Hi
We have two L+G E450 meter which push data in different structures. I use Gurux.DLMS.Python in my software to parse this data, however it only works with one of the two meters.
I used the translator tool of Gurux Director to parse and inspect the raw data to further analyze the problem.

First the output of the meter data my Gurux based software is able to parse:

sudo python3 main.py -S /dev/ttyUSB2:300:7Even1 -t Verbose -i HdlcWithModeE -a High -P [0x0000000000] -s 1 -c 16
gurux_dlms version: 1.0.119
gurux_net version: 1.0.18
gurux_serial version: 1.0.18

Authentication: Authentication.HIGH
ClientAddress: 0x10
ServerAddress: 0x1
Standard: Standard.DLMS

Hello,

I have a DLMS meter that is pushing data from their side to my GXDLMSPushListener, and in the objects list of the push data is:
GXDLMSData with AttributeIndex of 2 and DataIndex of 0,
GXDLMSRegister, with AttributeIndex of 0 and DataIndex of 0.

Hi, Mikko!

I try this:
CGXDLMSVariant str1(std::string("hello"));
CGXDLMSVariant str2(std::string("hello"));
bool eq1=str1.Equals(str2); //returns false but these variables are equal

CGXDLMSVariant v1(99);
v1.ChangeType(DLMS_DATA_TYPE_UINT16);
CGXDLMSVariant v2(99);
v2.ChangeType(DLMS_DATA_TYPE_UINT16);
bool eq2=v1.Equals(str2); //returns false but these variables are equal

Is it OK? Which data type must be CGXDLMSVariant for correct work Equals() method?

Thanks!

Hello,

Is it possible to run multiple server examples (on different devices) and read them via single RS485 port? For example: laptop 1 and 2 are running server examples and laptop 3 reads from both of them (using different serial numbers). All devices are connected via rs485 to USB adapters to each other.

I get something like this when I try to connect. If only one server is running, then it connects and works normally.

Hi, Mikko!
I create ProfileGeneric object (0.0.96.11.5.255). It has 5 columns.
I check "All" radio button in DLMSDirector 8.2.2202.0901.
If object has 23 rows - OK
If object has more than 23 rows (for example 24 rows) - infinite requests of data.

Hi,
I am completely new to meter reading and DLMS. I have been tasked with reading data from an electric meter.
I have an ip address and a port number.
The meter is Meteronic MT318.
I have been provided a program that already communicates with the meter.
Here are some of the logs of the program:

Hi,

could you give me an example arduino code to get buffer data [Array] from load profile?

Hello,

I have few questions:

1) Is it possible to change meter's server address using gurux cpp library?
2) How does 5-pass authentication works? I am reading Shenzhen CLOU electronics meter documentation and they state that they use HLS-5 pass authentication with challenge mechanism. Is that GMAC authentication? If so, what kind of data do we need to know in order to connect to establish secured connection. Authentication, blockCipherKeys?

Differnce between GCM and GMAC
Dear Sir,
As mentioned in Green book that the below are input and output of GCM

Input to GCM Block is
For Authenticated Encryption

1. Plain Text
2. Encryption Key
3. Authentcated Key
4. Nounce(IV || System Title)

Output:
1. Ciphered Text
2. Authentication Tag

What is Input and Ouput of GMAC?
