Issues when adding a real time task
Posted: Fri Feb 10, 2023 11:43 am
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).
Now the issue I find is that as soon as the task activates I get this in the terminal:
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.
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);
}
