Exporting signal strength data

[lancebadoni]

I am wondering how collected signal strength data can be exported into, say, a csv file for later analysis.

I am using a RasPi 2 running Raspbian Jessie with Pixel. My purpose in collecting and storing strength data is to create a 3D heat map of Wi-Fi signal strength for 2.4GHz.

This has been requested earlier in #18. I still think wavemon is not the right tool for that.

A better alternative is to use iw from e.g. a bash script, which could extract the data points into a CSV or column-format file; and could be run via a cronjob.

Hi, I also need the ame thing. Does iw has all the same stats offered by wavemon?
I also see on this page, that we can extract output using grep and sed. However its not working for me. It says that the (-d) option is not a valid option.

The -d option has been removed over 2 years ago, in dc81d8f. It seems that the Raspberry Pi page used an older version of wavemon.
You can probably achieve the same, if not better, results using iw. Have you looked into this?
