So did you write your project for ESP-IDF v3 or v4?

If you want to compile for the last v3 version just add a platform_packages instruction to use that version.

platform_packages =
    framework-espidf @ 3.30300.190916

(referenced from Service End for Bintray, JCenter, GoCenter, and ChartCenter | JFrog)

I try port to v.4, but when i add

platform_packages =

framework-espidf @ 3.30300.190916

Huh interesting, if it worked before then the backwards compatiblity isn’t working when trying to build ESP-IDFv3 projectes. (cc @valeros).

I think you can get atleast the project to compile in its old form when deleting the platform_packages line from the platformio.ini and instead modfying the platform to say

platform = espressif32@1.11.2

But that doesn’t help you when porting over the project to v4 of course.

Do you have the full platformio.ini and code for reproduction?

I will stay with the old version.
Thank you for your help.

platform = espressif32@1.11.2

is the right solution if you’re not ready to port your project to the new project configuration using CMake.
