wpa-connect

Package provides API for connection Linux device to Wi-Fi Network.

wpa-connect communicates with WPA supplicant over D-Bus (linux message bus system).

This package was developed as part of IoT project in order to add Wi-Fi connectivity to headless Raspberry Pi like devices. No need for connman or Network Manager be installed.

Setup

On Linux:

wpa_supplicant service should run with -u flag in order to enable DBus interface. Run it as Linux service before first call to wpa_supplicant. Otherwise system will start it automatically without -u flag.

Systemd service configuration file - /etc/systemd/system/[e-mail]

[Unit]
Description=WPA supplicant for %i

Examples

Connect to Wi-Fi network

import wifi "github.com/mark2b/wpa-connect"

if conn, err := wifi.ConnectManager.Connect(ssid, password, time.Second * 60); err == nil {
	fmt.Println("Connected", conn.NetInterface, conn.SSID, conn.IP4.String(), conn.IP6.String())
} else {
	fmt.Println(err)
}

Scan for Wi-Fi networks

import wifi "github.com/mark2b/wpa-connect"

if bssList, err := wifi.ScanManager.Scan(); err == nil {
	for _, bss := range bssList {
		print(bss.SSID, bss.Signal, bss.KeyMgmt)
	}
}
