* 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 |
