Maximum time for deep sleep shield
I am using a WiPy 2.0 with a deep sleep shield. I have a random problem when the time in the go_to_sleep() method exceeds more or less the 300 seconds (5 min). The device wakes sometimes well and most of times, before the seconds programmed with a remarkable error. Below 300 secs, the wake time is very accurate. Does anyone know if the maximum time is a limitation in deep sleep shield?
Thanks and regards
