Cellular Monitor supports Nordic Semiconductor Development Kit (DK)s
and prototyping platforms. Your application or sample must enable modem trace and
AT commands.
Minimum requirements
- nRF91 Series DK with a USB cable, a Nordic Thingy:91™, or a custom board with an nRF91 Series System in Package (SiP)
Either Program one of the built-in sample apps and/or required modem
firmware, or both, or enable the following on your device:
- 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 over Universal Asynchronous Receiver/Transmitter (UART) using
snippets. See nRF Connect SDK nRF91 modem tracing with UART backend using snippets for more
information.
- Your application must also include Modem Shell, the AT Host library, or AT Shell. See the following
for more information.
- Enable the AT Host 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.
- Information on Modem Shell and AT Shell can be found in nRF Connect SDK documentation
Limitations
Some limitations apply for applications that do not use AT commands extensively.
In the first release of Cellular Monitor, the
information in the Dashboard tab and the Connection
Status is based on the AT commands in the modem trace. This limits trace
data for applications that do not extensively use AT. It is recommended to use the option
Open in Wireshark where you can find all available
traffic.
