WDT init compilation error

[Burdi60]

Board

ESP32-WROOM

Device Description

ESP32-WROOM module on a specific PCB, to format information received on a serial port and transmit it to a WEB server

Hardware Configuration

Nothing specific

Version

v3.0.1

IDE Name

Arduino IDE

Operating System

Windows 11

Flash frequency

80 MHz

PSRAM enabled

yes

Upload speed

115200

Description

In the latest versions of the ESP32 card manager (version 3.0.0 to 3.0.2), compiling the esp_task_wdt_init() function generates an error.
There are no compilation errors with earlier 2.0.X versions (2.0.17 for example).

Sketch

#include <Arduino.h>
#include <esp_task_wdt.h>

#define WDT_DELAI 54

void setup() {
  //
  // initialisation du watchdog
  //esp_task_wdt_init(WDT_DELAI, true);
  esp_task_wdt_init(WDT_DELAI, true);
  esp_task_wdt_add(NULL);

}

void loop() {

}

The API has changed. This is part of ESP-IDF, not arduino.

I use Arduino IDE and not ESP-IDF.
The ESP32 board driver is installed in the Arduino IDE application.
The compilation error is obtained in the Arduino IDE application and not ESP-IDF which I do not use.

But you are using ESP_IDF APIs. What you posted is NOT part of Arduino API, but from the underlying ESP-IDF that is included with Arduino

Closing as answered

[Burdi60]

So who should I report this bug to?
The compilation error is indeed generated by the Arduino-IDE compiler!!!
I was just asking for help, and you say I need to close the post. For what ?
Be a little more forthcoming in your answers!

[me-no-dev]

This is not a bug. Arduino has changed to new MAJOR version, which also changes the ESP-IDF's MAJOR version, which has changes in it's API. You need to implement the new API if you want your ESP-IDF code to work. @lbernstone has highlighted the updated header where you can read the new API.

Thank you for your reply.
Indeed, watchdog management on the ESP32 has been very significantly modified by ESPRESSIF.
I just modified my code and I no longer have any compilation errors.
