Missing "uart.h" library

Digisol

Hello!
I purchased a SparkFun Thing Plus - nRF9160 a week ago, successfully compiled and ran the accelerometer, and created a “hello word” from scratch.

However, when I try to compile “simple_at”, “at_client”, or any other project, multiple rows in prj.conf fail.

My biggest issue so far is that I can’t find a “uart.h” library to compile any of the projects. I searched the C:\ncs folder for “uart.h” files; there are about 40 uart.h libraries, I tried every “uart.h” library, but they all failed to compile.

I would like to make a HTTP Post project

Any help would be much appreciated!

Digisol However, when I try to compile “simple_at”, “at_client”, or any other project, multiple rows in prj.conf fail.

I’ll need more details. Can you share a log?

I recommend checking this sample: https://github.com/circuitdojo/nrf9160-feather-examples-and-drivers/tree/v2.4.x/samples/https

Make sure you’re using the latest version of NFED (currently 2.4.x as of this writing)

Digisol

Thank you for your prompt response.
I got the files from the Github link you supplied.
I unpacked and compiled the “at_client” project.

Compilation result is inserted as a code, I don’t know if I can attach a file, sorry about that.

I have Windows 10 Pro and the following software:
*- “nRF Connect 4.3.0”
*- Toolchain 1.3.0
*- West version: v1.1.0.

Sorry, I don’t know what NFED stands for.

Looks like your using Nordic’s Tooling? You likely need to look at their documentation/use their VSCode extension. The way that applications and the structure of Zephyr works it’s very particular on how things are placed. Thus why you’re getting errors about files being missing.

Otherwise you’re best, supported, path forward is following the docs here: https://docs.circuitdojo.com/nrf9160-sdk-setup-windows.html

Digisol

jaredwolff Merry Christmas!
Thank you so much for your assistance! It worked perfectly.

How can I close a compiled and programmed project in order to open another example project or start from scratch?

I chose “Close folder” the last time and had to restart with “Zephyr Tools: Init Repo” again.

Any suggestions are much welcomed.

I currently tried to build “ncs/v2.5.0/nrf/samples/cellular/at_client ((v2.5.0))” using the toolchain installation of the nRF Connect for Desktop 4.3.0, Toolchain Manager 1.3.0, running on Windows 11.

“Works on my machine”.

Simply open the project root folder (the one that contains NFED or whatever application you have) using the open folder command in VSCode. Projects retain their configuration/setup even id you “close out”.

Hope that helps!
