WiFi Scanner

[NPDedyukhin]

Good afternoon!

When we connect the Raspberry Pi to a WiFi network, we can enter a command in the console to see a list of available networks:

iwlist wlan0 scan

What should a python script look like that will do the same?

Thanks for the tip.

I figured out how to do it.

The code is as follows:

Code: Select all

import os 
myCmd = 'iwlist wlan0 scan | grep "ESSID"' 
os.system (myCmd)

But now the problem is that if this script is run without using "sudo" - it gives information only about my network.

Other networks can only be seen if you start it manually using "sudo".

What's the problem starting the script with 'sudo' ? Here is the example from Peppy player:

And is iwlist the old command and the newer iw command has more features?

Code: Select all

sudo iw wlan0 scan | egrep 'SSID|signal'
