Hi There,
We are facing problem of comport gets hanged.
At first instance meter gets connected on comport and reading completed successfully.
After some reading sessions, comport gets hanged randomly with GuruX Serial media over DLMS protocol.

Please share the solution if any.
Thanks in Advance...

I want to read meter data through uart. how to use this dlmsclientexample.
Please explain step by step

Thanks for the answer, that works perfectly. Once one makes the query, where does it recover the value that the OBI returns ???

ret = com_read(&gn.base, 2);

I have that query configured to give me the voltage. When I print the response from the serial port, the value reaches me perfectly. But I don't know what method of the object has that value saved, to use in the program.

THANK YOU!

Hello, I am using the library for arduino .C and the client.ino example and I have a problem the meter does not respond. I am seeing the packages they send and there is a difference between what the GXDLMSDirector and the arduino sends:

DATA SENT GXDLMSDirector : 7E A0 08 02 23 03 93 3E 74 7E

RESPONSE SL7000 : 7E A0 23 03 00 02 00 23 73 C0 48 81 80 14 05 02 00 80 06 02 00 80 07 04 00 00 00 01 08 04 00 00

-------------------------------------------------

DATA SENT ARDUINO EXAMPLE : 7e a0 07 23 03 93 b7 12 7e

RESPONSE SL7000 : NOT RESPONSE

Im running my python library but im getting error like this
PFA

I am using the Gurux DLMS client example in Java (gurux.dlms.client.example.java). I have specified the required input parameters and it was able to read meter. However, when closing the serial port, there is always a Java exception error generating a hs_err_pidxxxx.log.

The meter model is from TESSERACT and I am using Windows 10 (64bit).

I'm trying to connect to SL7000 Actaris using Gurux in serial mode, but I have this error

java.lang.Exception: Descripteur non valide

at gurux.io.NativeCode.openSerialPort(Native Method)
at gurux.serial.GXSerial.open(GXSerial.java:521)

I don't know how to resolve this issue

Hello,

We are looking to implement a tier component for file send and receive management in rs232.
Gurux.serial is on the table and being analyzed. As our application will be constantly listening to incoming files in reception I wanted to know the implementation that you recommend in this case. The application could be listening on hundreds of COM port. And manage multiple simultaneous file receptions.

I am new to C#Sharp and i am developing a program to read or program energy meter via serial port.I connect to the meter at 300 baudrate and do initial handshake
At this stage i can connect to the meter after initial /?!<CR>LF> command.The problem i have is when i am attempting to send the ACK command together with baudrate change-over.

Hello Team.

I need to extract data ( Voltage, Current etc) from EM101+ Energy meter. To extract data am using Guru GXDLMSDIRECTOR. But in that explorer can't able to find L & T device in manufactures list.

Kindly advise and help to extract the data for further process.

Regards
Srini
