Testing a prebuilt application
Before you start developing, program and run a precompiled application on your DK to ensure that the kit
functions as expected and the communication between your computer, the DK, and the cloud works.
If you want to see a demonstration of these first steps, watch the videos on nRF9160 DK Get started.
These videos cover the contents of this chapter.
3.1 Installing the required software
To be able to update the nRF9160 DK firmware and certificates, you must install several apps for nRF
Connect for Desktop.
nRF Connect for Desktop is a cross-platform framework for development applications. It contains apps for
programming firmware, monitoring LTE links, power optimization, and more.
You can download nRF Connect for Desktop from our website.
Note: On macOS and Linux, you must download and install the SEGGER J-Link Software separately.
You can install nRF Command Line Tools, which includes SEGGER J-Link Software.
After installing and starting the main application, you see an overview of available apps. Click the arrow
down button to display additional information about each app.
You must install the following apps:
• Programmer
• LTE Link Monitor
To install the app:
1. Open nRF Connect for Desktop.
2. Find the app in the list of apps and click Install.
Once the app is installed, you can launch it by clicking Open.
For easy access, you can create a desktop shortcut by clicking the arrow down button and selecting Create
shortcut.
If a new version of the app becomes available, an Update button is displayed next to the Open button.
Click this button to install the latest version. To uninstall the app, click the arrow down button and select
Uninstall.
If you plan to build your own application, you must install the nRF Connect SDK in addition. This
installation requires big downloads, which can take some time. Therefore, you might want to start the
installation while you continue with the initial test. See Installing the nRF Connect SDK on page 14 for
instructions.
