Hi, I used the code of deep sleep in example code of the esp32 and I need to update on it. I need when the esp32 wake up for 5 seconds it printing some statement(My idea is keep printing the statement for five minutes), Is this code correct? or how can correct it, please?
#define uS_TO_S_FACTOR 1000000 /* Conversion factor for micro seconds to seconds */
#define TIME_TO_SLEEP 5 /* Time ESP32 will go to sleep (in seconds) */
RTC_DATA_ATTR int bootCount = 0;
void print_wakeup_reason(){
esp_sleep_wakeup_cause_t wakeup_reason;
wakeup_reason = esp_sleep_get_wakeup_cause();
switch(wakeup_reason)
{
case ESP_SLEEP_WAKEUP_EXT0 : Serial.println("Wakeup caused by external signal using RTC_IO"); break;
case ESP_SLEEP_WAKEUP_EXT1 : Serial.println("Wakeup caused by external signal using RTC_CNTL"); break;
case ESP_SLEEP_WAKEUP_TIMER : Serial.println("Wakeup caused by timer"); break;
case ESP_SLEEP_WAKEUP_TOUCHPAD : Serial.println("Wakeup caused by touchpad"); break;
case ESP_SLEEP_WAKEUP_ULP : Serial.println("Wakeup caused by ULP program"); break;
default : Serial.printf("Wakeup was not caused by deep sleep: %d\n",wakeup_reason); break;
}
}
void printing(){
Serial.println("While esp32 is wake up, I'll printing Hi");
}
void Deep_Sleep(){
//Increment boot number and print it every reboot
++bootCount;
Serial.println("Boot number: " + String(bootCount));
//Print the wakeup reason for ESP32
print_wakeup_reason();
esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP * uS_TO_S_FACTOR);
Serial.println("Setup ESP32 to sleep for every " + String(TIME_TO_SLEEP) +
" Seconds");
printing();
Serial.println("Going to sleep now");
// delay(1000);
Serial.flush();
esp_deep_sleep_start();
Serial.println("This will never be printed");
}
void setup(){
Serial.begin(115200);
delay(1000); //Take some time to open up the Serial Monitor
Deep_Sleep();
}
void loop(){
//This is not going to be called
}
