Building and testing a sample
application
After testing a prebuilt application, you should build one of the sample applications provided by the nRF
Connect SDK.
The nRF Connect SDK provides several samples for the nRF9160 DK. See Samples and Applications for a list
of all available samples and applications.
The following sections guide you through installing the nRF Connect SDK, programming a sample
application, building and testing the basic nRF9160: AT Client sample, and building the nRF9160: Asset
Tracker v2 application from scratch.
4.1 Installing the nRF Connect SDK
The nRF Connect SDK includes the libraries and samples that you need to build an application. It also
contains the required development tools, including SEGGER Embedded Studio (SES) Nordic Edition. SES is
free to use with Nordic Semiconductor devices.
The recommended way to install the nRF Connect SDK is through an app in nRF Connect for Desktop.
nRF Connect for Desktop provides different apps to simplify installing the nRF Connect SDK, depending on
the operating system that you are using.
Note: If you prefer to install the nRF Connect SDK manually, see Installing the nRF Connect SDK
manually for instructions.
Complete the following steps to install the nRF Connect SDK using an nRF Connect for Desktop app:
1. Download and install nRF Connect for Desktop.
2. Install and run one of the following apps:
• On Windows, use the Toolchain manager. This app installs the full sandboxed toolchain that you
need, including SES Nordic Edition and the nRF Connect SDK source code.
• On Linux or macOS, use the Getting Started Assistant. This app assists you in setting up the
toolchain, the nRF Connect SDK source code, and SES Nordic Edition.
See nRF Connect for Desktop for information about how to install and open apps.
3. Follow the instructions in the app to install the nRF Connect SDK.
4. Make sure that you have the correct version of the nRF Connect SDK source code. Unless instructed
otherwise, you should work with the last tagged release of the nRF Connect SDK.
• If you used the Toolchain manager app, you installed a specific version and no further action is
required.
• If you used the Getting Started Assistant app, make sure that you checked out the correct version
and ran west update.
If you want to switch to a different tagged release or to the latest version on the main branch, see
Updating the repositories for instructions.
