Hi ,Dialog:
Our device need a long time to sleep,and it will wake up by a button interrupt. We set the sleep mode into ARCH_EXT_SLEEP_ON ,and the device will sleep as long as several months, we want to know if the device can keep sleep and do not reset or crash out, and if the button can wake up the device after such a long time ?
thanks.

Hi hm,
Be aware that the DA14585 will not reset if you do not implement such a functionality. So, there is no limit how long you keep it in extended sleep as long as there is still battery power.
Thanks, PM_Dialog
