Updating document (Firestore) - SSL Write error

[Engine1992]

Hey.

I create a document using Docs.createDocument and after that, I update the document using PatchDocumentOptions.

Code:

Creating document:

Values::DoubleValue distanceV(distance);
Values::DoubleValue voltageV(voltage);
Values::DoubleValue tempV(temp);

Document<Values::Value> doc("odleglosc", Values::Value(distanceV));
doc.add("napiecie", Values::Value(voltageV));
doc.add("temperatura", Values::Value(tempV));

Docs.createDocument(aClient, Firestore::Parent(FIREBASE_PROJECT_ID), documentPath, DocumentMask(), doc, asyncCB);

Updating document:

Values::DoubleValue distanceV(distance);
Values::DoubleValue voltageV(voltage);
Values::DoubleValue tempV(temp);

Document<Values::Value> doc("odleglosc", Values::Value(distanceV));
doc.add("napiecie", Values::Value(voltageV));
doc.add("temperatura", Values::Value(tempV));

PatchDocumentOptions patchOptions(DocumentMask("odleglosc,napiecie,temperatura") /* updateMask */, DocumentMask() /* mask */, Precondition() /* precondition */);

Docs.patch(aClient, Firestore::Parent(FIREBASE_PROJECT_ID), documentPath, patchOptions, doc, asyncCB);

First run always goes with no problems, everything is fine, but when the loop() try to update document secoud time, I get this message on Serial Monitor:

17:28:59.852 -> > ERROR.mUpdateEngine: Error writing to basic client.
17:28:59.852 -> > ERROR.connected: Not connected because write error is set.
17:28:59.852 -> > ERROR.connected: SSL Write error

17:29:25.059 -> Error msg: TCP receive time out, code: -3

Sometimes after that, code goes again and update document but not every time. Sametimes code freezes. What is the reason of this behavior?

I use SIM800L to connect to the internet by GPRS.

Your network is disconnected as seen from this message.
17:29:25.059 -> Debug msg: Connecting to server... >> Waiting for network... >> Network connected >> Connecting to internet >> GPRS/EPS connected

This should not happen, unless the poor network signal.

You should know that it is out of library control and GSM client handles this.

Ok, i check the network signal 👍 thanks a lot ;)
