Hello,

We are trying to establish a secured connection with security suite 1 and we filled the "Secured Connections" window with the following parameters:
Security : authenticationEncryption
System Title: 41 42 43 44 45 46 47 48
Block cipher key: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

Arduino ide gives an error when compiling the arduino code

Hello,
I need to read the actual power from P34S02 meter via RS485 with Arduino Mega.

I got this specification from utility company:
"Every 30 seconds at 19200 Bd meter of serial no.3400100688 in mode D sends data defined by the attached table."

Can anyone point me to the right direction, or provide an example ardino project for this?

Thanks

Hello
I have successfully made a dlms server using your GuruxDLMS.c arduino code on mega2560. Fortunately, HighGMAC is presented in your recent arduino release but unfortunately, the Invocation Counter object presented in this code returns no data so I cannot connect to the MDM or GuruxDLMSDirector with automatic read option of this counter. Would you please help me fix this problem?

Sincerely Yours

Hi,

Every 5 secs, we read 6 registers from dlms meter (from L&T). Occasionally we
get "Not enough memory available" error:

If I close connection, com port and open again, it works. And then error
repeats after some time.
I also made following change in the code:
con_initializeBuffers(connection, 50 + 1024);

Below logs show successful packets, followed by error packets and then
successful packets after reconnect.

Please let me know how to fix the issue.

Thanks and Best regards,
Prakash

hi,
I was using C guruxClient to read the data from multiple meters with multiple threads. i need to read the 100+ meter at the same time. but i was unable to connect to multiple meter at the same time (unable to initializeConnection).
can someone help me out.

Hello,

Currently i'm a student and working my final project assignment. my final project was creating my own kWH meter using DLMS protocol via TCP/IP and MQTT. i have reading this tutorial and i dont have any idea how to do that. this is my block diagram. i need help step by step how to do that

thank you very much

I am getting this error when running the client. From the log file it seems like there is two-way communication going on between my RPi and the Omnipower reader so I guess the port are connected correctly:

hello admin
i am about to embark on a smart energy meter project that works with arduino board, the basics of this project is to create a smart electricity meter using arduino and make sure it uses DLMS to establish communication, this project is centered around me understand everything about DLMS and how it works, now most of the resources i see online describe how to establish communication with arduino board using dlms, my question is this, arduino isn't a manufacturer of electricity meter and is a development board,
