scampi

scampi is a simple tool for Linux that allows you to use your web-cam to scan QR codes. It can add WiFi connections encoded as QR codes directly to NetworkManager.

The name desugars to something like scan cam wifi.

Note

Read more about hacking network-manager with zbus.

Usage

By default it only prints out the scanned data. Provide -w option to add the connection to NetworkManager.

To print the decoded QR code:

cargo run

To scan a QR code and add the decoded WiFi connection to NetworkManager:

cargo run -- -w -i wlan0

The default interface (-i) is wlan0, so if in fact your WiFi interface is wlan0, you can omit the '-i` options.

Help

cargo run -- --help

Caveats

• Only works with wpa-psk for now.
• No UI.
