Verification of data submission for retry / firestoreDB

[eeduu-ardo]

I am developing an application that sends a string of text to a Firestore database. My challenge arises from my poor internet connection. To mitigate this issue, I've implemented a connectivity routine that checks for an internet connection whenever I need to send data, which occurs every 24 hours. I am currently looking for a way to verify the error payload and implement a retry mechanism if the submission fails. How can I do it?

This is the part of my code that handles sending data

`bool SendFBData() {
if (year() < 2025) { return false; }
// document path creation of the day
String documentPath = String(Identifier);
documentPath += "/";
documentPath += docpef;
documentPath += "(LogDoc)";

// getting strings from eeprom
Values::StringValue WATER(preferences.getString("sensBurst"));
Values::StringValue STATUS(preferences.getString("statBurst"));
Values::StringValue TEMP(preferences.getString("tempBurst"));

DocumentValues::Value doc("TrtdWater", Values::Value(WATER));
doc.add("TimeO3ing", Values::Value(STATUS)).add("SensorTemp", Values::Value(TEMP));

// Operação crítica
Docs.createDocument(aClient, Firestore::Parent(FIREBASE_PROJECT_ID), documentPath, DocumentMask(), doc);

Serial.println(documentPath);

// Define a way to verify the submission status

/*if (error) = true;
return false;
else
return true
*/
return true;
}`

The examples already provided information you are asking for.

ooh, I had seen this example, but i ended up not noticing this detail.

I adapted it to look like this:

if (aClient.lastError().code() != 0) {
return false;
} else {
return true;
}

Thank you!!!
