hello good afternoon, could anyone help me ?

I have the following error when trying to use the AsyncTCP library in a project with esp32;

.piolibdeps \ AsyncTCP \ src \ AsyncTCP.cpp: 201: 141: error: 'xTaskCreateUniversal' was not declared in this scope.

NOTE: I am using platformio id

Thank you.

Hello, It looks like you’re using an outdated library and that’s why is not compiling. Can you ensure that you update all the libraries and the ESP32 board add-on?

Tools > Board > Boards Manager: ESP32 board add-on: core version 1.0.2
Sketch > Include Library > Manage libraries: AsyncTCP library version 1.0.3

I can guarantee that using the latest libraries will fix that error. More information here: https://github.com/espressif/arduino-esp32/issues/1887
Let me know your results.
