type BSS Uses

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.

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

type BSSStatus Uses

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 Uses

func (s BSSStatus) String() string

String returns the string representation of a BSSStatus.

type Client Uses

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 Uses

func New() (*Client, error)

New creates a new Client.

func (*Client) BSS Uses

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

BSS retrieves the BSS associated with a WiFi interface.

func (*Client) Close Uses

func (c *Client) Close() error

func (*Client) Interfaces Uses

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

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

func (*Client) StationInfo Uses

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

StationInfo retrieves all station statistics about a WiFi interface.

type Interface Uses

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

    // 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.

    // 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.
