Hello people,
i've got a project that includes meter, dlms hdlc protocol and esp. My esp needs to be like a server and when meter is connected to server, it sends data TX, and my server needs to receive that data and sends it back RX. So my ESP only receive and send thata from meter without processing data. I saw gurux arduino and it has Client and Server example. What example can i modified for the best results? Has anyone had experience with something similar to my project?
Thanks a lot forum!

Hi,
Sorry to say, but it's not that easy. If you are using HDLC framing, there is a CRC, frame counter, etc that caused the meter must process the data or the communication doesn't work. It's not that you just send static data and get static data back.
I believe this will help you to get started to implement the server:
