Class ConnectionStateChangedEventArgs

Definition

Namespace:

Tizen.Network.WiFiDirect

Assembly:

Tizen.Network.WiFiDirect.dll

An extended EventArgs class which contains the changed connection state during connecting or disconnecting the peer device. This event is triggered when the connection state with a specific peer device changes.

public class ConnectionStateChangedEventArgs : EventArgs

Inheritance

object

System.EventArgs

ConnectionStateChangedEventArgs

Remarks

This event is raised by the ConnectionStateChanged event. Use this event to monitor connection progress and handle connection state changes such as:

• Connection request initiated
• WPS (Wi-Fi Protected Setup) in progress
• Connection established
• Disconnection initiated or completed
• Group creation/destruction events

Example usage:

peer.ConnectionStateChanged += (sender, e) =>
{
    if (e.Error == WiFiDirectError.None)
    {
        switch (e.State)
        {
            case WiFiDirectConnectionState.ConnectionRsp:
                Console.WriteLine($"Connected to peer: {e.MacAddress}");
                break;
            case WiFiDirectConnectionState.DisconnectRsp:
                Console.WriteLine($"Disconnected from peer: {e.MacAddress}");
                break;
        }
    }
    else
    {
        Console.WriteLine($"Connection error: {e.Error}");
    }
};

Properties

Error

The Wi-Fi Direct operation result. Indicates whether the state change was successful or if an error occurred.

Declaration

public WiFiDirectError Error { get; }

Property Value

Type	Description
WiFiDirectError	None if successful, otherwise the specific error code.

Remarks

This event is raised by the ConnectionStateChanged event. Use this event to monitor connection progress and handle connection state changes such as:

• Connection request initiated

• Connection established
• Disconnection initiated or completed
• Group creation/destruction events

Example usage:

peer.ConnectionStateChanged += (sender, e) =>
{
    if (e.Error == WiFiDirectError.None)
    {
        switch (e.State)
        {
            case WiFiDirectConnectionState.ConnectionRsp:
                Console.WriteLine($"Connected to peer: {e.MacAddress}");
                break;
            case WiFiDirectConnectionState.DisconnectRsp:
                Console.WriteLine($"Disconnected from peer: {e.MacAddress}");
                break;
        }
    }
    else
    {
        Console.WriteLine($"Connection error: {e.Error}");
    }
};

MacAddress

The MAC address of the peer device whose connection state changed. This uniquely identifies the peer device in the connection event.

Declaration

public string MacAddress { get; }

Property Value

Type	Description
string	The MAC address string of the peer device (e.g., "AA:BB:CC:DD:EE:FF").

Remarks

This event is raised by the ConnectionStateChanged event. Use this event to monitor connection progress and handle connection state changes such as:

• Connection request initiated
• WPS (Wi-Fi Protected Setup) in progress
• Connection established
• Disconnection initiated or completed
• Group creation/destruction events

Example usage:

peer.ConnectionStateChanged += (sender, e) =>
{
    if (e.Error == WiFiDirectError.None)
    {
        switch (e.State)
        {
            case WiFiDirectConnectionState.ConnectionRsp:
                Console.WriteLine($"Connected to peer: {e.MacAddress}");
                break;
            case WiFiDirectConnectionState.DisconnectRsp:
                Console.WriteLine($"Disconnected from peer: {e.MacAddress}");
                break;
        }
    }
    else
    {
        Console.WriteLine($"Connection error: {e.Error}");
    }
};

State

The Wi-Fi Direct connection state of the peer. Represents the current state in the connection lifecycle.

Declaration

public WiFiDirectConnectionState State { get; }

Property Value

Type	Description
WiFiDirectConnectionState	A WiFiDirectConnectionState enum value indicating the current connection state.

Remarks

This event is raised by the ConnectionStateChanged event. Use this event to monitor connection progress and handle connection state changes such as:

• Connection request initiated
• WPS (Wi-Fi Protected Setup) in progress
• Connection established
• Disconnection initiated or completed
• Group creation/destruction events
