Difference between python and C#

Hello to everyone,

I'm using Gurux Python and I'm trying to make the first serial communication only with snrmRequest() and aarqRequest().

With c# I'm setting the public client like this:
this.ClientPublic = new GXDLMSClient();
this.ClientPublic.UseLogicalNameReferencing = true;
this.ClientPublic.InterfaceType = InterfaceType.HDLC;
this.ClientPublic.ClientAddress = 16;
this.ClientPublic.Password = GXCommon.HexToBytes("xxxxx");
this.ClientPublic.Authentication = Authentication.None;
this.ClientPublic.ServerAddress = GXDLMSClient.GetServerAddress(1, 16);
this.ClientPublic.ProposedConformance = Conformance.GeneralProtection | Conformance.Get |
Conformance.Set | Conformance.Action;
this.ClientPublic.CtoSChallenge = GXCommon.HexToBytes("CPLc2s00");
this.ClientPublic.Standard = Standard.Italy;
and the aarqRequest() works;

I'm trying to configure in the same way the python library but the aarqRequest() doesn't work:
self.clientPublic = GXDLMSClient()
self.clientPublic.clientAddress = 0x10
self.clientPublic.proposedConformance = Conformance.GENERAL_PROTECTION | Conformance.GET | Conformance.SET | Conformance.ACTION
##self.clientPublic.useLogicalNameReferencing = True
self.clientPublic.interfaceType = InterfaceType.HDLC
self.clientPublic.authentication = Authentication.NONE
self.clientPublic.ctoSChallenge = 'xxxxx'
self.clientPublic.password = 'xxxxx'
self.clientPublic.serverAddress = GXDLMSSecureClient.getServerAddress2(1, 16, 0)
self.clientPublic.useLogicalNameReferencing = True

What is the difference between these 2 configuration?

Thanks
