Postby Sports5115 » Tue May 28, 2024 10:32 pm

ESP32 WROOM32D
latest IDF docker image
in menuconfig I enabled

Bluetooth/host bluedroid/
Bluetooth/controller
Bluetooth/bluedroidoptions/ Enable BLE 4.2 features

CMake txt:
idf_component_register(SRCS “ble_wrp.c”
REQUIRES driver
PRIV_REQUIRES nvs_flash bt
INCLUDE_DIRS “include”)

Code: Select all

rm -R build 
idf.py build
still getting

Code: Select all

/project/main/ble_wrp.c:20:8: error: unknown type name 'esp_ble_scan_params_t'
   20 | static esp_ble_scan_params_t ble_scan_params = {
      |        ^~~~~~~~~~~~~~~~~~~~~
I think this is not activated
#if CONFIG_BT_BLE_42_FEATURES_SUPPORTED==0
#error "BLE 42 features are not enabled in menuconfig"
#endif

In the code have you included the required bt/ble header files?

in sdkconfig I have

Code: Select all

CONFIG_BT_BLE_42_FEATURES_SUPPORTED=y

Code: Select all

   esp_ble_scan_params_t;
is implemented in

Code: Select all

  components/bt/host/bluedroid/api/include/api/esp_gap_ble_api.h

and i have this in my C file:

Code: Select all

  #include "esp_gap_ble_api.h"
same way as instructed in doc
https://docs.espressif.com/projects/esp ... ?highlight

so I dont understand why it doesnt work.

Can you post your whole CMakeLists.txt file? That might help me understand whats going on.

it finds the header, includes it, but the header doesn't contain the expected type?

Code: Select all

idf_component_register(
  INCLUDE_DIRS
    "."

  SRCS
    "user_main.c"
    "dio.c"
    "ble_wrp.c"

  REQUIRES
    driver
    esp_common
    esp_driver_i2s
    freertos
    hal
    log
    bt
    nvs_flash
)
also attaching the generated sdkconfig

I think the problem is with the state of BLE_42_FEATURE_SUPPORT in the header file. You can try to override it by removing the if/endif in the header file and forcing it to define esp_ble_scan_params_t no matter what. Remember to change it back later though.

I had to manually add

Code: Select all

add_compile_definitions(BLE_42_FEATURE_SUPPORT)
into cmake file.
What a shitty system :(
