Getting started with cellular products

For getting started with the cellular products, you can refer to the Developing with nRF91 Series documentation, which guides through the features, getting started steps, and advanced usage of the boards. For a self-paced, hands-on course, enroll in DevAcademy’s Cellular IoT Fundamentals course, which describes the LTE-M and NB-IoT technologies and the software architecture of a cellular IoT application based on Nordic Semiconductor nRF91 Series devices.

The System mode section provides information about switching between LTE-M and NB-IoT.

Cellular IoT in nRF Connect SDK

The following sections explain the different applications, libraries, and samples that use the cellular IoT products.

Modem library

The nRF Connect SDK applications for the nRF91 Series devices that communicate with the nRF91 Series modem firmware must include the Modem library. The Modem library is released as an OS-independent binary library in the nrfxlib repository and it is integrated into nRF Connect SDK through an integration layer, nrf_modem_lib.

The Modem library integration layer fulfills the integration requirements of the Modem library in nRF Connect SDK. For more information on the integration, see Modem library integration layer.

Library support

The following nRF Connect SDK libraries are used for cellular IoT:

• Modem libraries

• Libraries for networking

• LwM2M carrier library

• Memfault library

Applications and samples

The following application uses the cellular IoT in nRF Connect SDK:

• Connectivity bridge

The following samples are used for the cellular IoT development in nRF Connect SDK:

• Cellular samples.

• Memfault sample.

• Networking samples - These samples use an nRF91 Series device over LTE or an nRF70 Series device over Wi-Fi® for communication and connection.

Integrations

The following integrations are available for cellular IoT in nRF Connect SDK:

• nRF Cloud - nRF Cloud is Nordic Semiconductor’s IoT cloud platform that allows you to remotely manage and update your IoT devices using Firmware Over-the-Air (FOTA).

• Memfault - A cloud-based web application with nRF Connect SDK compatibility that monitors devices and allows you to debug issues remotely through an LTE or Wi-Fi network.

• AVSystem - Software solution provider that provides a device management platform.

Power optimization

For optimizing the power consumption of your cellular application, you can use the Online Power Profiler (OPP) tool. See Power profiling cellular applications for more information.
