Trying to incorperate my own sensor script into the BLE Mesh sensor server example. Can't build from my project folder OR the idf example folder. (IDFGH-4301)

[mrSilkie]

I have IDF v4.1 installed

# get_idf
# cd ~/esp/esp-idf/examples/bluetooth/esp_ble_mesh/ble_mesh_sensor_model/sensor_server
# idf.py build

results in many familiar lines...

Any help will be much appreciated!:+1:

I am also trying to incorporate the mesh example into a folder in my own directory so any pointers to what changes i need to make to my CMakeLists is appreciated. I have already tried the following

>idf_component_register(SRCS "smartbucket.c"
                    INCLUDE_DIRS "~/esp/esp-idf/components/bt/esp_ble_mesh/api/models/include"
                    INCLUDE_DIRS "~/esp/esp-idf/components/bt/esp_ble_mesh/api/")

with no success

Hi @mrSilkie

The ble_mesh_example_init.h is included in the common_components. When trying to include the header file, the extra component needs to be added into the CMakeLists.txt or Makefile.

Like this: https://github.com/espressif/esp-idf/blob/178b122c145c19e94ac896197a3a4a9d379cd618/examples/bluetooth/esp_ble_mesh/ble_mesh_sensor_model/sensor_server/CMakeLists.txt#L5

@chegewara Thanks for the update.

Thanks.

@chegewara Thanks for the update.

Thanks.

Great reply. I'm still a bit stuck. My CMakeLists.txt looks like;

# The following lines of boilerplate have to be in your project's
# CMakeLists in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.5)
set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/bluetooth/esp_ble_mesh/common_components/example_init
    EXTRA_COMPONENT_DIRS ~/esp/esp-idf-lib/components/
    EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/components/bt/esp_ble_mesh/api
    EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/bluetooth/esp_ble_mesh/common_components/example_init)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(smartbucket)

Which fixed the ble_mesh_example_init.h not found error but the following line produces a second BLE related error.

../main/smartbucket.c:27:10: fatal error: esp_ble_mesh_defs.h: No such file or directory
 #include "esp_ble_mesh_defs.h"
          ^~~~~~~~~~~~~~~~~~~~~

I really appreciate your first reply but I feel like I'm still a bit useless here. How am i meant to know to include /common_components/example_init to resolve ble_mesh_example_init.h?

I am asking as I now want to resolve esp_ble_mesh_defs.h and have already included EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/components/bt/esp_ble_mesh/api

Please list the structure of project.

And, try to add private requirements components. Reference.
