Hi, I am successfully receiving AARE Response using Java.
When I try to read energy parameter using this code

GXDLMSRegister obj = new GXDLMSRegister("1.0.1.8.0.255");
byte[][] bytes= client.Read(obj, 2);

I just receive the bytes array which should send to the meter for reading energy, but nothing is sending to the meter (checked using Wireshark), please guide me the way to read a single parameter.

Thanks.

Is it possible to autodetect class id ? My requirement is that user enters logical name (like for example "1.0.1.8.0.255"), program determines class id and then reads value of this register. Problem is that when reading register value I need to know class_id (another name for class_id is object type). The goal is to minimize amount of configuration information. I know that there are special registers named association views (like for example 0.0.40.0.0.255). During testing GXDLMSDirector I noticed that I dont have the option to read association only for required register.

I am integrating gurux.dlms.cpp library into our application which will be simultaneously reading register values from multiple meters. Typically this application will be used for communication with 20 meters but it is possible that number of meters will be 40 or 60. We want meter readout to be as fast as possible therefore we use multiple threads, one thread for each meter / comport. In every thread I am creating separate instances of CGXDLMSClient & CGXCommunication classes. Is gurux library thread-safe ?

Hi,

what is the length of data in ENUM data type ?

Thanks

Hi,

In CGXDLMS::HandleGetResponse(CGXDLMSSettings& settings,CGXReplyData& reply,int index) condition ((reply.GetMoreData() & DLMS_DATA_REQUEST_TYPES_FRAME) == 0) is always true and value of reply.m_Command setting to DLMS_COMMAND_NONE even whole block is read.

Best regards

I can read date and time but i can't write Date and Time to meter actually i get DLMS_ERROR_CODE_OK but when i read again date and time are not change.
Clint Adress 0x01
// already connected and read Association View.
int index=2;
time_t tm1 = time(NULL);
struct tm dt;
localtime_s(&dt, &tm1);
CGXDateTime aa(dt);
aa.SetSkip(DATETIME_SKIPS_NONE);
CGXDLMSVariant ValueSet(aa);
std::string str="0.0.1.0.0.255:"
CGXDLMSObject* obj = cl.GetObjects().FindByLN(DLMS_OBJECT_TYPE_ALL, str);

Hello,

I have a problem with reconnecting to the meter after communication error.

I'm using the code from the example with GXDLMSReader to connect to Landis Gyr ZMQ meter. I can open the connection, read data and then close - then every 20 seconds repeat - everything works fine.

The connection is via RS232 but with MOXA NPort converter in Real COM mode.

Hi Mikko

Hello. I compiled the example and decided to try to connect with the meter.

Parametrs:
Gurux.DLMS.Client.Example.Delphi.exe -r ln -c 48 -s 1 -h 192.168.1.115 -p 10005 -P 12345678 -a Low -C None

A connection error occurs. By log file it is clear that the address of the server takes 1 byte:
7E A0 07 03 61 93 69 47 7E

But my address should occupy 2 bytes and the command should look like this:
7E A0 08 22 03 61 93 B3 AE 7E

Hello.
When receieve this data from meter, Gurux, throwing System.OutOfMemoryException

Data: 7E A0 0A 07 00 22 2A 65 97 58 36 7E
