Data reading time as a variable

[Engine1992]

Hello,

I'm trying to figure it out and I can't come up with anything, namely that each time data is sent to the server, the reading time is also saved (or sent). I tried to get the time as a variable from the SIM800L module but without success.

Is there an option to send the variable to the server and have the date added at the Firestone level?

Somewhere I found an entry like

doc.add("updateTime", Values::Value(FieldValue.serverTimestamp()));

but I get the error: error:

'FieldValue' was not declared in this scope
doc.add("updatedate", Values::Value(FieldValue.serverTimestamp()));

Is there any other way to record the time of the last reading?

No such class and method you are using in this library.

For timestamp, you have to commit with write as in this example which is the only approach that Firestore API allows.
