Thank you very much for your answer. I tried your code on the post, and it works perfectly to wake up the device (Reset) with the IMU sensor. However, I am trying to do the same with a timer instead of the IMU.
For a better explanation, I want to:
Turn on the device → read and send a measurement (do something) → go to deep sleep → wake up after 10s (for example) → Repeat (reset).
Based on your experience, do you think this is possible with this board and the available libraries/configurations?
Thanks again for your help!
