In ESP32 IDF side you can send serial to a specific pin:
https://docs.espressif.com/projects/esp ... /uart.html There are examples.
And I would receive in the RX pin on the esp8266 side.

I also find odd to mix both arduino-ESP32 and IDF but I know some projects do. Here there is a demo of parsing open weather that compiles in IDF and uses arduino “as a component”

Do not really fully understand what you are trying to do here. If the html downloaded in the browser contains references to all audio .wav files yes then they will trigger the requests and be loaded in the browser. But are you serving all this from the ESP32? Downloading the full audio is what most ...

I think that this is not what i am looking for... you sent me a link which is talking about touch screen panel library... while I am trying to include an external servo moto library into Vs code (IDF ESP...)…Etc. What I mean is that looking at any other example, mine was just a reference, you can g...

I don’t know if this will really help, but once when I had still no Logic analyzer around,I used this arduino-ESP32 project to sniff aptitude ESP32 acting as slave SPI

But I was reducing the speed of the master to 4 MHz.

Please read the Build documentation and try to understand the examples I referenced.

HDne I already replied to your post here:
viewtopic.php?f=13&t=22634#p81631

Did you read the Build documentation? Because there lies the problem.
It’s better to read the documentation and learn from another working examples before looking desperately for an answer.

Just my opinion, from the experience working with Frameworks: I would not modify an internal ESP-IDF library. Since the Framework will be updated and just does not make sense IMHO to use a custom IDF fork just because of a custom library. In my opinion is better to make your custom OTA component tha...

That's somehow the minimum initialization in ESP-IDF. I know the learning curve is hard to grasp at the beginning but it also offers much more configuration options.
In WiFi getting started there is a nice recompilation of examples.

Hello HDNe, In order to do that is very good idea to understand at least to some extent the Build system . And also how CMakeFiles works. For example in my epaper component you can see how is using the components: https://github.com/martinberlin/cale-idf In that version the components are in the rep...
