hi, is there any standard for HeartBeat packet (I mean packet that, the meter will send to
head-end periodically to keep connection alive) ?
and do you implemented this in c# version ?

Hi,

Call GXDLMSClient.GetKeepAlive-method. It will do this.

thank you for response. I

thank you for response. I already had looked at your KeepAlive method. it's try to read an object.

public byte[] GetKeepAlive()
{
Settings.ResetBlockIndex();
if (UseLogicalNameReferencing)
{
return Read("0.0.40.0.0.255", ObjectType.AssociationLogicalName, 1)[0];
}
return Read(0xFA00, ObjectType.AssociationShortName, 1)[0];
}

but we have meter that sends its KeepAlive in this format:
0001000100000003011113

hence, I want to know is there standard for it?

Hi,

There is a keepalive in HDLC standard, but there is no standard solution for WRAPPER.
Your meter is using the manufacturer-specific solution to keep the connection up. It's better to read something from the meter to keep the connection up than use a manufacturer-specific solution like this.
This manufacturer-specific solution might cause problems later if DLMS standard changes.
