Muchas gracias!

Me ha ayudado vuestro ejemplo para tener una web y comunicarme con la ESP32.

In reply to Rainer.

Use the latest ESP32 core and the latest versions of the libraries.
Can you tell me the board you’re selecting and the exact error you’re getting?

Did a new try with the send email. now with the correct libs it compiles fine.
but it crasches with DMA problem. which version of the libs end esp32 add on should iuse

YesI know, but I be frustrated more and more

I reinstalled 2.3.6 started, go thr latest ESP32 3.0.3 from Espressive.

Start on page ESP32CAB eBook207 and try to install the libraries. But I can no more find the the requested libs by ESPAsync as requested in the library Manager, did them find some days earlier, I leared lib versions etc. may be important for compile and successfull run a sketch, so it would be fine to note the version you worked with in the eBook

In reply to Rainer.

First, you need to know where you Arduino folder is.
Usually, it’s in Documents > Arduino
Inside, there’s a folder called Libraries.
there you can check the libraries folders.

Thank you for the answer.
I do not think so. As I normally work with Platforn IO, I did a fresh install of the latest 2.x Arduino IDE , to go trough the examplea on your ebook. As I do not have much knowledge on the Arduino IDE, can can you tell me how to delete the old libs. I think just uninstall will not delete them. physically

In reply to Rainer.

Hi.
Do you still have the old AsyncWebServer libraries installed?
Or their folders in the libraries folder?

like you tutorials since at least 6+ years, but onc again theydo not compile

followed your instruction to get the same libs.
