/*
 * This sample illustrates how to go back to deep sleep from the
 * deep sleep wake stub.
 *
 * Consider the use case of counting pulses from an external sensor,
 * where the pulses arrive at a relatively slow rate.
 *
 * ESP32 is configured to go into deep sleep mode, and wake up from
 * a GPIO pin connected to the external pulse source.
 * Once the pulse arrives, ESP32 wakes up from deep sleep and runs
