Hi everyone.

How can I pull and read archive data from DLMS meter, namely Itron SL7000?

I'm trying to read the data from my ISKRA AM550 but I still only manage to get binary response that I cannot interpret.

I'm trying to use the GuruX simulator to simulate a meter with AuthenticationEncryption and HighGMac security. When specifying the `-w` wrapper parameter on the simulator I am getting `Connection permanently rejected` when I try to connect to the meter. Without using this parameter I can connect to the meter. With the meter simulated in wrapper mode, I can connect to client 16 (public client) of the meter but I can't connect using client 1 access. So it appears that there is an auth issue.

The meter I am simulating is a CLOU CL710K22.

Good morning,

I am trying to translate with the Python library a frame received from a meter Zener BK04ZENNER01.

If I introduce data in the program Gurux Director, I manage to translate it well.
Without key:

Hello, I tried to run example from your github, but the exception occurred. In the code below, the connection was successfully established, but when trying to read the association, it immediately throws an exception. But with GXDLMSDirector association was read successfully.

how can I switch between Tcp Server and Tcp Client on smart meter with dlms?

I'm building a automated billing system for a building with about 60 tenants/meters. I need to read the energy usage [kWh] from meters, bill the users and turn off their electricity if they don't pay the bill in time.
I want to keep it cheap and simple and communicate with the meters over a simple local bus system (I'd prefer RS485 but others possible). The meters are all close together and if the bus system supports daisy chaining, wiring is easy.

HI SIR,
I recently started working on single-phase dlms meter, i compiled my utility (which contain GURUX library code) in linux terminal, from meter side got some response but can't able to get specific value(i.e voltage) from the meter it's coming "UNDEFINED OBJECT",

could anyone help me to move further.

(Assume here my laptop act as CLIENT and DLMS meter as SERVER)

Hello, i tried to read Data object via GXDMLSDirector and it was okay. But when i tried to read it with .NET library it was exception "Exception response. "Service not allowed"-exception. Operation not possible".

GXDLMSData _data = new GXDLMSData("0.0.96.1.0.255");
_сlient.Read(_data, 2);

I did not read association, so i think is there missed parameters in GXDLMSData instance that i need specify?

There is a problem. When polling the Meter correctly polled only on the first cycle, on the second authorization does not pass.
After studying the log it turned out that the problem is in the transmitted value ProposedMaxPduSize - the first cycle passes the value 65535, authorization passes, but the second cycle is 100 and the counter responds with an error.
As I understand this value is returned by the device itself as the NegotiatedMaxPduSize parameter, and your stack then uses this value.
It turns out that this is an error in the device?
