Decode PDU using shortname

Hello!

Recently, I’ve been trying to decode an information report packet with the PDU interface type, but the value always comes out as null, even though the GXDLMSTranslator decodes it correctly. I would like to know if this is indeed as it should be. I’m using the library version 9.0.2503.2001 for .NET.

Hello,

Here is an example:
18000202443002443802050000444402040500000000050000000005000000000500000000

Hi,

Short name referencing is not very good with notifications. You need to add COSEM objects manually and change the object type, logical name, and address. Use this as a template:

var client = new GXDLMSSecureClient(false, 0, 0, Authentication.None, null, InterfaceType.PDU);
client.Objects.Add(new GXDLMSData(, 0x4430 - 8));
client.Objects.Add(new GXDLMSData(null, 0x4438 - 8));
var data = "18000202443002443802050000444402040500000000050000000005000000000500000000";
GXReplyData rd = new GXReplyData();
GXReplyData nd = new GXReplyData();
client.GetData(GXDLMSTranslator.HexToBytes(data), rd, nd);
List<KeyValuePair<GXDLMSObject, int>> list = new List<KeyValuePair<GXDLMSObject, int>>();
client.ParseReport(nd, list);
