Arduino nano 33 iot no sleep mode

Projects Programming
1

I make an application that records temperatures every x minutes, the problem I see is that the arduino goes to sleep. Is there a way to disable this function?

#include <avr/interrupt.h>
#include <avr/power.h>
#include <avr/sleep.h>
#include <avr/wdt.h>

I found these libraries to add but I always get an error when installing the zips I find.

With this watch my project is falling apart, if anyone has a solution.
Maybe using one pin out and one pin in and sending a signal every x minutes could prevent the watch?

Thank you in advance for your help

The Arduino never sleeps without being told so.

These aren't libraries but part of the platform core (think of it being part of the IDE). So you don't have to install any ZIP.

As we have no clue what project you're talking about and why it should fall apart we cannot help here.

If the arduino stops it means that it has an error and it crashes.
I'm going to look into this.
I put the code here. I do have ideas like writing to a file, my generated web page that may be causing my problem.
Thanks for your help

It seems that it is sending to the other arduino that blocks the program, I have to adjust the frequency of sending

The various tests carried out seem to show that it was the high frequency of sending packets to the other arduino.

Thanks for your help (knowing that the standby should be enabled)
