Hi

Hi,

Use block cipher key. Current implementation uses same key for Broadcast and Unicast messages.

Security-Receive Frame Counter- unicast key => "0.0.43.1.0.255"
Security-Receive Frame Counter -broadcast Key => "0.0.43.1.1.255"

Is not difference between Broadcast and Unicast in code ?

Hi,

I'm sorry. There was a misunderstanding. Do you want to make a client or the meter?

Hi,

Yes, I can help you. This covirus-19 is causing some delays.
I'll try to release the example the latest tomorrow.

Hi Mikko,

I also trying to read objects from meter (gurux java). below is the client code

GXDLMSReader reader = null;
GXNet net = null;
Settings settings = new Settings();
settings.client.setInterfaceType(InterfaceType.WRAPPER);
settings.client.setUseLogicalNameReferencing(true);
settings.media = new GXNet();
net = (GXNet) settings.media;
net.setHostName(hostname);
net.setPort(7063);;
settings.client.setPassword("eeslekakgsl06abc");
settings.client.getCiphering().setSecurity(Security.AUTHENTICATION_ENCRYPTION);
settings.invocationCounter = "0.0.43.1.0.255";
settings.client.setAuthentication(Authentication.valueOfString("High"));
settings.readObjects.add(new GXSimpleEntry<String, Integer>("1.0.94.91.0.255", Integer.parseInt("2")));
.......
reader.initializeConnection();

I have not set InvocationCounter OBIS code at Gurux meter.
When I test Gurux meter it is working fine as it doesn't try to read invocation counter.
But when I am testing using gurux client, it get failed as invocation counter OBIS is not set.

Hi,

You can read Invocation counter adding command line parameter -v 0.0.43.1.1.255
There is updateFrameCounter method that handles this. Frame counter is an old name of Invocation counter.
