firebase-esp-client's Introduction

I'm engineer from Thailand.

I'm working on machine condition monitoring and vibration analysis.

The Industrial IoTs, data processing and data acquisition are the fields that I focused.

I develop and maintain the Arduino C++ opensource libraries for embedded devices.

One of my projects Firebase Arduino Client Library for ESP8266 and ESP32 wins the Google Open Source Peer Bonus Program.

The E-mail client library for Arduino project is the first E-mail client library in the Arduino platform that allows the embedded device to send and receive E-mail.

I'm ready to support and help for fixing the issues and answering the questions related to my libraries

firebase-esp-client's Issues

Support for Arduino with Ethernet?

Hi, I really like this package and was wondering if I could simply use it on an arduino with an ethernet shield? Probably swap teh Wifi.h library for Ethernet.h ?

BUG RTDB.deleteNode gives error "data type mismatch" even though it does delete the node from firebase as expected

Describe the bug
RTDB.deleteNode returns false and gives error "data type mismatch" even though it does delete the node from firebase as expected

To Reproduce

use Firebase.RTDB.deleteNode to delete a node from a Realtime Database
it returns false, and fbdo.errorReason() equals "data type mismatch" though the node I'm trying to delete does get deleted from the database

I will post an example demonstrating the issue below.

Expected behavior
I expected RTDB.deleteNode to return true when it functions properly and deletes from the database, not return false even when it functions. I would like to be able to detect when there is an issue with deleting from the database.

IDE and its version:

Arduino
Version 1.8.13

ESP Arduino Core SDK version

ESP32 1.0.6

code that demonstrates the issue: (based on examples/RTDB/Basic)

#include <WiFi.h>
#include <Firebase_ESP_Client.h>

//Provide the token generation process info.
#include "addons/TokenHelper.h"
//Provide the RTDB payload printing info and other helper functions.
#include "addons/RTDBHelper.h"

/* 1. Define the WiFi credentials */
#define WIFI_SSID "removed"
#define WIFI_PASSWORD "removed"

/* 2. Define the API Key */
#define API_KEY "removed"

/* 3. Define the RTDB URL */
#define DATABASE_URL "something-default-rtdb.firebaseio.com" //<databaseName>.firebaseio.com or <databaseName>.<region>.firebasedatabase.app

/* 4. Define the user Email and password that alreadey registerd or added in your project */
#define USER_EMAIL "[email protected]"
#define USER_PASSWORD "removed"

//Define Firebase Data object
FirebaseData fbdo;

FirebaseAuth auth;
FirebaseConfig config;

unsigned long sendDataPrevMillis = 0;

int count = 0;

void setup()
{

  Serial.begin(115200);

  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  Serial.print("Connecting to Wi-Fi");
  while (WiFi.status() != WL_CONNECTED)
  {
    Serial.print(".");
    delay(300);
  }
  Serial.println();
  Serial.print("Connected with IP: ");
  Serial.println(WiFi.localIP());
  Serial.println();

  Serial.printf("Firebase Client v%s\n\n", FIREBASE_CLIENT_VERSION);

  /* Assign the api key (required) */
  config.api_key = API_KEY;

  /* Assign the user sign in credentials */
  auth.user.email = USER_EMAIL;
  auth.user.password = USER_PASSWORD;

  /* Assign the RTDB URL (required) */
  config.database_url = DATABASE_URL;

  /* Assign the callback function for the long running token generation task */
  config.token_status_callback = tokenStatusCallback; //see addons/TokenHelper.h

  //Or use legacy authenticate method
  //config.database_url = DATABASE_URL;
  //config.signer.tokens.legacy_token = "<database secret>";

  Firebase.begin(&config, &auth);

  Firebase.reconnectWiFi(true);
}

void loop()
{
  if (Firebase.ready() && (millis() - sendDataPrevMillis > 15000 || sendDataPrevMillis == 0))
  {
    sendDataPrevMillis = millis();

    Serial.printf("Set int... %s\n", Firebase.RTDB.setInt(&fbdo, "/test/int", count) ? "ok" : fbdo.errorReason().c_str());
    delay(5000);
    Serial.printf("Delete node %s\n", Firebase.RTDB.deleteNode(&fbdo, "/test/int") ? "ok" : fbdo.errorReason().c_str());
    //the above line prints "Delete node data type mismatch" even though it deletes the value int.

    count++;
  }
}

result of running code:

Connecting to Wi-Fi........
Connected with IP: 10.0.0.14

Firebase Client v2.3.7

Token info: type = id token, status = on request
Token info: type = id token, status = ready
Set int... ok
Delete node data type mismatch
Set int... ok
Delete node data type mismatch

A value is added and deleted from the database, as I would expect.

