Yes I am doing that

while reading innvocation counter, then disconnecting it.

Then new AArq request for profile read.

Hi mikko, a little update

i tried running .net version of gurux console app but was getting dependency issue.

I tried in my app, I am able to read invocation counter using PC mode and able to set it, but i get Disconnect Mode error in making aarqrequest while reading anything in Us mode.

this.settings.client.UseLogicalNameReferencing = true;
this.settings.client.InterfaceType = read.mediaType == MediaType.TCP ? InterfaceType.WRAPPER : InterfaceType.HDLC;
this.settings.client.ClientAddress = read.ClientId;
this.settings.client.ServerAddress = read.ServerId;

this.settings.client.Password = ASCIIEncoding.ASCII.GetBytes(read.Password);
this.settings.client.Authentication = Authentication.High;
this.settings.client.Ciphering.Security = Security.AuthenticationEncryption;

this.settings.client.Ciphering.SystemTitle = GXCommon.HexToBytes(AsciiToHex(read.SystemTitle)); // assuming default
this.settings.client.Ciphering.SecuritySuite = Gurux.DLMS.Objects.Enums.SecuritySuite.Suite0;
this.settings.client.Ciphering.AuthenticationKey = GXCommon.HexToBytes(AsciiToHex(read.AuthenticationKey));
this.settings.client.Ciphering.BlockCipherKey = GXCommon.HexToBytes(AsciiToHex(read.BlockCipherKey));
this.settings.client.Ciphering.InvocationCounter = counter + 1;
if (!string.IsNullOrEmpty(read.DedicatedKey))
{
this.settings.client.Ciphering.DedicatedKey = GXCommon.HexToBytes(AsciiToHex(read.DedicatedKey));

}
this.settings.client.Standard = Standard.India; // changing default
this.settings.client.Plc.MacDestinationAddress = UInt16.Parse("0"); // dont know yet
this.settings.client.ServiceClass = ServiceClass.Confirmed;
InitializeMedia(read);

am i missing something?
and is intervaltimeout mandatory for hdlc?

thanks

Hey mikko, i added 2 sec delay, still same error

Yes its wokring ccorreclty on GXdlms director, and same settinngs are working correctly for tcp through my code. Only thing i am changing is interface type and media object with GXSerial settings.

In that also its working correctly for getting innvocation counter using HDLC, only US mode connection and reading is giving me this error
