BLE_INIT: controller init failed error with ESP-IDF and Arduino component #432
Description
I am running into this crash as soon as I call NimBLEDevice::init("");
It is based on a clean project with Bluetooth and Bluetooth host NimBLE enabled.
Added the compile definition to the main CMakeLists.txt file:
# 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 3.16)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
# "Trim" the build. Include the minimal set of components, main, and anything it depends on.
idf_build_set_property(MINIMAL_BUILD ON)
project(NimBLE_GATT_Server)
add_compile_definitions(ARDUINO_ARCH_ESP32=1)
The main.cpp file is:
#include <Arduino.h>
#include <NimBLEDevice.h>
void setup() {
delay(2000);
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect
}
Serial.println("INIT");
NimBLEDevice::init("");
}
void loop() {
Serial.println("loop");
delay(1000);
}It does not crash if the setup() and loop() are not called but if "Autostart Arduino setup and loop on boot" is enabled it does.

One workaround I've found is adding this include at the start of the main.cpp

@moritz89 could you provide more information as to your environment setup? This header is already included through:
esp-nimble-cpp/src/NimBLEDevice.cpp
Line 56 in 6d5a9be

Here is a minimal example of the crash. Using VS Code and ESP-IDF. Hope it compiles and flashes on your side. Used an ESP32 WROOM dev kit

Thanks, I needed to update the idf version I was using to repro but I have resolved both of your issues in #434

Thanks for the quick turnaround
