Description

I try to compile a project for the ESP32-C3 by using esp-idf 4.4.1 in PlatformIO and the Arduino Core as a component. The linking failes, because of this error:

c:/users/konta/.platformio/packages/toolchain-riscv32-esp/bin/../lib/gcc/riscv32-esp-elf/8.4.0/../../../../riscv32-esp-elf/bin/ld.exe: .pio\build\debug\esp-idf\arduino-esp32\libarduino-esp32.a(BLEAdvertising.o): in function `BLEAdvertising::start()':

Compiling for the ESP32 Dev-board works without an issue.

@Kampi

I tested the BLE_server.ino example that uses this same API and I compiled it using the Arduino IDE with no errors.

I think it may be a problem of PlatformIO configuration from your side.
Please test your Project using the Arduino IDE if necessary.

If the problem persists, maybe you can open an issue within PlatformIO github.

CONFIG_BT_BLE_42_FEATURES_SUPPORTED=y was not set in sdkconfig.

@valeros - Is this something that should be configured in the PIO side?
Please let me know.

Hi @SuGlider, everything is fine. It was a mixed IDF/Arduino project that required a special option in the sdkconfig.

I also face this problem today. It only needs to tick CONFIG_BT_BLE_42_FEATURES_SUPPORTED=y in menuconfig

But it is not tick by default. And some document like this https://github.com/nkolban/esp32-snippets/blob/master/Documentation/BLE%20C%2B%2B%20Guide.pdf not mention this.

Could we add this to this document? https://docs.espressif.com/projects/arduino-esp32/en/latest/esp-idf_component.html

Thanks for the reminder.
