Hi,
I use xTaskCreate and when I use it twice it works properly but when I add one more xTaskCreate then I have error:
[E][ssl_client.cpp:36] _handle_error(): [start_ssl_client():207]: (-32512) SSL - Memory allocation failed
[E][WiFiClientSecure.cpp:133] connect(): start_ssl_client: -32512

What can be reason of that ? It used the whole available memory ?

Code: [Select all] [Expand/Collapse]

  xTaskCreate(led,"led",6000,NULL,1,NULL);
  xTaskCreate(door,"door",6000,NULL,1,NULL);
  xTaskCreate(ledonoff,"ledonoff",6000,NULL,1,NULL);
 
 
 
void door(void *parameter)
{
  int pauzaPir = 100000;
 
  for(;;){
  fireStatusDoor = Firebase.getString("DOOR");                     
 
  
  if (fireStatusDoor == "Close") 
  {                         
    myservo.write(90);    
  }
                                                            
  else if (fireStatusDoor == "Open") 
  {                
    myservo.write(0);                                                        
  }
  else {
    Serial.println("Wrong Credential! Please send open/close");
    
  }
vTaskDelay(10);
}
vTaskDelete ( NULL );
}
 
 
 
void ledonoff(void *parameter)
{
  
 
  for(;;){
  fireStatusLed = Firebase.getString("LED_STATUS");  
 
  if (fireStatusLed == "ON") 
  {                         
    digitalWrite(led_1, HIGH);                                                         
  }
 
  else if (fireStatusLed == "OFF") 
  {             
    digitalWrite(led_1, LOW);  
  }
 
  else 
  {
    Serial.println("Wrong Credential! Please send ON/OFF");
    
  }
  vTaskDelay(10);
  }
  vTaskDelete ( NULL );
}
 
 
 
void led(void *parameter)
{
int led_r;
int led_g;
int led_b;
 
   
for(;;)
{
 
 
led_r=Firebase.getInt("LED_R");
 
 
 led_g=Firebase.getInt("LED_G");
  
led_b=Firebase.getInt("LED_B");
 
 
for (int i=0; i<num_led; i++){
    leds[i] = CRGB(led_r, led_g, led_b );
    
    FastLED.show();
   
  }
 vTaskDelay(10);
}
vTaskDelete ( NULL );
}

Don't think it should have as 3 tasks of 6K bytes each alone shouldn't be enough to consume all memory. You can call

Code: Select all

heap_caps_get_free_size()

in esp_heap_caps.h to get amount of free memory of a particular type/capability. Suggest you check the amount of memory with MALLOC_CAP_INTERNAL capability after each task creation to see if you are really running out of memory.
