I am using python main.py -S /dev/ttyACM0 -a NONE to acquire data using gurux python. I am getting limited outputs, all class 1 data(Serial number, time etc). The voltage, current etc, which are class 3, are not accessible using this. We are getting these data using DLMS Client GUI but not getting using Gurux python package. How should I modify my command to get that using Gurux Python?

Hi Mikko,

I send you the log from the gurux serial library that I had today.
I tried to read the Profile Generic billing of the last month with writing access.
The phone and the meted are sending the packages and getting the info but at some point, the meter did not answer and then the library resend the last request packet, after that i only receive trash packets and after a while I receive a ViolatedAccess packet.

DLMS on RS485 ( Energy and Instantaneous Paramet Paramer needs)

Our Setup:
Any Serial/HyperTerminal RS485 Client sends the Known RS485 Frame to get the Response from the Secure (Apex150 DLMS RS485 meter).

When passing the serial port as an argument in Linux to the GXSerial constructor, it is working fine. However this error occurs for Windows:

Exception in thread "main" java.lang.Exception: The handle is invalid.

at gurux.io.NativeCode.openSerialPort(Native Method)
at gurux.serial.GXSerial.open(GXSerial.java:526)

It seems like the library can't handle Windows COM ports?

I was wondering if there is a way to communicate with n meters and 1 comfort unit during Glux serial communication.

Hi, I would like to report a problem with the gurux.serial.android package.

This package is old (last updates from 2017) and not updated so there are some features that are required for newer Android versions.
I would like to ask if it's possible for you to update your project or if I can make a pull request for your project with the features updated (I personally cloned the project and made the updates).

Hi,
i am enable to find DTR control configuration in Gurux DLMS director . Basically to enable and disable DTR signal manually.
I was hoping it should be provided under Flow control tab , but options there are not clear to me.

Kindly provide info on how to control DTR signal in Gurux DLMS director Serial configuration.

I am currently working with VisualBasic.Net and at the method:

ReadDLMSPacket(data as Byte(),ByRef reply as GxReplyData) I can´t go further than:

succeeded = _Media.Receive(p)
If Not succeeded Then
Throw New Exception("Failed to receive reply from the device in given time.")

The variable succeded is always false.

I am with a DDZ1513 Inhemeter.

I uploaded a picture of the variable 'Media'

Dear Sir,

I am using Gurux Serial in c# For Downloading Smart Meter Every data is showing write but Meter Clock showing Different from the meter Clock .
(GXDLMSSecureClient)
GXDLMSClock it = new GXDLMSClock("0.0.1.0.0.255");
object obj2 = Read(it, 2);

Where's GXDLMSDirector showing Correct clock value;

Thanks
Shekhar

I am able to read meter, successfully able to read the data but since I am not closing the connection after each read, data I am receiving every-time is same.

I have to reset my controller to read the latest value.
And it is working perfectly but as per my application requirement, I cannot reset it everytime.

I tried to get it from DLMSDirector:
I got the thread:
7E A0 07 03 41 53 56 A2 7E

When I am sending this to meter via serial port, it is not disconnecting and I am getting same repeated meter values when I read the meter again.
