When I compile a project it compiles OK.
But if I add a header file
#include "driver/i2c.h"
I get - Unresolved inclusion.

If I add the header file in hello_world_main.c - it's OK.
But if I crate a new C file and add the header file in the new file - I get an error - Unresolved inclusion.

How can I fix the issue?

Well...If I add the new files to CMakeLists.txt it becomes visible to libraries. Seems like it fixes the problem.

Some of the includes is not visible any way
#include "bt.h"
#include "bta_api.h"
#include "esp_gap_ble_api.h"
#include "esp_gatts_api.h"
#include "esp_bt_defs.h"
#include "esp_bt_main.h"
not visible when I want to use BLE features.

Hi jenya7,

It is hard to say what is the source of this issue basing just on the list of header files.

Could you post the name of specific BLE example that has this issue?
Ideally please select from standard examples available with Eclipse plugin installation.

Thank you. This way it works.
I see a set(COMPONENT_ADD_INCLUDEDIRS ".") entrance in the CMakeLists.txt file. So I understand all paths can be added manually. What is the syntax to add directories?

Because if I choose a template - it compiles OK, but if I want to add another modules to my projects - I get the same unresolved inclusion problem.
