Previously we were using Kiel with another Nordic Product. It worked perfectly, was easy to install and it worked. What do we need to do to use Kiel again.

Doesn't seem like the screenshot was uploaded here. To upload an image or a file, try the following:

Then press Upload file here, and navigate to the image you want to upload.

But if you see the same as me and build the same way, then the errors you're seeing most likely point to something having gone wrong during installation of the SDK or VS Code extension. If that's the case, uninstalling and reinstalling the VS Code extension, VS Code as a whole and the nRF Connect SDK, as it seems like CMake and Python dependencies haven't been installed correctly.

Best regards,

Hello,

I am using the nRF54L15 Development Kit

I think I am using the VS Code extension as I can see the same screen as per the image you have attached with the same parameters.

I have saved a screen grab as a file and all parameters are the same as per your image. I have tried to attached the image file, however I can not attach the file to this message. I have tried Insert\image/video/file\File/URL I enter the complete path C:\Users\Brian\OneDrive\Desktop\IMAGES followed by the full file name and nothing can be uploaded.

Cheers,

Brian Fleming

Hi Brian

Are you using the VS Code extension to build the project? What board are you building the application for here? Start with the nRF54L15 DK and upload the full build log here. if you see the same issue. Also, make sure you have the same version of the nRF Connect SDK as the toolchain when you build.

Here's how the build page should look if you're building the project with the VS Code extension:

Best regards,

Simon

Hello,

I seem to have resolved the python issue although I do not know how.

[cmake] -- Found Python3: C:/Users/Brian/AppData/Local/Programs/Python/Python313/python.exe (found suitable version "3.13.2", minimum required is "3.10") found

However, here is the next issue.

[cmake] CMake Error at C:/ncs/v3.1.1/zephyr/cmake/modules/extensions.cmake:3511 (message):

[cmake] BOARD is not being defined on the CMake command-line, in the environment or

[cmake] by the app.

I have tried everything within the Visual Studio environment that I could think of and have done many searches on the web but I have not found anything which makes sense for me.

Sorry for my lengthy delay in replying, but I have many other work responsibilities.

Cheers.

I assume you had Python already installed when installing the nRF Connect SDK and VS Code extension, correct?

On Windows, this usually fails when another Python on your PATH interferes, or when the toolchain’s Python is not visible. Nordic recommends ensuring that the toolchain’s Python is the one CMake picks up.[Build fail CLI][VS Code Python env]

The first thing to try is that if you haven't, close all VS Code tabs in order to refresh/update all instances of it on your computer, then reopen it again. Next make sure you open the SDK folder so you have the workspace/environment set up correctly. I usually open up the folder of NCS I'm using (C:\ncs\v3.2.0). Then, go to the nRF Connect VS Code extension tab and "Manage SDKs" and "Manage Toolchains" to make sure you have the correct SDK and toolchains try building the project you want. Please let me know if you still see the same error messages.

Best regards,

Simon

Hello. could you take a look at the attached notepad file.

I have documented as well as I can about my inability to compile due to a Python error.

Cheers,

Brian Fleming

My problem is that I can not compile (Build) a program like I could with Kiel because it says there is a problem with missing Python.

I have selected the peripheral_uart from the SDK as it seems that

static void bt_receive_cb (struct bt_conn *conn, const uint8_t *const data, uint16_t len)

has the functionality the I require.

I open the peripheral_uart in the VS Code development environment and without any changes to the code if I click the Build button to compile I receive the following in OUTPUT

And the following in PROBLEMS

Obviously, it is not finding Python which is installed on my machine. The where and version are returning the following values.

C:\>where python

C:\Users\Brian\AppData\Local\Microsoft\WindowsApps\python.exe

C:\>python --version

Python 3.13.9

In the VS Code environment if I click the Gear (Manage) and select the Settings options and search for pyth I find a field which I enter as per below.

C:\Users\Brian\AppData\Local\Microsoft\WindowsApps\pythonw3.13.exe

In the VS Code environment in the Extensions the nRF Connect for VS Code and the nRF Connect for VS Code Extension Pack are both installed.

I have watched the nRF Connect for VS Code, part 1: Installation video in the internet and it does not say anything about configuring Python.

If you're new to the nRF Connect SDK I would strongly recommend checking out the DevAcademy course on nRF Connect SDK fundamentals: https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/.

And to answer your question, we do have an equivalent of the BLE NUS example in the nRF Connect SDK as well. It is found under Samples/Bluetooth/peripheral_uart here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/peripheral_uart/README.html This already implements the NUS service and should work out of the box on the nRF54L15.

static void bt_receive_cb (struct bt_conn *conn, const uint8_t *const data, uint16_t len)

memcpy(tx->data, &data[pos], tx->len); I think data[] holds the characters received from the central.

RE: Example code

DESMODUCATI2 — Thu, 04 Dec 2025 06:58:17 GMT

I am thinking now that 'bluetooth le uart services' might be where I should be looking, specifically, the routine 'bt_receive_cb' . Any assistance would be appreciated.
