Software requirements

Your application or sample must enable modem trace and AT commands.

If you are using the nRF9160 DK or Nordic Thingy:91™, you can Program device with one of the built-in sample apps or required modem firmware (or both).

Alternatively, for all other compatible devices (including custom boards), make sure that your application matches the following requirements:

• The modem firmware must be at least version 1.3.3.
• The application firmware must use nRF Connect SDK version v2.0.1 or higher. The latest version is recommended.

• The application must enable modem trace. You can do this by adding a dedicated snippet to your application's build configuration, as described in the nRF Connect SDK documentation. The SDK offers snippets for UART, RTT, and other use cases.

  Note

  In the current release of the Cellular Monitor app, the RTT interface is not supported for traces capture. You can only view RTT modem traces captured outside of the tool.

• Your application must also include one of the following components from the nRF Connect SDK:

  • Modem Shell

  • AT Host library

    • Enable the library using the Kconfig option CONFIG_AT_HOST_LIBRARY in the prj.conf file of your application. The library exposes the AT commands interface to the application and enables you to communicate with the modem using AT commands.

  • AT Shell
