Hello,
I have a project of implementing a HHU based on embedded system, which can communicate with energy meter through optical port using Mode A or C(IEC 62056-21). Can gurux provide protocol stack for this implementation? Or how should we use gurux libraries for this project?

Thank you

Hi,

Hi,

We are not supporting IEC 62056-21 anymore. Main reason why IEC 62056-21 is not supported is that implementation between device manufacturers varies a lot.
