Connecting with Interfaces

Interface Events

All Interfaces have the same four Events:

• OnTunnelRequest: Is Invoked when the Interface receives a Request. (GroupValueWrite, IndividualAddressRead, etc.)
• OnTunnelResponse: Is Invoked when the Interface receives a Response. (GroupValueReadResponse, MemoryReadResponse, etc.)
• OnAck: Is Invoked when the Interface receives an Ack.
• OnSearchResponse: Is Invoked when the Interface receives a SearchResponse.

IP-Interface

You can connect to an IP-Interface by using IP-Tunneling.

IKnxConnection _connIp = new KnxIpTunneling("192.168.0.108", 3671);
await _connIp.Connect();
await Task.Delay(5000);
await _connIp.Disconnect();

If you already have the IPEndPoint you can create the connection like this:

IPEndPoint endpoint = new IPEndPoint(IPAddress.Parse("192.168.0.108"), 3671);
IKnxConnection _connIp = new KnxIpTunneling(endpoint);

IP-Router

To connect to an IP-Router you don't need the ip or port.
You also don't need the methods connect or disconnect.

IKnxConnection _connIp = new KnxIpRouting(); // Will broadcast to "224.0.23.12"
await _connIp.Connect(); // start handling received telegrams
await _connIp.Disconnect(); // stop handling received telegrams

USB-Interface

ConnectedDeviceDefinition def; // See Device.Net on how to get ConnectedDeviceDefinition
IKnxConnection _connUsb = new KnxUsbTunneling(def);
await _connUsb.Connect();
await Task.Delay(5000);
await _connUsb.Disconnect();

For now you will have to open ETS to make it work.
Often you can't connect to the usb interface without ets.

Search for Interfaces

You can search for Interfaces in your Local Network.
Please use IP-Routing for searches (do not connect with IP-Tunneling to broadcast IP).

KnxIpSearch _connIp = new KnxIpSearch();
_connIp.OnSearchResponse += HandleSearchResponse;
_connIp.Search();

private void HandleSearchResponse(MsgSearchResp message)
{
    Debug.WriteLine($"Found: {message.FriendlyName} (PA: {message.PhAddr.ToString()})");
}
