The code which is available in github is all about socket programming for gurux dlms python framework.
I want to know whether there is any source code for serial port programming for gurux dlms python framework

Hi,

I believe that your python version is wrong. Try to run this as "python3 main.py".

Support for the serial port is added later.

Hi Mikko,

Hi Mikko,

We are testing it at the moment. We'll try to release it as soon as possible. I can't give any exact date.

I'm trying to connect via serial port but im getting errors.

Hi,

Serial port implementation for Python is not released yet. Only TCP/IP connection is released.

Mikko

Hi Mikko,

Hi Mikko,
Is python code ready for serial port?
Is it ready or still work in progress?

Thanks

Hi,

We released the first version last Friday. You can communicate over the serial port, but we are making a few changes so communication is possible using an optical head (probe). This version is released during this week.

BR,

Mikko

okay thanks Mikko

Hi Mikko,

Hi Mikko,
Recently you uploaded code for serial port communication.
how to run that Gurux.Serial.python-master?
I mean which file we have to run.
Thanks waiting for ur fast reply

Hi,

You don't run gurux-serial. You run it like this:
python Gurux.DLMS.Client.Example.python -s "SERIAL_PORT_TO_USE"

You need to update the serial port to correct one. We'll make a video tomorrow.

BR,

Mikko

Hi,

Hi,
we run the code like as u said but im getting this error.
please check it once.
And when your going to upload a video of this?
Thanks

HI,

run this:

pip install --upgrade gurux-serial
pip install --upgrade gurux-dlms

We are working with the video at the moment.

BR,

Mikko

Hi Mikko

Hi Mikko
Even though we gave correct port number we are getting this error.

Hi,

You need to change "UPDATE CORRECT PORT" to "COM1" or "Com3" in the example.py.

Mikko

Hi,

You should check this video.

Yes, but I need information from the manufacturer and model of the serial port.
Is that integrated to the PC or is it USB port?

It is a TriVector meter and I'm using USB port to connect to my PC.

I have the same error:

Hi pafcioz,

Please, if you have a new question, create a new topic.
This is not the same error. What version from Windows you are using? We might know the reason for this.

BR,

Mikko

Hi,

There is a new version (1.0.12) from gurux-serial where ASCII and UNICODE support is improved.
Let me know if you have problems.

updateAuthenticationMechanismName is fixed and a new version (1.0.17) is released. It'll fix the first image issue.

Can you run the app with -t Verbose parameter and send DisconnectRequest data. I need to check why meter is no reply.

Hi Mikko

Hi Mikko
Like U said in the video if we are running the code we are getting all values.
But we want individual values like if we send particular obs code we have to get that particular values.
We tried to run with -g while running but we are facing issues like

C:\Users\test.EMMYS1546\Desktop\Gurux.DLMS.Python-master\Gurux.DLMS.Client.Example.python>main.py -S COM3 -g \"0.0.1.0.0.255:1\"

ValueError: Invalid Logical name or attribute index.
Ended. Press any key to continue.

Thanks

Hi,

Get the latest version from GitHub. This is fixed.

Hi Mikko,

Hi Mikko,
We are getting values for the selected objects, But if we want all attributes of a single OBS code then how to do it.
Thanks,
Ram.

Hi,

You need to loop all object attributes and read them all. Check client example it does what you require.

BR,

Mikko

Hi Mikko,

Hi Mikko,
We didn't find anything in client example regarding loop of object attributes. Can you tell the exact file location where it is.
Thanks and Regards,
Ram.
