tetra-mess

This is a simple CLI tool to take measurements of signal strength and quality from a TETRA radio terminal through its peripheral equipment interface (PEI).

tetra-mess uses the proprietary AT command AT+GCLI? to query the TETRA terminal for measurements. The command is only supported by radios from Motorola. You can find some more infomation about the command in some forums and blogs (german):

• TETRA, nützliche Einstellungen
• TETRA Netzabdeckung messen
• Tetra PEI: Software-Kommunikation AT-Komm.
• Digitalfunk Tetra: Motorola PEI

Installation

You can install tetra-mess using the Go toolchain:

> go install github.com/ftl/tetra-mess@latest

Usage

tetra-mess can record the measurements into a CSV or JSON file:

> tetra-mess measurements.csv

If you do not specify a filename, the measurements will be printed to the console.

tetra-mess can also evaluate a track file and convert it into a KML or GPX file in order to visualize the measurements on a map:

> tetra-mess eval track measurements.csv --name "Today's test drive"

The default output format is KML, but you can use the GPX format with the flag --format gpx.
