Thanks for the great article about deep sleep, Is there an upper limit how long time you can set for deep sleep? I heard somethings like 70 minutes?
Thanks! You’re correct the maximum time is 71 minutes according to the official documentation, but I think we can put a condition in the Arduino IDE to check if the restart happened due to a RTC overflow (the timer surpassed the 71 minute mark).
I’ll be on holidays until the end of next week, and I’ll be checking the Arduino IDE library to find that function to check if it’s possible to do it.
Good! Sometimes it’s enough to report a value once a day which will make big difference
