I tried to delete my posting because I made a mistake and that’s why it didn’t work.
Unfortunately I can’t delete unreviewed posts.
Can you please do that?
I apologize for that.
It works fine now.
Thank you for your work.

Hi.
Try to downgrade the ESP32 boards version to 3.0.7.
Then, let me know if that fixes the issue.
Regards,
Sara

Hi,
Thanks for this great tutorial.
Unfortunately I get this error message when compiling:
…libraries/ESP_Async_WebServer/AsyncWebSocket.cpp.o:(.literal._ZN17AsyncWebLockGuardC5ERK12AsyncWebLockGuardC5ERK12AsyncWebLock[_ZN17AsyncWebLockGuardC5ERK12AsyncWebLock]+0x0): undefined reference to `pxCurrentTCB’

Greetings from Germany

In reply to Sara Santos. It's just a minor typographical, not logical, error. If you check the code in the scrolling section of the tutorial above and on the raw code page in function submitForm(), you'll see that "var" is missing where it should say "var direction;".

Hi Sarah and Rui, thanks again for another great tutorial. I used some of this code to implement radio buttons. I believe there is an error in your raw text file, s/b
var direction;
https://raw.githubusercontent.com/RuiSantosdotme/Random-Nerd-Tutorials/master/Projects/ESP32/ESP32_Stepper_Motor_Websocket/data/script.js

function submitForm(){
const rbs = document.querySelectorAll(‘input[name=”direction”]’);
direction;
….

Hello Sara,
I have a problem with ESPAsyncWebServer by Iacamera:

I get an Error with ESPAsyncWebServer 3.1.2 and also with 3.1.0 .
I tried Arduino IDE 1.8.19, 2.3.0, 2.3.2 and 2.3.3 on different PC’s.

Are you using the same ESPAsyncWebServer?
if not, how can I get another make?

Thank you for the tutorial!
I just have one question, my motor stops shortly after starting and only starts again when the set cycles are about to end. What could it be?

Regards
Marco

Hi.
It should work with any version.
But, for uploading the filesystem image, you need to use Arduino 1.8.x