Please ask me if there's any more information I could provide, and thank you so much for writing and supporting so many useful libraries!

printResult function definition and location

I have gone through rtdb examples which uses function printResult(fbdo2) frequently but i dont see where it is located

getInt function takes a lot of time

Hello mobizt. I'm using your library and it made my project a lot better. However I'm having a little bit of trouble with getInt function.

I'm trying to read a simple integer value (varies from 0 to 100 by the way) on the Realtime Database and it sometimes takes less than a second to procces and sometimes it takes more than 10 seconds to read a single value. I don't really have a lot of experience with Firebase so I'm sorry if I'm doing something wrong.

Is there a way that I can make the procces faster or set the timeout correctly. I tried setReadTimeout function but it does not affect anything at all.

My code is too long so I'm just sharing the Firebase related parts so please let me know if something is missing.

#include <Firebase_ESP_Client.h>

int fanspeed;

#define DATABASE_URL ""
#define DATABASE_SECRET ""

FirebaseData firebaseData;
FirebaseAuth auth;
FirebaseConfig config;

void setup() {
  config.database_url = DATABASE_URL;
  config.signer.tokens.legacy_token = DATABASE_SECRET;

  Firebase.begin(&config, &auth);
  Firebase.reconnectWiFi(true);
  Firebase.RTDB.setReadTimeout(&firebaseData, 100);
}

void loop(){
    if(Firebase.ready())
    {
      Firebase.RTDB.getInt(&firebaseData, "/cYTdHBtkME/fanspeed2",&fanspeed);
    }

    Serial.print("Fan Speed: ");
    Serial.println(fanspeed);
}

HELP: Is the connection restarting?

Hi!
Today i was testing my code, that reads and writes in a Realtime database in Firebase, and I wrote in the plataformio.ini file the following:
build_flags = -DCORE_DEBUG_LEVEL=ARDUHAL_LOG_LEVEL_DEBUG
I saw how it works and the logs that are in the whole code, and I got surprised because each ~30 seconds, the following line appears:
[I][fb_ssl_client32.cpp:192] start_ssl_client(): WARNING: Use certificates for a more secure communication!
My code is running perfectly, but this means that the ssl connection restarts? I don't thing that is a problem, but in Firebase docs, they suggest to mantain the connection open, but maybe 30 seconds is the limit.

Another question I have is if I have to worry about the message WARNING: Use certificates for a more secure communication!. Should I use certificates for a more secure communication? How can I do it with Firebase?

And my las question: I've been supervising the usage of the realtime database, and this line:
Firebase.RTDB.getInt(&fbdo, path.c_str()) (is executed twice per second and its purpose is to hear for changes in a path that contains an Int. Is there a more efficient way to do it?)
This line downloads about 2,4 MB per hour from the databse. Is that too much? This big quantity of bytes can be related to the problem of the restarting connection, because in Firebase docs says:
These frequent, short-lived connections can actually add up to more connection costs, database load, and outbound bandwidth than live real-time connections to your database..

Create Firestore document inside HTTP_GET request inside void setup ()

Hi, I'm trying to create a Firestore document with HTTP_GET request

server.on("/temp", HTTP_GET, [](AsyncWebServerRequest *request) {
String content;
  FirebaseJson js;

  String documentPath = "sensors/temp";

  js.set("fields/value/integerValue", String(temp).c_str());
  js.toString(content);

Serial.println("------------------------------------");
Serial.println("Create a document...");

  if (Firebase.Firestore.createDocument(&fbdo, FIREBASE_PROJECT_ID, "" /* databaseId can be (default) or empty */, documentPath.c_str(), content.c_str()))
  {
    Serial.println("PASSED");
    Serial.println("------------------------------------");
    Serial.println(fbdo.payload());
    Serial.println("------------------------------------");
    Serial.println();
  }
  else
  {
    Serial.println("FAILED");
    Serial.println("REASON: " + fbdo.errorReason());
    Serial.println("------------------------------------");
    Serial.println();
  }

    request->send(200, "text/plain", "Hello, world");
});

but I get this error

------------------------------------
Create a document...

