You need to set one of the wake up interrupts to wake from Deep Sleep. That can be one of the Wake Up IO pins, the Alarm, or using one of the timed Deep Sleep functions, such as
Dash.deepSleepAtMostSec(sec); Pressing the reset button will also wake from Deep Sleep.
In Deep Sleep the processor is basically off, with only minimum circuitry enabled to detect a wake up event. Once you call a Deep Sleep function, code execution stops, so you can’t just make a wake-up call in software.
