Hi,
would like to add nRF7002DK to the Golioth and observe the data from the device!
So far I have wind10 running VC with the ncs and west including python3 installed. I can build the zypher ncs examples and flash them to the device. I have enabled the zypher logging. Indeed went true your training. So far all works, however, not sure how to continue and connect the device to the net, eventually Golioth and read eg. the blinking LED.
Would you please give me a short example to follow?
Best!
Hi mu234, nice to hear from you!
When you mention you are building the “zypher ncs examples” can you tell me where those examples are located?
The best working example we have for the nrf7002dk is the 01_IOT example that use use in our free Zephyr training (the next training is in 2 weeks if you’re interested). Here is the code repository for that example:
Hi Mike
Thanks, I am following this example: zephyr-training/01_IOT at main · golioth/zephyr-training · GitHub
used my current account and added the required PSK information… as suggested.
However, when building the 01_IOT example via .env I got the KConfig errors, wondering what is going ?

Hey @mu234 ,
It looks like the build system isn’t seeing the Golioth module, and it’s unaware of the Golioth-specific Kconfig symbols used in the training applications.
Are you able to build Golioth samples, or are you experiencing the same Kconfig warnings?
Hey Marko!
I am trying to install the 01_IoT training example, which is the Golioth example, right?
While I can successfully build the e.g. 02_helloworld.
02_helloworld sample in the Zephyr training isn’t using any Golioth specific code, it’s the Hello World sample that has been copied directly from the Zephyr tree.
The Golioth samples I was referencing can be found in /modules/lib/golioth/samples.
01_IOT sample from the Zephyr training is using Golioth specific code. The most likely scenario for this kind of errors is that you didn’t add Golioth Zephyr SDK to the Zephyr based project as a west module correctly.
Start from successfully building the golioth samples from the SDK and work your way up to the Zephyr training applications.
OK, thanks, downloaded the Golith-zephyr-sdk-main and saved it to the root dir.
Doing the west update within the dir. , hope this is the right way…
Trying to build:
PS C:\golioth-zephyr-sdk-main\samples> west build -b nrf7002dk_nrf5340_cpuapp
ERROR: source directory "." does not contain a CMakeLists.txt; is this really what you want to build? (Use -s SOURCE_DIR to specify the application source directory)
FATAL ERROR: refusing to proceed without --force due to above error
PS C:\golioth-zephyr-sdk-main\samples>
Error, it looks, like the board driver is missing, how can I add the nrf7002dk board to the Golioth SDK folder?
OK, added the boards … tried to build, but still errors… wondering what does this mean?
Thank you in advance for any comments, help?
Best.

We just updated our training to use Codespaces as an online development environment. I would suggest following all the steps on this page to see if you can get the application to compile and run on your device: https://training.golioth.io/docs/zephyr-training/helloworld/compile-hello-world
As to the exact problem you are facing in this thread. I think we need to see the entire output of the build process to know more.
I have some concerns about what codebase is being build. Can you also run this command and paste the output?
west config manifest.file
¸Hello mike
thanks for the Codspaces … it works, I guess, if the IoT example is run I should connect to the Golitoh? Anyway, did try it out, should I follow the instructions?

Re virtual environemnt I am not really sure when I have to use the (.venv), and when I have to use the e.g. PowerShell instead of basic command prompt.
Yeah, I am not really a “administrator” 
Had several issues with activating the venv…
Re west config manifest.file
Not sure where to “launch” it so went to the zephyr-training directory, anyway, nothing with regard to the output, hope this was expected ?

BTW I am not sure where to run with regard to the command line tool, etc.

Hello marko,
I would like to explore the Golioth´´’s samples, but I cannot find the /modules/lib/golioth/samples.
For example, could you be more specific, where exactly is this location ?
In general, I went back and tried to reinstall the Golioth training examples… however, check the readme in the root dir. and got stuck here:
Local set up
Do not clone this repo using git. Zephyr’s west meta tool should be used to
set up your local workspace.
Install the Python virtual environment (recommended)
… code-block:: console
cd ~
mkdir zephyr-training
python -m venv zephyr-training/.venv
source zephyr-training/.venv/bin/activate
pip install wheel west
For example, what is meant by source zephyr-training/.venv/bin/activate ?
Anyway, the if the pip install wheel west is used it returns that it is already installed …
However, according to the instructions given in the Readme, namely the Do not clone this repo using git. Zephyr's ``west`` meta tool should be used to set up your local workspace.
I have a feeling I have to reinstall the repo?
Best.
The instructions on the zephyr-trainiing repository are what you would use for a Linux computer. The steps for Windows will be very similar but the command syntax is a bit different. For instance, setting up a python virtual environment will be something like this:
# Install a python virtual environment
python -m venv zephyr-training\.venv
# Activate the virtual environment
:: cmd.exe
zephyr-training\.venv\Scripts\activate.bat
:: PowerShell
zephyr-training\.venv\Scripts\Activate.ps1
From there, follow the instructions on the zephyr-training repo README. When directories are references you’ll need to change the forward slashes (used in Linux) to backslashes (used by Windows).
Regarding the Golioth SDK samples: The zephyr-traininig repository is meant to be a standalone folder and will includes a deps folder that has both Zephyr and the Golioth Zephyr SDK in it. You should be able to find it in the zephyr-training\modules\lib\golioth folder. Just understand that those samples don’t have configuration and overlay files for the nRF7002. You’ll need to craft those and handle the WiFi connectivity yourself.
Thanks mike, these looks very useful, indeed, it works now,
the major problem was the fact that, I did not know that the training etc. is Linux syntax, my fault …
With regard to the "deps folder" I do not see it. For example. I have downloaded the zephyr-training-main which apparently does not have the mentioned folders? I have as well downloaded the golioth-zephyr-sdk-main and there is no folder named modules there as well.
With regard to the nRF7002dk Wi-Fi connectivity I guess the 01_IoT example could be used and connect to the Golioth, etc. ? I am intending to use the nRF7002DK for the PoC anyway …
Before I delve into the crafting, would you please comment:
Best.
