Issues when adding a real time task

[Fluffy_Port]

I had a simple code to my project for the ESP32 that basically SCAN Wifis nad then allows you to connect to any of the networks selecting the SSID and password. Works perfectly until i decied to add a real time task that cheks every 500 ms if the connection is still active and print something (simple as that).

Code: Select all

xTaskCreatePinnedToCore(
check_net,
“check_net”,
2000,
NULL,
2,
NULL,
0);
void check_net(void * parameter){
if(WiFi.status()!=WL_CONNECTED) Serial.println(“Conexión perdida.Reconectando…”);
else Serial.println(“Todo en orden jefe WOF WOF.”);
vTaskDelay(5000/portTICK_PERIOD_MS);
}

Now the issue I find is that as soon as the task activates I get this in the terminal:

Code: Select all

I have no idea how to solve this. I tried to switch between cores or change the stack size but the problem still exist. I’d apreciate any help. Thanks.

Try increasing the allocated amount of stack, for one.

I changed it from 2000 to 10000 and I even tried with less. The problem wasn't solved.

Ah, never mind. I see that your task does not contain an infinite loop. Task functions cannot just return, they either need to run forever (while(1)) or use vTaskDelete(NULL) to delete themselves.

Thanks very much for your help. I thought I replied but it seems it totally went over my head.
