I am using the code example in this page, Arduino-Nano-33-IoT-Ultimate-Guide/SavePowerRTC.md at 45e601ad5b7f255e385400d87164c21a09e8f6b4 · ostaquet/Arduino-Nano-33-IoT-Ultimate-Guide · GitHub
It works as expected if I copy the exact code of his to wake up once per min. Now I want to change to wake up once per hour. So I did some changes on this line,
Clock.setA1Time(1, 1, 1, 0, 0b1110, false, false, false);
to this below,
Clock.setA1Time(1, 1, 1, 0, 0b1100, false, false, false);
Or Clock.setA1Time(1, 1, 0, 0, 0b1100, false, false, false);
But both don't work - the board doesn't sleep for one hour.
How do I set the RTC? I don't need the exact time. I just need the arduino to wake up every hour.
Thanks in advance.
