RIOT Spectrum Scanner Application

About

This script can be used to plot the radio signal spectrum when a connected node is running the spectrum-scanner application application located in the parent directory. This node scans over the available radio channels performing CCA measurements and outputting the measured ED level via a serial port. This output is then parsed by the plot_rssi.py script included in this folder run on a host computer.

Dependencies

The plot_rssi.py script requires pyserial for the serial port access, and matplotlib and numpy for the plotting functionality.

Installing the dependencies:

Debian/Ubuntu

apt-get install python-serial python-matplotlib python-numpy

PIP

pip install pyserial matplotlib numpy

Usage

General usage:

1. Flash a RIOT node with the spectrum-scanner application from (https://github.com/RIOT-OS/applications/tree/master/spectrum-scanner)

2. Run the plot_rssi.py script

$ ./plot_rssi.py <tty> -b <baudrate>