REASON: not connected
------------------------------------

Not finding any document

Hi,

I receive 404 not found on Firebase.RTDB.get / set even though I can see the document in the path. Here's what I'm using:

#include <Firebase_ESP_Client.h>
FirebaseData fbdo;
Firebase.RTDB.setInt(&fbdo, "document", 1)

Any suggestions?

RTDB Stream (callback mode) missing updates

Describe the bug
We are using RTDB with callback mode for a project. When updates are sent very frequently (~100ms between updates) some of them are lost and never provided to the callback function.

To Reproduce
Steps to reproduce the behavior:

Go to examples/RTDB/Stream_Callback.ino
Configure all settings
Run it. We are using ESP32 from az-delivery
From some other device connected to the same realtime database, send a few updates under /Test/Stream node. See code below used in a test page, which sends updates to /Test/Stream/a0 to /Test/Stream/a9 every 100ms:

for(let i=0; i<10; i++) {
  setTimeout(function() {
     firebase.database().ref(`/Test/Stream/a${i}`).set(firebase.database.ServerValue.increment(1));
  }, 100*i);
}

Expected behavior
The ESP32 callback should be called and output the 10 updates:

Stream Data1 available...
STREAM PATH: /Test/Stream
EVENT PATH: /a0
DATA TYPE: int
EVENT TYPE: put
VALUE: 1

[9 more updates skipped]

Actual behavior
Some updates are missing / skipped, and never get provided to the callback function. See full output for one test with 10 updates:

Stream Data1 available...
STREAM PATH: /Test/Stream
EVENT PATH: /a0
DATA TYPE: int
EVENT TYPE: put
VALUE: 1

Stream Data1 available...
STREAM PATH: /Test/Stream
EVENT PATH: /a4
DATA TYPE: int
EVENT TYPE: put
VALUE: 1

Stream Data1 available...
STREAM PATH: /Test/Stream
EVENT PATH: /a7
DATA TYPE: int
EVENT TYPE: put
VALUE: 1

Stream Data1 available...
STREAM PATH: /Test/Stream
EVENT PATH: /a9
DATA TYPE: int
EVENT TYPE: put
VALUE: 1

Screenshots
N/A, output provided above

Additional context

This was tested with Stream_Callback (not removing updates from that code), but all callbacks should be sent between updates from Callback. Removing those doesn't solve the issue.
Depending on the test different updates are missed.
Changing timeout between updates to 500ms all updates are sent to the callback in my tests.
Changing timeout between updates to 300ms some updates start to be lost, but less frequently than with 100ms.
Other Firebase integrations (ie. web) get all the updates, so they are ok in Firebase.

add more than 2 FirebaseData

when i use more than 2 FirebaseData it show an error "not connected" please help i need to use more than 2 FirebaseData

eventType always returns put, also when database entry is deleted

i'm trying to recognize in a rtd stream when an item gets added or deleted, but I can't tell which is which because eventtype is always "put"

Compile error - Missing files

I get the following error compiling with Arduino IDE for my AI Thinker ESP32-CAM:

Firebase_ESP_Client.h:38:26: fatal error: rtdb/FB_RTDB.h: No such file or directory

I'm guessing maybe the rtdb folder was never committed and added to the repository with the refactor between 1.0.3 and 1.1.1. The issue does not exist on 1.0.3

Recommended memory settings in ESP8266 Arduino Core SDK v3.0.0

Arduino IDE

When you update the ESP8266 Arduino Core SDK to v3.0.0, the memory can be configurable from Arduino IDE board settings.

By default MMU option 1 was selected, the free Heap can be low and may not suitable for the SSL client usage in this library.

To increase the Heap, choose the MMU option 3, 16KB cache + 48KB IRAM and 2nd Heap (shared).

More about MMU settings.
https://arduino-esp8266.readthedocs.io/en/latest/mmu.html

PlatformIO IDE

When Core SDK v3.0.0 becomes available in PlatformIO,

By default the balanced ratio (32KB cache + 32KB IRAM) configuration is used.

To increase the heap, PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM48_SECHEAP_SHARED build flag should be assigned in platformio.ini.

At the time of writing, to update SDK to v3.0.0 you can follow these steps.

In platformio.ini, edit the config as the following

[env:d1_mini]
platform = https://github.com/platformio/platform-espressif8266.git
build_flags = -D PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM48_SECHEAP_SHARED
board = d1_mini
framework = arduino
monitor_speed = 115200

Delete this folder C:\Users\UserName\.platformio\platforms\espressif8266@src-?????????????
Delete .pio and .vscode folders in your project.
Clean and Compile the project.

