Sorry for the very late reply but have you looked at the sleep functions examples ?
Also ensure your firmware is up to date too as there were some improvements that came with that aspect.
Thank you for your reply. I've tried and retried and finally I solved the problem (remember: never put a delay in the interrupt function, if possible leave it empty).
Unfortunately all my efforts were useless, from here https://www.youtube.com/watch?v=wmWqkJ97Zsc&feature=youtu.be&t=822 seems possible to reduce the power consume up to only 0.5mA. I tried with the same sketch but I reach a minimum consume of 4-5mAh during sleep.
Do you know if it is possible to reach a so low power consume?
