Problem building for ESP-IDF. about microocpp

[matth-x]

Hi @KasperHauge2,

The Mongoose integration supports both MG v7.8 and v6.14. For new projects I would recommend using the newer version of course. Then the build flag MO_MG_VERSION_614 should not be set.

In case you've already tried this, can you post the compiler error? I must admit that the build check for the esp-idf doesn't work perfectly yet and the head commits of the main / master branch could indeed be incompatible with each other. In any case, the newest commit from MicroOcpp, cesanta/mongoose-esp-idf and ArduinoJson should work with MicroOcppMongoose at commit 92ebea9fe85.

Apart from the dependencies as specified in the CI step for the esp-idf or the example folder structure, there are no further components to install.

I also realized that ArduinoJson just released v7 which is now the default branch. For MicroOcpp it's necessary now to checkout the latest v6 branch.

Thanks Matth.
When running the example code, and change the ArduinoJson to v6.21.5 and the MicroOcppMongoose to v1.0.0, then I can build it, and I think it works !

@KasperHauge2,

Thank you for bringing this issue up. It's necessary to pin the ArduinoJson version to 6 now and I changed the docs accordingly.
