Is there a limitation for the sleeping mode?

[pierrot10]

Hello
I am wondering if AdruinoLowPower can put in sleep mode my board during 1 hour?
If not what's the limitation?

Actually, I make a loop which make sleep my board 5sec, wake up to quickly flash a led, sleep for 5 sec alternatively during one hour.

I would like to increase to 10 sec-

Does the ArduinoLowPower library work with Adafruit MO AMD21 with the LoRa module as well?

Thank

Hi @pierrot10 ,
there should be no such limitation. sleep(uint32_t milliseconds) internally calls rtc.setAlarmEpoch , so unless this one is bugged it should allow to sleep for almost 49 days (UINT32_MAX milliseconds).
If there's a problematic sketch, can you share it? The library works with all SAMD21 microcontroller based boards so it should be fine.
