Long reading ends with "Invalid frame ..." error.

Forums

Gurux DLMS for ANSI C

Long seances (hundreds of HDLC packets) ended with "Invalid frame..." errors. Same readings in Director are OK. Different devices.

What can I check by myself?

how to limit frame size on client side?

Forums

Gurux DLMS for ANSI C

Strange device works in "Director" only if checkbox "use frame size" is checked in "device properties".

How to set same option in C library?
Or is there other way to limit frame size?

Get block transfer error

Gurux DLMS for ANSI C

Hello!

I have implemented a DLMS server on a Texas Instruments C2000 microcontroller, based on the ANSI C server examples. Communication is established over PLC, and I have already implemented serialization of the PRIME API on the C2000. The DLMS server interface I am using is TYPE_PDU.

Producing large size response packet on US Association

Forums

Gurux DLMS for ANSI C

Hi,

We are developing indian standard meter . In wrapper communication interface of US Association, existing gurux library is producing large size of response buffer when reading objects. Can you please suggest a suitable encoding mechanism to reduce the response buffer size when reading objects for less memory consumption.

Here is the below request-response .
