Feedback

[raphael-bmec-co]

Hello.

Firstly, thank you for this amazing tool.

Secondly, I have just worked my way through getting this working and I would like to add a little feedback that will make the instructions easier for someone who is potentially inexperienced to follow:

1. I think it would be worth explaining that the CMakeLists.txt from the respective examples should be moved to the root.
2. I'm using CLion and I needed to add the following to the CMake options (the second -D was critical)

-D CMAKE_TOOLCHAIN_FILE=Arduino-toolchain.cmake -D SERIAL_PORT=COM9

Hey, Thanks for your feedback.

For 2, I understand your problem. You are actually using some "undocumented" feature to set the default value of the serial port when invoking the CMake. You can also use the documented way of passing the serial port as environment variable in CLion. However, CLion or other IDE specific usage documentation is lacking and expected to improve in the future. I suggest you continue using the method you discovered. Note that in release 1.1 of the toolchain, the name changed to ARDUINO_UPLOAD_SERIAL_PORT.

For 1, I did not understand your problem. As far as I know, there is no need to move CMakeLists.txt anywhere. Just need to point to the appropriate directory as the CMake source directory (i.e. Use Examples as CMake source directory to build all examples, or use Examples/01_hello_world to build only the hello world example.)

Hey, thanks for getting back to me so quickly.

I was running off master. I have just moved to release 1.1 and I am not having "issue" 1 anymore. I suspect this has more to do with something I changed on my side than the version change.

For the sake of helping anyone who tries to set this up on CLion in the future. The "tricks" for setting up a working project are as follows:

1. Extract the "Arduino-CMake-Toolchain-release-1.1-dev" to wherever you would like to keep the toolchain.
2. Create a folder for your project and copy the example of your choice (for example CMakeLists.txt hello_world.cpp).
3. Open CLion, and open the project folder. It will automatically load the CMake project and fail.
4. In the File -> Settings -> Build, Execution, Development -> CMake dialog set the CMake options to -D CMAKE_TOOLCHAIN_FILE=path/to/Arduino-toolchain.cmake -D ARDUINO_UPLOAD_SERIAL_PORT=COM9 (Check the actual port for your device).
5. Click OK. The build will fail as per the documentation to allow selection of the board.
6. Build again and upload as per the documentation.

The most important point is that you should not open the root "Arduino-CMake-Toolchain-release-1.1-dev" in CLion as it will create additional CMakeLists.txt files that will cause issues.

UPDATE

This issues is related to #19

Hi. Next challenge:

I am struggling to include BLE libraries. Interestingly this is one library with several includes. Maybe that is related to the issue?

I have tried replacing BLEDevice with the library name ESP32 BLE Arduino.
I have tried the other includes: BLEUtils and BLEServer.

I have also tried AUTO_PUBLIC, AUTO_PRIVATE, PUBLIC and PRIVATE.

I have verified that the includes are located here:
C:\Users\Raph\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\BLE\src.

The error mentions the search path: C:/Users/Raph/AppData/Local/Arduino15/packages/esp32/hardware/esp32/1.0.4.

I am going to keep at it, maybe I am missing something but your help would be great.

Thanks

I have marked this issue as enhancement to make the upload, ISP and other tool related options (like SERIAL_PORT) available through board options file, to improve the usage experience.

EDIT

Found the issues in the CMakeLists.txt:

add_executable(arc003-2 arc003-2.cpp)
needed to be
add_executable(arc003-2 arc003-2.cpp modules/ble/services/wifi/ble_wifi_services.cpp)

---

Thank you, that would be a nice enhancement.

I have another question. Again, not sure if I am doing something wrong.

I am building a large project and I have a .h and .cpp file in some nested folder:
modules/ble/services/wifi/ble_wifi_services.h
modules/ble/services/wifi/ble_wifi_services.cpp

CMake runs fine but when compiling I get:

Questions:

1. In my main app, should I include ble_wifi_services.h as:
   #include "modules/ble/services/wifi/ble_wifi_services.h"
   OR
   #include "ble_wifi_services.h" (when I do it this way the IDE does not find the h file but I'm concerned this is becuase it isn't linking).
2. Is the CMakeLists.txt below correct?

cmake_minimum_required(VERSION 3.0.0)
