Gurux Server

Is it possible to read the Gurux.server.example on linux through another device using a serial port? I have tried it through localhost, and it worked. However, when using the serial port, it becomes like this:

Gurux.DLMS.Client.Example.Net -r sn -h 0.0.40.0.2.255 -p 4060 -S COM13 -t Verbose
Standard: DLMS

Disconnecting from the meter.

What command should I modify?

Thank you very much.

Hi,

Yes, that is possible. Your serial port (COM13) is invalid. In Linux serial ports are like this:

/dev/ttyS1

You need to check what serial ports are available in your distro.

I am currently utilizing the DLMS client net on my computer to access the Gurux server example running on Linux. The available port is COM13. Should I consider changing the port and host?

Hi,

Are you running your Linux in Windows subsystem (WSL)?

How you have connected your Linux and Windows serial ports?

Hello,

I apologize for the incomplete explanation. Currently, I am using the DLMS client net on my Windows computer to access the Gurux server example running on another device, which is a Linux-based Raspberry Pi.

I also attempted to communicate between Gurux.client and Gurux.server using Windows and a serial port. I have confirmed that the connection is successful, and commands from Gurux.client are being received (between two Windows devices) using Docklight: 1/22/2024 8:59:35:22 [RX] - 74 65 73 74 7E A0 07 03 21 93 0F 01 7E 7E A0 07 03 21 93 0F 01 7E

However, when executed through the command prompt (cmd):

E:\Gurux.DLMS.Net\Gurux.DLMS.Net-master\Gurux.DLMS.Client.Example.Net\bin\Release>Gurux.DLMS.Client.Example.Net.exe -r sn -h localhost -p 4060 -S COM6:9600:8None1 -t Verbose

Is there any command that I should change?

Hi,

I believe that your server is communicating with TCP/IP and your client is trying to connect with a serial port.

You haven't told the server what serial port it should use. What programming language are you using on the server side?

Hello,

For the server, I am using the Java programming language (gurux.dlms.server.example.java)

Hi,

I belive that you have started the example meter without arguments and it's using TCP/IP connection. You need to start server like this:

java -jar gurux.dlms.server.example.java-0.0.1-SNAPSHOT -S YOUR_SERIAL_PORT
