NUCLEO-L452RE-P deep sleep doesn't work

[Andrea]

LowPower.deepSleep doesn't work for me. It doesn't stop, execute the method and continue immediately no matter the value of "uint32_t ms". But LowPower.sleep() and LowPower.shutdown() work fine.
Below is the simple script with the details of the development environment.

Any suggestions?

#include "Arduino.h"
#include "STM32LowPower.h"

void setup() {
    // LED_BUILTIN is PB13 on NUCLEO-L452RE-P 
    pinMode(PB13, OUTPUT);
    delay(200);
    LowPower.begin();
}

void loop() {
    digitalWrite(PB13, HIGH);
    LowPower.deepSleep(5000);

    digitalWrite(PB13, LOW);
    LowPower.deepSleep(5000);

}

Hi @andreax64
I've tested and works as expected.
Seems you used PIO, we do not support it. Anyway, your config seems weird. You talk about NUCLEO-L452RE-P but your config seems to be for NUCLEO-L452RE (note the missing "-P") which is not the same board.
Nevertheless using Arduino IDE it works as expected and no need to use the PB13 as LED_BUILTIN is properly set to PB13 for NUCLEO-L452RE-P.
