light sleep mode, problem to disable gpio_wakeup pin

[natoop]

Hey,

I am able to activate light sleep mode with GPIO wake up source : esp_sleep_enable_gpio_wakeup()
i setup 2 pins to wake up from light sleep : gpio_wakeup_enable()

I have a problem when I try to deactivate on of the two GPIO pins with this function : gpio_wakeup_disable(gpio_num_tgpio_num)
But nothing happens, it has no effect.... someone knows how it works?

Code: Select all

void setup(){
  gpio_wakeup_enable(GPIO_NUM_37, GPIO_INTR_LOW_LEVEL);
  gpio_wakeup_enable(GPIO_NUM_39, GPIO_INTR_LOW_LEVEL); 
  esp_sleep_enable_gpio_wakeup();
}

void loop(){
  Serial.println("boucle loop");
  Serial.println("Boot number: " + String(Count));
  
  if (Count == 5){
    Serial.println("desactivation du  wakeup BUTTON_HOME");
    gpio_wakeup_disable(GPIO_NUM_37);
  }
    
  //Go to sleep now
  Serial.println("Going to sleep now in 2s");
  delay(2000);
  esp_light_sleep_start();
  Serial.println("BUTTON_HOME : ");
  Serial.println(digitalRead(GPIO_NUM_37));
  Serial.println("BUTTON_B : ");
  Serial.println(digitalRead(GPIO_NUM_39));
  if (digitalRead(GPIO_NUM_37)== LOW){
    Serial.println("Appui du BUTTON_HOME -> WakeUp");
  }
  if (digitalRead(GPIO_NUM_39)== LOW){
    Serial.println("Appui du BUTTON_B -> WakeUp");
  }
  
  //Print the wakeup reason for ESP32
  print_wakeup_reason();
  
  ++Count;
}

void print_wakeup_reason(){
  esp_sleep_wakeup_cause_t wakeup_reason;

  wakeup_reason = esp_sleep_get_wakeup_cause();
  Serial.println(wakeup_reason);
  switch(wakeup_reason)
  {
    case ESP_SLEEP_WAKEUP_EXT0 : Serial.println("Wakeup caused by boutton home A - 37"); break;
    case ESP_SLEEP_WAKEUP_EXT1 : Serial.println("Wakeup caused by boutton B - 39"); break;
    case ESP_SLEEP_WAKEUP_TIMER : Serial.println("Wakeup caused by timer"); break;
    case ESP_SLEEP_WAKEUP_GPIO : Serial.println("Wakeup caused by GPIO"); 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;
  }
  
}

Thanks for your help
