples.

[msamoeed009]

js.set("fields/watt/doubleValue/", measurements[0]); js.set("fields/current/arrayValue/", data); //data is an array of type short

js.toString(content);

Serial.print("Create a document... ");

(Firebase.Firestore.createDocument(&fbdo, FIREBASE_PROJECT_ID, "" / databaseId can be (default) or empty /, documentPath.c_str(), content.c_str() )); Serial.printf("ok\n%s\n\n", fbdo.payload().c_str());

Using this example but getting errors

You should post the error,

[mobizt]

You need to post at the Firebase ESP Client repos instead of here.

Use Discussions to post the question as it is not the library issue.

[mobizt]

Make sure your code at line js.set is valid.

FirebaseJson supports values from these variable types included bool, int, float, double, String, pointer to const char, FirebaseJson object and array.

Other variable types e.g. short, uint8_t, int8_t, uint16_t, int16_t, uint32_t, int32_t, long, unsigned long are not supported in FirebaseJson.

FirebaseJson doc is here.

[mobizt]

The field value when you construct it with FirebaseJon should follow this API reference.

https://cloud.google.com/firestore/docs/reference/rest/v1/Value

You need to learn Firestore concept and its API from Firestore document and you should known it well before use the library.

[mobizt]

I can't provide Firebase products getting started or how to.

[msamoeed009]

Ok, I will check.

String documentPath = String((auth.token.uid).c_str());

for (int x = 0; x < LOCAL_MEASUREMENTS - 1; x++) { data[x] = measurements[x]; }

js.set("fields/watt/doubleValue/", measurements[0]);

js.set("fields/current/arrayValue/", data); //data is an array of String. (GETTING ERROR HERE)

js.toString(content);

Serial.print("Create a document... ");

(Firebase.Firestore.createDocument(&fbdo, FIREBASE_PROJECT_ID, "" / databaseId can be (default) or empty /, documentPath.c_str(), content.c_str ())); Serial.printf("ok\n%s\n\n", fbdo.payload().c_str()); // else Serial.println(fbdo.errorReason()); }

//ERROR

Invalid value at 'document.fields[1].value.array_value' ( type.googleapis.com/google.firestore.v1.ArrayValue), \"\"

You need to learn Firestore before use.

[mobizt]

If you understand the Firestore data structure well, you can create simple or complex data without the limit.

This is the example for create doc with field array

String content;
FirebaseJson js;

String documentPath = "test_collection/test_document";

for (size_t i = 0; i < 10;i++)
{
    String filedPath = "fields/test_array/arrayValue/values/[" + String(i) + "]/stringValue";
    String arrValue = "Hello World! " + String(i);
    js.set(filedPath.c_str(), arrValue.c_str());
}

js.toString(content);

Serial.print("Create a document... ");

if (Firebase.Firestore.createDocument(&fbdo, FIREBASE_PROJECT_ID, "", documentPath.c_str(), content.c_str()))
    Serial.printf("ok\n%s\n\n", fbdo.payload().c_str());
else
    Serial.println(fbdo.errorReason());

[msamoeed009]

Thanks a lot. I have not worked on C alot but have been using Firebase with dart, js and C# and never had issues. Sorry for the trouble.