The supportedd MMU build flags in PlatformIO.

PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM48
16KB cache + 48KB IRAM (IRAM)
PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM48_SECHEAP_SHARED
16KB cache + 48KB IRAM and 2nd Heap (shared)
PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM32_SECHEAP_NOTSHARED
16KB cache + 32KB IRAM + 16KB 2nd Heap (not shared)
PIO_FRAMEWORK_ARDUINO_MMU_EXTERNAL_128K
128K External 23LC1024
PIO_FRAMEWORK_ARDUINO_MMU_EXTERNAL_1024K
1M External 64 MBit PSRAM
PIO_FRAMEWORK_ARDUINO_MMU_CUSTOM
Disables default configuration and expects user-specified flags

Test code for MMU

#include <Arduino.h>
#include <umm_malloc/umm_heap_select.h>

void setup() 
{
  Serial.begin(74880);
  HeapSelectIram ephemeral;
  Serial.printf("IRAM free: %6d bytes\r\n", ESP.getFreeHeap());
  {
    HeapSelectDram ephemeral;
    Serial.printf("DRAM free: %6d bytes\r\n", ESP.getFreeHeap());
  }
}

void loop() {
  // put your main code here, to run repeatedly:
}

Filesystem should be a user choice

First of all, thank you!
I really like your great work with this library.

I'm doing some tests with Cloud Storage and I find it really inconvenient to have to change the filesystem at the library level and not in the user sketch.
I faced the same problem in some of my libraries and solved it passing the filesystem as parameter in the class contructor and by directly using a pointer to the parent class Stream when file access is needed (like upload for example).
This way you don't have to change the definitions in the library source every time.

Maybe this approach can be applied also to your work?

I have looked for examples,
I try use FirebaseJsonData or fbdo.jsonString() but the result is empty.

    FirebaseJsonData jsonData;
    FirebaseJson js = fbdo.jsonObject();

    for (int i = 0; i < relays_length; i++) {
        js.get(jsonData, "relay-" + String(i));
        if (jsonData.success) {
            data[i] = jsonData.stringValue;
        }
    }
    //or
    Serial.println(fbdo.jsonString());

I need get key value. And when i try update the document with update mask, it print failed Invalid property path \"relay-0\".

Can you help me with the optimal solution.

please help me am using platfomio i get this error token is not ready

HELP Token is not ready

For some reason, custom tokens are taking a long time to be generated. I checked my router, but it seems fine. I tried using different esp32 boards, and they have the same issue. On the first run, it's instantaneous; however, after reboot it takes around 2 minutes to be generated. What can I do to make the process faster?

My general scheme for my project is as follows:

I have an android app that creates a user and sends the UID to the esp32
esp32 uses the UID to generate a token.
esp32 waits for the "token ready" event in the callback
esp32 uses the real-time database.

Sometimes, another issue that occurs is that my firebase project's website gets slower and my phone takes a while to sign in to firebase while the esp32 is generating a custom token.

HELP - REASON: INVALID_PASSWORD

I'm trying to use the Stream example from the Firebase_ESP_Client library and the following error is happening:

Where do I need to validate the email and password to use in the code?

Infinite loop using login with email and password

Good afternoon.
I'm having a problem connecting using the email and password method.
I'm stuck in this loop:

Firebase-ESP-Client/src/signer/Signer.cpp

Line 613 in 704a295

while (!complete)

chunckBufiSise is always = zero, so it doesn't leave the loop.
I'm using the code ---> examples ---> Firebase_esp_client ---> authentications ---> Email_Password

will it be a bug, or am i doing something wrong?
thanks.

Send_Message examples throw missing header files error (ESP8266)

Hey, Im using Arduino Uno to program ESP8266 to send messages to my phone via FCM.
After inserting all keywords i got the following error for both the legacy and HTTPv1 examples:

C:...\Firebase-ESP-Client-main\src/Firebase_ESP_Client.h:42:17: fatal error: No such file or directory
#include <ETH.h>

I editet the file "Firebase_ESP_Client.h", so that ETH.h will not be imported. The program compiled properly.
I got it working for the HTTPv1 Protocol, but not for legacy, but its possible that there are non related problems.

Firestore: Store Float/Double value | create document with auto id

Hey, thanks for providing this tool, it's really awesome!

I just struggle with two points:
Running the Create_Documents.ino works fine for me. But now I want to store float/double values instead of int/bool. I could not find any documentation on that in your repository and the google docs. Could you help me out there?

