Hi guys!
When reading GXDLMSClock, the response from the hardware is an empty HDLC packet:
SEND:
GXDLMSClock clock = new GXDLMClock();
byte[] obj = client.Read(clock, 2);
reader.ReadDLMSPackage(obj, reply);

Why am I getting an empty package?

Hi,

The meter should return the time of the clock. Check first that the clock object is available on the association view.

Then try to remove DeltaValueEncoding from the proposed conformance. Something like this:

client.ProposedConformance &= ~Conformance.DeltaValueEncoding

This must be done before you establish the connection to the meter.

Miko I did it!
~~~
I missed a part of the code:
...
this.logger.log_msg("GetApplicationAssociationRequest");
foreach (byte[] it3 in client.GetApplicationAssociationRequest()) {
reply.Clear();
reader.ReadDLMSPacket(it3, reply);
}

client.ParseApplicationAssociationResponse(reply.Data);
...

I read serial number!!! Yahuu...!!!!
Many thanks to you and your group!
