If you are using your development kit (DK) for the first time, please visit our out-of-box experience here. This will walk you through the set up of getting your DK connected to nRF Cloud running the Asset Tracker application.
This guide is written for those who are looking to get started with the nRF9160 DK which serves as an evaluation platform for the nRF9160 SiP. The nRF9160 is a System-in-Package (SiP) providing a modem capable of LTE-M, NB-IoT, and GPS connectivity while integrating an ARM 64MHz Cortex-M33, 256k RAM, 1M Flash, ARM Cryptocell 310, PMIC, and a variety of peripherals in a compact 10x16x1.0mm package. Also featured on the DK is the multi-protocol, 2.4GHz nRF52840, allowing for LTE gateway applications with BLE, Zigbee, Thread, etc.
An overview of the board can be found in the picture below, marked for reference in the sections to follow.
The below steps were developed on a Windows 10 PC but the steps should be similar for macOS and Linux.
The Secure Boot sample application provides a reference implementation of a first-stage boot firmware. This firmware is required to set up the nRF9160 DK so that it can run user applications in the non-secure domain. This should be loaded prior to loading non-secure applications and is loaded onto the board out of box.
Documentation for this example can be found here.
Watch the LTE Link Monitor introduction video here. This gives an introduction to the tool and some of the useful commands. You may find overlap with the steps in the video and the steps below.
There is only support for NB-IoT in China which we will not be sampling until the end of March. Please look for an update then.

Currently, we are only sampling LTE-M to the public with plans to sample NB-IoT at the end of March.The latest timeline can be found here: devzone.nordicsemi.com/.../nrf9160-development-status
If you live in an area where LTE-M is not available, then this would make sense. You can check the deployment map here: https://www.gsma.com/iot/deployment-map/
If you live in an area where LTE-M is available, I would suggest to move closer to a window or go outside to see if that helps with locking on to a tower.
OK watching the linked video I'm one step further, now it is responding, and UART, Modem and UICC status is green, but the LTE indicator is blinking yellow now for half an hour. Any hints how to get more information what the rootcause could be
Hello, thank you for the tutorial. Till step 3 of "Using LTE Link Monitor" everything works fine. I can connect to the board and can see zephyr booting.
But after this, no AT command is accepted, I allways get Error: AT+CFUN? timed out. This timeout I get to every AT command I tried. Does someone has an idea whats wrong?
Are you having trouble activating the SIM card or trouble connecting to an LTE tower? Which SIM card are you using?