Also the 2nd question is regarding creating a new document. In your example you have a counter and provide firebase with your own unique id. In my case I want to have multiple devices writing to the same Firebase and need to use the auto id generation therefore. Could you tell me how the syntax is for this here as well? Could not find this in the docs either.

Do you have a general approach of transferring js code syntax to your plugin? I'm quite familiar using firestore with js...

Thanks in advance!

Keep the good work up!

Can use set() and pathExisted()

Describe the bug
after V2.0.7 I can't verify a pathExisted() and can't publish a array on a RTDB.

To Reproduce
Firebase.RTDB.pathExisted(&fbdo2, Path.c_str())
this function is retuning "1" with a path that do not exists.

Firebase.RTDB.set(&fbdo2, Path.c_str(), relayConfig);
this function returns "Invalid data; couldn't parse JSON object, array, or value."

Two questions about this library and realtimes simultaneos connections

Greetings, first I'd like to say thanks for this library.
After reading the docs I have two matters unclear.

If I listen to changed on two nodes for example with multipath, would this count on firebase as 2 simultaneous connections? Or only 1
If I update some values of a node for example with setInt and be done with it, would this count as a connection? As Im not using a stream? Then I would be able to do as many continuous updates no matter connections only data transfer (As example blaze plan is 200k max connections)

Best regards

Is it possible to implement onDisconnect for Firebase RTDB?

Hi @mobizt, thanks for such an amazing library.

I was wondering if it's possible to add onDisconnect functionality to Firebase RTDB.

HELP - with downloading large files from firebase storage using esp32

I am trying to download large files (1-5 MB's) from my firebase storage onto an SD card through the esp32. When I use the examples for downloading files from firebase storage and cloud storage, only a very small fraction of the files actually download. However, when I try to upload the files from the SD card into firebase storage, everything works.

I've read that the files will need to be sent over in chunks, but I do not know how to implement that or if this library is capable of doing that. Any help or pointers would be greatly appreciated!

Whoops. Looks like I created this post using my work account. Sorry about that.

Looking for an example on usage of ArrayValue for Firebase.Firestore.patchDocument

I am trying to update a key with an array, but having some trouble.

Can you please provide some example usage for this data type: https://firebase.google.com/docs/firestore/reference/rest/v1beta1/ArrayValue ?

My use case is adding logging data over time in batches of numbers.

Question

I am using firebase realtime database and example "AutomaticPlantWatering.ino". Compilation gives following error

sketch\AutomaticPlantWatering.ino.cpp.o:(.literal._Z5setupv+0x88): undefined reference to bool FB_RTDB::set<FirebaseJsonArray>(FirebaseData*, char const*, FirebaseJsonArray)' sketch\AutomaticPlantWatering.ino.cpp.o: In function setup()':

Also when i want to use following function
FirebaseData fbdo1;
FirebaseData fbdo2;
Firebase.RTDB.set(&fbdo2, path + "/Dimmer" + j + "Speed", 0);

program throw following error
no matching function for call to 'FB_RTDB::set(FirebaseData*, StringSumHelper&, int)'

Please help and at least add one example to set and read a variable from realtime database

failed with create/get/patch documents

Hello, mobizt, at first thanks you for providing such a complete Firebase lib, and here i test the Firestoreexample in last few days but i get the error.

Then i found the problem is the example code miss the setting config of host and api_key, as the follows.

config.host = FIREBASE_HOST;
config.api_key = API_KEY;

But in few days i try to modify the create_documents example that will create a documents 5 min a period, and then it cannot correctly upload a documents to Firestore.
As same as i change the period for 3(or 4) min, and it's works well.
I try to add the httpcode at the failed part, and it got 200 when uploads failed, so i guess the main problem may be that the Firebase connection will lost due to idle too long. So how can avoid this problem?

Here is my test code

get functions are slow?

Hi,
Any reason why the code snip below takes seconds to process?
On the previous version its pretty much instant.

if (Firebase.RTDB.getInt(&FBdata, Path.c_str())) {......

Many thanks

Firebase callFunction returns bad request when you add json data input.

Describe the bug
When using the firebase call function, adding data input returns bad request response from firebase. Two variations of this are observed.

