Define the sleep time.

[alessandrolecce]

Is it possible to define sleep time? I need to sleep the Arduino for 5 minutes. How can I implement it in LowPower.idle() ?

Hi, I want to make the same thing as you. Have you found a solution to increase sleeping time?

Not, yet, I will work on it by the end of this month

This is exactly what I was coming to request too :)

Have you tried powerDown? sleepCounter represents 8s periods (due to SLEEP_8S). So 5 minutes would be sleepCounter = 38

for (int sleepCounter = 38; sleepCounter > 0; sleepCounter--) { LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF); }

That still means it's wakes up every multiple of 8 seconds. While this would be sufficient for most use cases, but it does not have a single defined sleep time with no wakes like the title mentions.

The timer is based on the watchdog timer which has discrete period that cannot be changed. Using the for loop is the only way here without any external RTC IC or upgrade to the newer megaAVR 0-series MCU that has real time counter.
