Scan for wi-fi access points (Networks)

options:
  -h, --help            show this help message and exit
  -i <iface>, --interface <iface>
                        (Linux only) Interface to use, default=wlan0
  -r, --rescan          (Windows only) force network rescan for APs
  -j, --json            Output json result
  -c, --csv             Output csv result
  -v, --verbose         Debug/verbose output to console
  --nmcli               Force Linux Network Manager discovery
  --iwlist              Force Linux iwlist discovery
  --iw                  Force Linux iw discover
  --netsh               Force Windows netsh discovery

This utility will scan for network APs (Access Points) using underlying OS utilities
and list related information.

- Supports Linux and Windows.
- Output options include: formatted (default), csv and json

Examples:

Windows - trigger re-scan to get most current list of access points

> dt_apscanner -r

Notes:

• On windows, you can rescan (-r) and search for current networks
• You may save the outut of the underlying command into a file (-s)
• You can force which method searches for networks:
  • Linux: nmcli, iw, iwlist
  • Windows: netsh
• Tested on
  • Windows 10/11
  • Ubuntu Ubuntu 22.04.3 LTS
  • RaspPi OS - Debian GNU/Linux 11 (bullseye) / Raspbian GNU/Linux 10 (buster)

ToDo:

• Identify Band (i.e 2.4 MHz / 5 Mhz) on Windows
• Radio identification for Linux (802.11xx)
• Add Apple MAC capability
• Create unit tests
