hi,

I'm trying to build a modem for my project to read values like energy consumption, real and reactive power, etc, of a dlms based energy meter.
I'm confused as to which code i should use to achive the same.
i do have the following components.

1)esp 32 / esp 8266
2)ttl convertor
3)USB to rj11 convertor cable

My preferred coding platform is arduino ide version(2.0.4)

thank you

Hi,

You need the client example to read your meter. You can get it from here:

I propose that you use GXDLMSDirector and use it first with your meter. It will help you to understand the DLMS meters.

Sir,

Thank you for the fast response,
I would like to ask how GXDLMSDIRECTOR is going to help understand the meter and be useful for my project?

Thank you

Hi,

GXDLMSDirector will show the structure of COSEM objects in the UI and it's easier to understand the DLMS meters.

Sir,

I tried using GXDLMSDIRECTOR but i couldn't connect my meter to read any data,
Moreover i tried to compile the client.ino file and encountered

Compilation error: include/gxignore.h : No such file or directory

Thank you

Hi, This is the reason why…

Hi,

This is the reason why asked you to use GXDLMSDirector first. There are multiple parameters in DLMS and the meter doesn't reply if one of the parameters is different that the meter expects. What meter model you try to read?

If you are using ANSI C you need to copy src and include folders under the development folder to dlms folder. You can read more from here:
