This code allows to plot on a map the power of the signal as receveid from a device conneted to LoRaWAN.

Two cloud servers are considered: TTN and Loriot

We are suppposing that the devices are LoPy with a Pytrack board.

ABP authentication is used. To this end, constants:

DEVADDR = '____'
NWKSKEY = '____'
APPSKEY = '____'

in file pytrack/trackit.py must be configured.

Executing:

python mapplot.py

two files are generated:

• rssival.csv that stores the RSSI values of all the messages received by the cloud server;
• datatoplot.js that contains the data to be plotted. This is done automatically loading in a browser either file webmapplot.html or webmapplot_norefresh.html

Before starting:

1. In file mapplot.py:

   • set the CLOUD_SERVER variable
   • then, accordingly to the cloud server used, fill in the other related variables below

2. In file webmapplot.html or webmapplot_norefresh.html:

   • set the variables home_lat and home_lng to the home center of the map
   • add your own Mapbox accessToken:
   • set refresh period at line: <meta http-equiv="refresh" content="5">

3. Before starting, delete or store somewhere else files: "datatoplot.js" and "rssival.csv". Not deleting these files while cause new points to be added to them.
