Gurux DLMS for Java

Hello everyone,

Sorry for my ignorance but I am new to Gurux. I am trying to read from meter using Gurux component over TCP. I have all required information to do so. I used Gurux Director to successfully read the data, but I have really hard time reproducing what Gurux Director does into Java code. I am trying to combine gurux.dlms.java with gurux.net.java but I cannot find the connection.
Can anyone could point me to the right direction?

Thanks

Hi,

You should try with gurux.dlms.client.example.java.
It's small example that reads all objects from the meter.
You can get that from github.

Thanks for your reply Mikko. I managed to move forward with it but now I am stuck while adding meter serial number. I have this line of code "dlms.setServerAddress(GXDLMSClient.getServerAddress(32360809));" but this gives me an error "java.lang.StringIndexOutOfBoundsException: String index out of range: -5". Do you know what am I doing wrong?
