Clearification

Hi jawilson,

Within the print_wakeup_reason() function:

void print_wakeup_reason() {
  esp_sleep_wakeup_cause_t wakeup_reason;
  wakeup_reason = esp_sleep_get_wakeup_cause();
}

The first line declares the variable wakeup_reason of type esp_sleep_wakeup_cause_t.
The second defines the value of this variable.

We could have written the equivalent in a single line:

void print_wakeup_reason() {
  esp_sleep_wakeup_cause_t wakeup_reason = esp_sleep_get_wakeup_cause();
}

Regards,
Steph
