Hi.
Instead of changing:
mbedtls_md5_starts_ret(&_ctx);
mbedtls_md5_update_ret(&_ctx, data, len);
mbedtls_md5_finish_ret(&_ctx, _buf);
 
Do the following instead:
Instead of using the following in your platformio.ini file to include the library:
lib_deps = ESP Async WebServer
use the following instead:
lib_deps = https://github.com/me-no-dev/ESPAsyncWebServer.git
Save the platformio.ini file and compile and upload the code again to your board.
 
Let me know if this helps.
Regards,
Sara
 

 
Hi Sarah,  I went to the git client download website but it is not clear to me how to proceed from there.
Web searches for this error did not yield anything I could decipher as being a solution for me.
(I’m on Windows 10 ver 22H2)
Library Manager: Installing git+https://github.com/me-no-dev/ESPAsyncWebServer.git
UserSideException: Please install Git client from https://git-scm.com/downloads
* The terminal process “C:\Users\user\.platformio\penv\Scripts\platformio.exe ‘run’, ‘–target’, ‘buildfs’, ‘–environment’, ‘esp32doit-devkit-v1′” terminated with exit code: 1.
* Terminal will be reused by tasks, press any key to close it.

Later ……   I have followed this procedure.
https://www.howtogeek.com/832083/how-to-install-git-on-windows/
But the choices you have to make were not obvious to me but I have  snapshots along the way and it has installed.

It has resulted in a command prompt window with this text:

Re-launch PIO  and get this:

ANYHOW, & SOMEHOW, IT’S ALL WORKING !!!  The websocket method works as intended.
Tell me, why is it necessary to go through 4 processes to finally get the new code on-board the ESP32.?

While your there I have the next module 2.4 working fine with PWM but the slider on another device (running chrome) is NOT updating & visa versa.  So there is something wrong with the Websocket portion somehow.

Hi.
Here are the fixes: https://rntlab.com/question/web-server-with-slider-doesnt-update-the-connected-clients/
Unfortunately, I didn’t have the time to update this project yet.
I’ll test it and update it soon.
I’m sorry for the issue,
Regards,
Sara
