WiFi Share and Connect with QR

Xiaomi Android phones has started using QR to use WiFi for sharing. The idea was to get started with Bash, from Android to PC or PC to Mobile, and use Interface for zenity, QR for zbar and qrencode, and nmcli from Network-Manager for Network. For security, you can use WPA, WPA2, WEP, Open and share with the Hidden Network. QR code does not support LDAP Network and VPN. Android can easily generate WiFi QR, iOS via Shortcuts apps.

• Sorry for Code Clean, Rebase and force upload.

v0.1-1 is using bash reading replace with nmcli

v0.1-2 shellcheck pass for #9

Generate WIFI QR

it's easy, we check /etc/NetworkManager/system-connections and generate WPA, WEP and Open, also HIDDEN network.

now using nmcli you can use command line via

• wifi-qr t for terminal only QR.
• wifi-qr g for PNG file QR export. or using graphics menu.
• Share saved WiFi

Scan and Connect with QR Code

It's like Android QR Scanner, scan and connect to network. iOS is just see password from terminal

• wifi-qr s for auto connect.
• wifi-qr q for show SSID, PASS and Connect. or using graphics menu
• Scan and connect

Todo list

• QR Generate with GUI
• QR Generate with Terminal
• QR Scan and Auto Connect
• QR Image File Scan and Auto Connect
• It's Not Wifi QR
• This network is not available.
• Migration to nmcli
• QR Share Hidden Network
• QR Scan Auto Connect Hidden Network
• icons
• Password with special characters needs to be unquoted
• Additional LDAP Login

Improve

All is done Just need for LDAP and LEAP We will come back when QR Code and Scanner support LDAP and relative thing.

nmcli c add type wifi con-name <connect name> ifname wlan0 ssid <ssid>
nmcli con modify <connect name> wifi-sec.key-mgmt wpa-psk
nmcli con modify <connect name> wifi-sec.psk <password> 
nmcli con up <connect name>
