Types

type BSS

type BSS struct {
	// The service set identifier, or "network name" of the BSS.
	SSID string

	// The BSS service set identifier.  In infrastructure mode, this is the
	// hardware address of the wireless access point that a client is associated
	// with.
	BSSID net.HardwareAddr

	// The frequency used by the BSS, in MHz.
	Frequency int

	// The interval between beacon transmissions for this BSS.
	BeaconInterval time.Duration

	// The time since the client last scanned this BSS's information.
	LastSeen time.Duration

	// The status of the client within the BSS.
	Status BSSStatus
}

A BSS is an 802.11 basic service set. It contains information about a wireless network associated with an Interface.

type BSSStatus

type BSSStatus int

A BSSStatus indicates the current status of client within a BSS.

const (
	// BSSStatusAuthenticated indicates that a client is authenticated with a BSS.
	BSSStatusAuthenticated BSSStatus = iota

	// BSSStatusAssociated indicates that a client is associated with a BSS.
	BSSStatusAssociated

	// BSSStatusIBSSJoined indicates that a client has joined an independent BSS.
	BSSStatusIBSSJoined
)

func (BSSStatus) String

func (s BSSStatus) String() string

String returns the string representation of a BSSStatus.

type Client

type Client struct {
	// contains filtered or unexported fields
}

A Client is a type which can access WiFi device actions and statistics using operating system-specific operations.

func New

func New() (*Client, error)

New creates a new Client.

func (*Client) BSS

func (c *Client) BSS(ifi *Interface) (*BSS, error)

BSS retrieves the BSS associated with a WiFi interface.

func (*Client) Close

func (c *Client) Close() error

Close releases resources used by a Client.

func (*Client) Interfaces

func (c *Client) Interfaces() ([]*Interface, error)

Interfaces returns a list of the system's WiFi network interfaces.

func (*Client) StationInfo

func (c *Client) StationInfo(ifi *Interface) ([]*StationInfo, error)

StationInfo retrieves all station statistics about a WiFi interface.

type Interface

type Interface struct {
	// The index of the interface.
	Index int

	// The name of the interface.
	Name string

	// The hardware address of the interface.
	HardwareAddr net.HardwareAddr

	// The physical device that this interface belongs to.
	PHY int

	// The virtual device number of this interface within a PHY.
	Device int

	// The operating mode of the interface.
	Type InterfaceType

	// The interface's wireless frequency in MHz.
	Frequency int
}

An Interface is a WiFi network interface.

type InterfaceType

type InterfaceType int

An InterfaceType is the operating mode of an Interface.

const (
	// InterfaceTypeUnspecified indicates that an interface's type is unspecified
	// and the driver determines its function.
	InterfaceTypeUnspecified InterfaceType = iota

	// InterfaceTypeAdHoc indicates that an interface is part of an independent
	// basic service set (BSS) of client devices without a controlling access
	// point.
	InterfaceTypeAdHoc

	// InterfaceTypeStation indicates that an interface is part of a managed
	// basic service set (BSS) of client devices with a controlling access point.
	InterfaceTypeStation

	// InterfaceTypeAP indicates that an interface is an access point.
	InterfaceTypeAP

	// InterfaceTypeAPVLAN indicates that an interface is a VLAN interface
	// associated with an access point.
	InterfaceTypeAPVLAN

	// InterfaceTypeWDS indicates that an interface is a wireless distribution
	// interface, used as part of a network of multiple access points.
	InterfaceTypeWDS

	// InterfaceTypeMonitor indicates that an interface is a monitor interface,
	// receiving all frames from all clients in a given network.
	InterfaceTypeMonitor

	// InterfaceTypeMeshPoint indicates that an interface is part of a wireless
	// mesh network.
	InterfaceTypeMeshPoint

	// InterfaceTypeP2PClient indicates that an interface is a client within
	// a peer-to-peer network.
	InterfaceTypeP2PClient

	// InterfaceTypeP2PGroupOwner indicates that an interface is the group
	// owner within a peer-to-peer network.
	InterfaceTypeP2PGroupOwner

	// InterfaceTypeP2PDevice indicates that an interface is a device within
	// a peer-to-peer client network.
	InterfaceTypeP2PDevice

	// InterfaceTypeOCB indicates that an interface is outside the context
	// of a basic service set (BSS).
	InterfaceTypeOCB

	// InterfaceTypeNAN indicates that an interface is part of a near-me
	// area network (NAN).
	InterfaceTypeNAN
)
