Hi Mikko,

java -jar target/gurux.dlms.push.listener.example-0.0.1-SNAPSHOT.jar -i WRAPPER -t Verbose

I tried to run java push listener example using the above command , and I updated the ip address and port number in the meter. when I click on push button I am not receiving the data on my local machine.Is there anything I missed out here?

Hi,

You should see "Client Connected" message in the trace if the media can establish the connection for your meter.

If you can't see it, then there is something wrong with the meter settings. Check the port number and IP address.

Check that firewalls are not blocking the messages. This is a quite common problem.

And below screenshot is the meter settings.Is there any other settings I have to update in meter?

Hi,

There is a client and server on the push example. When you press enter key, the client sends a push message to the server.

The push server doesn't establish the connection for the meter. The meter sends data to the server and the push listener parses the received data.

Hi Mikko,

I got the packets from the meter like this

How to convert this?

Hi,

Data is parsed correctly after you set the block cipher and authentication.
Check the GXDLMSPushListener.printData-method. It shows the received data.

}

This is hex trace using GXDLMSPushListener.printData-method .How to convert it into actual human readable form like Datet , time , Event name etc?

Hi,

You need to set the correct push objects to the Push object list.
https://www.gurux.fi/Gurux.DLMS.Objects.GXDLMSPushSetup

You can get the push object from the meter documentation or if you read the push object.

I believe that the first one is the Logical Meter Name. The second is the Push OBIS code. The third one is the Clock and the last one I don't know.

Mikko

To convert this hex trace to readable form is there any class is available like GXTranslator?
