Hi,

I came across your code for A1140 meter driver written in C#, I would like to request if possible to provide a C or C++ version that can run on a micro controller instead of a PC.

Hi,

I will try when I have time.

Can you share the communication protocol document you've used to write your code? I can do a C/C++ implementation.

I used IEC 62056-21 protocol https://community.openenergymonitor.org/uploads/short-url/jEAlRGXemWuRmgMiMOIcfSekFcM.pdf

Thank you, Will go through it and reachout if I enocunter issues. One question, the encryption key you've used is standard for all Elster meter?
