ESP-IDF 4.0 and Arduino

[jeremypoulter]

It looks like ESP-IDF does not (will not?) support building with Arduino as a component. Is it possible to configure the IDF version? or are we stuck at using version 1.11.2?

If not would it be possible to do a 1.11.3 release with the backtrack decoding?

Hi @jeremypoulter ! There is an example with ESP-IDF v4 and Arduino as a component (although a special branch of Arduino framework is used). Is there something wrong with it?

[jeremypoulter]

Silly me, only looked at my existing project, didn't see any reference to Arduino in the generated sdkconfig and the referenced issue looked to back that up. I will indeed try the example, but certainly it doesn't just work on existing projects :(

Hello,

i want to use IDF v4 and Arduino as a componant. I have tried several times the Arduino wifi scan example with the special branch of Arduino framework (just import project example).
I use vscode on windows 10.
At the first time the compilation is OK.

After I run menuconfig to disable Arduino autostart, then PlatformIO make some updates (and download the special branch in framework-arduinoespressif32@src-c69fc9322995db5694e2741d307d9723) and after I have compilations error with :

fatal: not a git repository (or any of the parent directories): .git CMake Error at C:/Users/edoua/.platformio/packages/framework-espidf/tools/cmake/component.cmake:171 (add_library): The target name "___idf_framework-arduinoespressif32@src-c69fc9322995db5694e2741d307d9723" is reserved or not valid for certain CMake features, such as generator expressions, and may result in undefined behavior.

If I do a clean install it's ok again, work a little on it and then the same error reappears.

I can confirm I got the same problem, I'm trying to compile with the
framework = arduino espidf
as set in the examples with no success.