Json data input returns bad request 400 result from firebase server.
When you just enter text and it succeeds, the req.body.data does not contain the data sent from the ESP32

Code:

FirebaseJson json;
json.set("data/message", "Some text data example.");
json.set("data/token", "Example of token data.");

String data;
json.toString(data, true);

// Serial.println(data.c_str());

if (Firebase.Functions.callFunction(&fbdo, FIREBASE_PROJECT_ID, PROJECT_LOCATION, "getAudio", data.c_str()))
{
  Serial.printf("ok\n%s\n\n", fbdo.payload().c_str());

}

To Reproduce
Steps to reproduce the behavior:

Run code snipper example provoked above. You will get a bad request response.
Replace the data.c_str() with just a plain string constant, and you also get a bad request reply.

Expected behavior
Json objects converted into string constants should appear as part of req.body.data object in cloud functions.

Screenshots
If applicable, add screenshots to help explain your problem.

PlatformIO - 5.1.1

Additional context
Can you also confirm if the library supports compatibility with both the cloud function onRequest and onCall functions.

Delay required to avoid "token is not ready"

Describe the bug
I tried forever to make the Beginner_Start_Here work, but kept getting "token is not ready".

I finally added a 3000ms delay here:

Firebase-ESP-Client/examples/RTDB/Beginner_Start_Here/Beginner_Start_Here.ino

Line 75 in a602918

I'm not sure if there's a callback available for Firebase.begin. A 3000ms delay doesn't sound like the right way to fix this, but it does work around the problem. I'd love it if you could give this a look and see if there's a better way to address the problem. Thank you!

StoreProhibitedCause Exception using the example Storage/List_Files.ino

Describe the bug
I've tried the example List_Files.ino with the ESP8266 Wemos D1 Mini Lite but during the request it throws an exception (output at the end).

To Reproduce
Steps to reproduce the behavior:

Open the example List_Files.ino
Set all your Wifi and Firebase credentials.
Upload and run
See error

Additional information

The Storage is working properly, I've used another Firebase.Storage functions like .getMetadata(...) and .upload(...) without problems.
Only the Wifi and Firebase credentials are the modified parts of the example, the rest of the code is the same
I just have 23 files on the Firebase Storage, the names are using 8.3 filename convention (from SD)
I dont know if this might help but according to a bunch of Serial prints, the exception could be happening at line 596 of FCS.cpp (json.get function)

Firestore update

hello,

first many compliments for the library.

As I'm using Firestore I would like to ask if stream , that in Firestore are realtime updates, are supported

thanks

Support files from SD Card for Firebase.Storage.upload(...) and .download(..) functions

I found that the function bool FB_CloudStorage::fcs_sendRequest(FirebaseData *fbdo, struct fb_esp_fcs_req_t *req) inside src/storage/FCS.cpp doesn't have code for opening files from SD, it's hardcoded for SPIFFS/LittleFS because it doesn't care about the storageType value (of the req struct).

That's all :)

Updating timestamp in Firestore Document - Suggestion

First of all, we want to say thank you @mobizt for bringing this library. It's making the development life easier. Currently, we are facing a problem in updating the timestamp field of type timestampValue in firestore document.

We checked that timestamp field of type timestampValue is coming during Get document but we are not able to Update timestamp field in the same type. Can you please suggest/share code snippet on how to update the timestamp field using this library.

Below is the code snippet we are using:

void updateDataToFirestore() {

  timeClient.update();
  unsigned long unix_epoch = timeClient.getEpochTime(); //unix_epoch holds unix time in milliseconds

  String content;
  FirebaseJson js;

  String documentPath = "school inout/west bengal/howrah/711101/wb0001/2020-2021/students/inouts_id2";

  js.set("fields/timestamp/timestampValue", unix_epoch); //undefined reference issue coming during compile time
  js.set("fields/timestamp/timestampValue", DateTime(unix_epoch*1000));  // issue coming during compile time
  
  js.toString(content);

  Serial.println("------------------------------------");
  Serial.println("Update a document...");

  /** if updateMask contains the field name that exists in the remote document and 
   * this field name does not exist in the document (content), that field will be delete from remote document
   */

  if (Firebase.Firestore.patchDocument( & fbdo, FIREBASE_PROJECT_ID, "" /* databaseId can be (default) or empty */ , documentPath.c_str(), content.c_str(), "timestamp" /* updateMask */ )) {
    Serial.println("PASSED");
    Serial.println("------------------------------------");
    Serial.println(fbdo.payload());
    Serial.println("------------------------------------");
    Serial.println();
  } else {
    Serial.println("FAILED");
    Serial.println("REASON: " + fbdo.errorReason());
    Serial.println("------------------------------------");
    Serial.println();
  }
}
