Low-Power by rocketscream does not work

Hello everyone.

I was trying rocketscream's Low-Power library with an arduino nano ("old bootloader") and ide 2.1.0, specifically the powerDownWakeExternalInterrupt example but... I can't get it to work!

Could someone bring back a working example using an external interrupt?

Thanks

please don't double post

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Please create one topic only for your question and choose the forum category carefully. If you have multiple questions about the same project then please ask your questions in the one topic as the answers to one question provide useful context for the others, and also you won’t have to keep explaining your project repeatedly.

Repeated duplicate posting could result in a temporary or permanent ban from the forum.

Thank you.

Per your demandrequest I closed the thread in the Italian section and kept this one.

I’m not aware why the ide would mess up with the library, that seems a low probability. Just to be sure, have you tried with the latest 1.8 version ?

please read How to get the best out of this forum and post the code you are using and the exact wiring / hardware you have

The "old bootloader" is not compatible with the watchdog timer.
Try to load the optiboot bootloader thereby converting your Nano to a Uno as fas as the IDE is concerned. See: WatchDog on Arduino Nano - does not recover - Arduino Stack Exchange

Just a subtlety of the English language.
Demand in English comes across much more strongly that demander in French. Request would fit better here.

Eureka!

I had begun to suspect the bootloader but could not find any documentation on it about compatibility.

I will replace the bootloader and keep you updated.

Thank you

thanks - fixed
