ESP32 Forum

Hello,

I am developing an BLE Peripheral app with esp32c3 controller and nimble bluetooth stack.
I want to use Device Information Service with some of its characteristics.

These characteristics are enabled by setting the variables such as etc. By default these defines are NULL and The DIS is added without these characteristics.
I read in the nimble documentation that with a newt tool these variables can be set (https://mynewt.apache.org/latest/os/mod ... ynewt_val_)
But this is not possible when nimble is used with esp-idf build system(?)
can someone please tell me how can I define MYNEWT_VAL_* defines in application without modifying the esp-idf files (esp_nimble_cfg.h).

Thank you

The syscfg.yml and pkg.yml files that are part of mynewt-nimble system to set /unset a variable are not used "as is" in IDF. As of today, these are not used in IDF . Instead IDF either provides a way to configure few options via menuconfig and uses esp_nimble_cfg.h to have default definations of all the macros.

So, if a macro is defined in esp_nimble_cfg.h and you want to override its value by re-defining it in application, will not work as of today.
