How to combine ESP32-Rainmaker and ESP32-ADF? (MEGH-1759)

[daluge]

ESP32-ADF use idf version v3.3.2, but ESP32-Rainmaker usb idf version v4.xx.
I checkout higher version of idf for ESP32-ADF, it compile fail. Then I also checkout lower version(v3.3.2) for ESP32-Rainmaker, it compile fail too. My project may need to play mp3 or tone except interaction through amazon alexa using ESP32-Rainmaker.

@daluge , can you please refer to this issue in esp-adf and see if it helps?

@shahpiyushv thx. I rewrite CMakeLists.txt in esp-adf directory that use the same idf as esp-rainmaker use, and now it succeed to compile for a project in esp-adf. However, i still bother how to use a project in esp-adf as main project, and use esp-rainmaker as component? I tryed to rewrite CMakeList.txt in project "play_mp3", but when i invoke function in esp_rainmaker, then it failed to compile.

Error info like: /home/xxx/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: /home/xxx/esp/project-adf/esp-rainmaker/examples/test_desktop/main/app_main.c:79: undefined reference to `esp_rmaker_device_add_param'

My project directory as follows: project-adf: ---> esp-rainmaker ---> play_mp3

I have succeed to compile and run the project with adf and rainmaker. let me do more test and functions ...

1. sdk change: perpare esp-adf with the latest version. perpare esp-rainmaker with the latest version. perpare esp-idf, change its version to v4.1. modify file "esp-adf/CMakeLists.txt", change IDF_PATH -> set(ENV{IDF_PATH} "$ENV{esp-idf}/") cuz esp-adf has its own esp-idf which version is v3.3.2, and for convinence to use 2 sdk, here i use esp-idf outside.

2. check example project: check an example in esp-adf can compile and work, check an example in esp-rainmaker...

3. create test project: then new a directory 'project-esp-rainmaker' in the same directory of 'esp-adf' and 'esp-idf', copy the example project like 'pipeline_http_mp3' in esp-adf to directory 'project-esp-rainmaker', copy the whole directory 'esp-rainmaker' to directory 'project-esp-rainmaker/pipeline_http_mp3',

4. dependent (project) change: change file 'project-esp-rainmaker/pipeline_http_mp3/CMakeLists.txt', add code after 'include($ENV{ADF_PATH}/CMakeLists.txt)' set(EXTRA_COMPONENT_DIRS $ENV{ADF_PATH}/components $ENV{ADF_PATH}/../project-esp-rainmaker/pipeline_http_mp3/esp-rainmaker/components $ENV{ADF_PATH}/../project-esp-rainmaker/pipeline_http_mp3/esp-rainmaker/examples/common )

5. dependent (content) change: change file 'project-esp-rainmaker/pipeline_http_mp3/main/CMakeLists.txt', add .c and .h from 'pipeline_http_mp3/esp-rainmaker'.

6. component change: change file 'project-esp-rainmaker/pipeline_http_mp3/main/component.mk', if xx.mp3 used.

7. menuconfig setup: -1- Partition Talbe ---> Custom partition table CSV copy partitions.csv in 'project-rainmaker\pipeline_http_mp3\esp-rainmaker\examples\switch' to 'project-esp-rainmaker/pipeline_http_mp3'

8. project change: -1- use one net config: use net config of esp-rainmaker, delete net config code of esp-adf if used. -2- use one storage: use storage if esp-rainmaker. -3- peripheral and io: comment code about app_driver.c of esp-rainmaker, comment code about audio_board_key_init() of esp-adf. only use either or write by myself.

project directory: --> esp-adf --> esp-idf --> project-rainmaker --> pipeline_http_mp3 --> components --> esp-rainmaker --> main
