Get started with the nRF91 AT Host Application

This guide takes you from an nRF54LM20B DK and an nRF9151 DK to a device that reports its location to nRF Cloud. The application runs on the nRF54LM20B DK and drives the nRF9151 DK, which runs the Serial Modem firmware, with AT commands. The Serial Modem onboards itself to nRF Cloud and does all cloud communication, so there are no certificates to install on the host.

This guide covers steps 3 to 6: Set up the hardware, Build and flash, Connect to nRF Cloud, and Verify

Before you start, complete Step 1: Choose your application. To build from source, also complete Step 2: Set up the repository and toolchain.
