Hi Mikko,

Thanks for the reply. Could you kindly help on the below questions:

1) Is the Gurux.Client code is a single threaded model OR can my Thread Application be able to connect multiple IP's at same time using this gurux.client

2) How do we differentiate the LOAD_SURVEY vs DAY_SURVEY vs BILLING_SURVEY? Is it only by input arguments it differs or we have to write seperate code for these SURVEYS?

Hi,

You need to create own instance for each client. The reason for this is that data is not necessarily come in one packet. There is also connection depends settings. Example frame counters that are increased every time you send a message.

Profile generic data is handled in the same way. The content of the data is different.

Hi Mikka,

Thanks. We are able to setup locally. But when we try to connect the working STATIC IP through our command line method there are no response. Its connecting with Authentication: None, ClientAddress etc, but there are no response further. Its in Hung state.
The command used is: java -jar gurux.client.sample.jar -h StaticIP -p port -r sn

Hi,

Check that your IP address and port number are correct. Check also your firewall settings.
There is no difference are you connecting using the local or static IP address.

Hi Mikko, I could able to connect using GXDLMSDirector and could fetch data. PFA screen shot below.

But if i try the same using command line arguments, I am getting the below time out error message.
java -jar gurux.client.jar -h 117.231.125.245 -p 4059 -c 16 -s 1 -r sn
Authentication: None
ClientAddress: 0x10
ServerAddress: 0x1
Connection timed out: connect

If i compare the screen shot below, I need to feed values for the below fields. How do i that through the command arguments.

Start protocol: DLMS
Manufacturer: Indian Standard
Interface: WRAPPER
Media: Net

These are the mandate fields to fetch the data. Please provide your valuable thoughts.

Hi,

java -jar gurux.client.jar -h 117.231.125.245 -p 4059 -c 16 -s 1 -w

Hi Akash,

Please, create a new topic if you have a new question. I'm not receiving notifications from old topics like this. I accidentally notest your question.

There is only a client-side implemented for Android.
