Kaenx.Konnect

=================

Nuget Package is availible.

Kaenx.Konnect is a library to connect to a KNX Interface.
Its supports IP Tunneling, USB* and IP Routing*.

*Not implemented yet

Connect to the Interface via IP

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

Search for KNX IP Interfaces

IKnxConnection _connIp = new KnxIpTunneling("224.0.23.12", 3671, true); //Use sendBroadcast to send Searchrequest to all Network Interfaces on the PC
_connIp.Send(new MsgSearchReq(), true); // true to ignore if connection ist connected

Connect to the Interface via USB

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();

Connection via USB is not widly implemented yet.

Connection Events

There are 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.

Bus Device

Create a Bus Device to read Property or Memory from it. Also you can restart it.

BusDevice dev = new BusDevice("1.1.2", _connIp);
await dev.Connect();
byte[] data = await dev.MemoryRead(16495, 255);
string mask = await dev.DeviceDescriptorRead(); //Returns Mask Version like MV-0701, MV-07B0, ...
string serial = await dev.ResourceRead<string>("DeviceSerialNumber"); //Returns SerialNumber of Device
byte[] serialbytes = await dev.ResourceRead("DeviceSerialNumber"); //Returns SerialNumber of Device as Byte Array
await dev.Restart();
await dev.Disconnect();

Bus Common

Use this Class for common tasks on the bus like IndividualAddressRead or GroupValueWrite.

BusCommon bus = new BusCommon(_conn);
await bus.IndividualAddressWrite(UnicastAddress.FromString("1.1.6"));
await bus.GroupValueWrite(MulticastAddress.FromString("1/4/3"), 0x1);
await bus.GroupValueWrite(MulticastAddress.FromString("1/4/4"), new byte[] { 0x1, 0x23 });

Many thanks go to @xp-development and his Code from Automation.KNX which was the base code for my lib.
