FALLING/LOW not working on bare 328 about sleep_n0m1 HOT 3 CLOSED

Hi, Did you figure out the problem? I am pretty sure LOW should work as well as HIGH without the external oscillator.

Maybe there is a problem with the pin change interrupt?

instead of this:
sleep.sleepInterrupt(digitalPinToInterrupt(SENSOR_PIN), FALLING);

try:
sleep.sleepInterrupt(0, FALLING); //number 0 (for digital pin 2) or number 1 (for digital pin 3)

Another thing to try is using LOW instead of FALLING.

Let me know if you can solve this. Thanks!

Hey thanks, this is related with the other issue about the calibration. The first calibration was happening = big consumption.
