random question about the new esp idf in platformio? library, component, or include?

[wegunterjr]

I have this in my lib folder right now and have been using it that way for a while... PLatformio added the cmake build tools to allow the esp idf to be built more like normal, but now I am not sure what do with the snippets... are y'all including it as a lib or in the component folder, or are you putting it in the include folder?
Either way, what are your working ways to use the cmakelists.txt?

Hi, this library is more or less prepared to be used with cmake, but not sure how it will behave with platformio and cmake they build. I put a lot time and effort to help with this library, but recently @h2zero started to porting nimble to arduino library with almost 100% compatible library. Its worth to mention, because nimble is ble only and this will make it more portable in heap and flash usage. Really worth to try.

ah..because in arduino there is so much issue with the memory size of the libraries and not able to run BLE and WiFi at the same time? I can do it with esp-idf, but couldn't with Arduino when I first started this journey...

Thanks for the mention @chegewara 😃.

@wegunterjr Yes NimBLE is a significant improvement in resource usage. If you are using IDF 3.3+ and would like to try it I would suggest using the IDF version of the library https://github.com/h2zero/esp-nimble-cpp. NimBLE-Arduino isn't really meant for IDF use right now, since IDF has NimBLE already it just needs the cpp wrapper in project/components.

Thanks for that. I am updating to IDF 4 at this time, so working through those changes now. I was able to get it included by adding this to my CMakeLists at the top level:

set(EXTRA_COMPONENT_DIRS "components/cpp_utils")

and then in the cpp_utils folder, I added this:

# Edit following two lines to set component requirements (see docs)
set(COMPONENT_REQUIRES
  "console"
  "fatfs"
  "json"
  "mdns"
  "nvs_flash"
)
set(COMPONENT_PRIV_REQUIRES )

file(GLOB COMPONENT_SRCS
  LIST_DIRECTORIES false
  "*.h"
  "*.cpp"
  "*.c"
  "*.S"
)
set(COMPONENT_ADD_INCLUDEDIRS ".")

register_component()

My question now, is, if I have a 2nd Library next to cpp_utils in the components folder, how does it know about cpp_utils. I tried adding it in the COMPONENT_REQUIRES , but that doesn't seem to work...

thoughts?

It should works, but i would suggest to ask this question on forum. Angus will answer it best.
