Step 1: Choose your application

1. Make sure you have the following before you start, so you do not get stuck halfway:

   • A SIM card with a data plan.
   • An nRF Cloud account.
   • A serial terminal, such as the Serial Terminal app in nRF Connect for Desktop, PuTTY, Tera Term, or minicom.
   • nRF Util with the device command, which flashes the DKs. After installing nRF Util, run nrfutil install device.
   • For the PPP Host Application, Python 3 with pip, which installs the nRF Cloud command-line tools in step 5.

2. Find your hardware in the following table and note the guide for your application. You follow that guide from step 3.

   Your hardware	Application	Guide
   nRF54L15 DK or nRF54LM20B DK, wired to an nRF9151 DK	PPP Host Application	Get started with PPP on an nRF54 DK
   nRF93M1 DK	PPP Host Application	Get started with PPP on the nRF93M1 DK
   nRF93M1 DK	nRF93M1 AT Host Application	Get started with nRF93M1 AT
   nRF54LM20B DK, wired to an nRF9151 DK	nRF91 AT Host Application	Get started with nRF91 AT

3. Choose how you get the firmware:

   • Build from source: You build the firmware yourself and can change it. Continue to Step 2: Set up the repository and toolchain.
   • Flash pre-built firmware: You flash firmware from the latest release to evaluate the application. Skip step 2 and go straight to step 3 in your application guide. In step 4, follow the pre-built firmware option. See Release artifacts for what each release zip contains.
