Hi,
I am trying to communicate with a smart meter over GPRS communication. I am using Gurux.DLMS.Push.Listener.Example.python to read the data from the meter. But I am getting below errors:

gurux_dlms version: 1.0.197
gurux_net version: 1.0.19
gurux_serial version: 1.0.21
TCP Server imx93:4060
Press any key to close the application.
trace:07:58:06 TraceTypes.INFO MediaState.OPENING
Media state changed. MediaState.OPENING

Media state changed. MediaState.CLOSING
trace:07:58:06 TraceTypes.INFO MediaState.CLOSED
Media state changed. MediaState.CLOSED
[Errno -2] Name or service not known

I have used below command arguments based on meter specifications:
-p 4060 -i WRAPPER -t Verbose -A 1111111111111111 -b 4444444444444444

Can you help me to figure out this?

Hi,

This should be working without problems. Name or service not known errors look odd. Do you have multiple NIC cards?

Can you add the error log here?

The board doesnt have multiple NIC. Im using a imx93 based board and running Gurux.DLMS.Push.Listener.Example.python on it. I could not find other error logs with respect to this.

I did another testcase , running GuruxDLMSPushExample on host PC as a push message sender and running Gurux.DLMS.Push.Listener.Example.python on imx93 board as push message listener (over Ethernet connection). Will it works this way? In my case, the connection did not establish between host PC and board.

Hi,
We don't have this board, but I believe that socket.gethostname() returns empty string.
Set the correct hostname, and I believe that this will work.

net.hostName = "Board IP address"
