Hi.

If you can't find the solution to your problem here, I suggest that you create a new ticket with a detailed explanation of your problem. Include SDK version, HW etc.

Br,
Joakim

Hi,

I know this is an old post but I'm facing exactly the same problem.

I first tried to use the main.c file from the blinky example project in SES but I face the same error. I'm not able to even compile that program.

Did you ever manage to solve the problem?

Thank you

Ok, then it sounds like you've managed to get started.

I'll forward the feedback internally so that we can consider the suggestions for new tutorials in the future.

You are welcome to post a new ticket if you have further questions. My colleagues and I will do our best to help you.

Best regards

No, I'm not looking for a C programming course.

In the meantime I managed to figure out how libraries work in SES and I was able to include some additional libraries. I found the information here:

https://devzone.nordicsemi.com/f/nordic-q-a/30904/how-to-add-library-to-a-sdk-example-in-segger-embedded-studio

I looked at the .h files to find the functions that are available.
In this way I was able to merge several examples and make them work.

When I get an error that sdk_config.h is missing, I just create an empty file and it works fine. You are right, the file is included in some examples, but not all.

In short what I want to state is that it's pretty difficult to get started in SES. Compared with Arduino IDE, Arduino IDE is much easier.
I would also suggest to make a video about how to include libraries and how to make blinky from scratch.
What I'm also missing is some instruction videos attaching sensors/actuators to the nRF and make them work.

I understand.

I'm afraid that we don't have any beginner guides on C programming, if that is what you are looking for.
Most of the guides we have is about getting started with our nRF5 SDK and the development tools that we provide.

I really wouldn't suggest starting a fresh, blank project. It would require quite some work to include all the necessary files, libraries, pre-processor definitions and headers, especially if you don't have much prior experience with our SDK.

I suggest that you find the project that is closest to what you are trying to achieve for your project, and then add or remove functionality from that.
Otherwise we have the ble_app_template project which is a good template project to start out with.

[quote user=""]If I copy main.c from blinky to a blank project in SES, I get the following error[/quote]

This is to be expected. If you copy the main file to a blank project, the blank project won't have all the .c files, .h files, defines or settings that the project makes use of.
How to add files and libraries to your project is explained the Youtube-videos about SES that I linked to in my previous answer.

[quote user="ephimee"]I want to use Serial.println, digitalwrite, analogread, softwareserial, wire and flash.read[/quote]

I haven't worked much with Arduino, so I can't really say if this is examples or functions that you are referring to. I don't know any specifics about them so I can't say for sure what that could relate to in our SDK.

I suggest you take a look at the examples we have in our SDK to find what would match your requirements the best.

[quote user="ephimee"]I already watched all the educational videos. The only comment I have: the file sdk_config.h does not exist.[/quote]

The sdk_config.h file is included in most of the examples in the nRF5 SDK.
I.e. For the template example, you can find the sdk_config.h file in the following folder:
nRF5_SDK\examples\ble_peripheral\ble_app_template\pca10040\s132\config

Opening the SES project, the sdk_config.h file should be available in the application folder in the project explorer (ref. attached image below):

If you have further questions, please let me know.
Best regards,
Joakim

No, I don't want to use BLE Mesh.

I want to use Serial.println, digitalwrite, analogread, softwareserial, wire and flash.read

I already looked at devzone, infocenter and the official website. They do not provide the answers I seek.

I already watched all the educational videos. The only comment I have: the file sdk_config.h does not exist.

I don't understand what you mean with github repositories? I need to understand how to start my own project, not opening examples that just work and are missing extra libraries.

I understand.

If you are looking to learn how to use our SDK, BLE etc, I don't think starting with automating BLE Mesh Provisioning is the place to start.

Are you planning to work with BLE Mesh?

If you want more basic knowledge about BLE Mesh, I suggest that you take a look at the introduction videos the BT SIG provides on their website or maybe their own study guides. You will get some more information about the tech, terminology etc.
https://www.bluetooth.com/blog/an-intro-to-bluetooth-mesh-part1/

For more information about how to use the different development tools that we provide, you will be able to find that here on devzone, documentation in our infocenter and general information on our official website.

All the examples we provide can be found in our nRF5 SDK.
We also have Nordic Semiconductor's official GitHub account, which contains officially supported repositories.
For additional Nordic repos see https://github.com/NordicPlayground

We also have a youtube-channel with different educational videos.
Here we have a tutorial series about getting started with SES and the nRF5 SDK:

I think you misunderstood my question.
I already went through those links.

But let me guide you through my thinking process.

I start with the second link, Automating Nordic BLE Mesh Provisioning

The page suggests the use of python scripts???
I tried but I get:
python interactive_pyaci.py -d COM20 -l 3 < command.txt
python: can't open file 'interactive_pyaci.py': [Errno 2] No such file or directory

There's no information on the page regarding this script, no download link and no installation instructions.

Let's go for the first link, the tutorials
My first impression is, are these beginners tutorials? Because I don't understand any of them.
Also, in about every tutorial I read " It is expected that you have basic knowledge of how to use SES, keil, nRF connect etc".
So where can I find these tutorials about SES, keil, nRF connect?

How do I start a new project in SES?
How do I include the nrf_delay library?
Where do I find the examples blink, serial.println, digitalread, analogread, wire.begin, flash.read?
Can you tell me how a project is structured. What do the subdirectories mean like nRF_Drivers, nRF_Libraries, nRF_Log?
Where can I find a tutorial to teach me the basics in SES?

Hi.

We have quite a few tutorials, blog-posts etc. that can help you get started right here on DevZone:
https://devzone.nordicsemi.com/nordic/

I would suggest that you start by looking at the beginners tutorials on advertising, services and characteristics.
Those can be found here:
