Examples for receive and send TCP packages

[martinmmi]

Hello, iam martin from germany and i like to develop a tcp interface for an esp32 application.

I have this tcp sequences from a incoming tcp server:

OFF: 80 30 41 42 43 44 45 46 47 20 20 20 20 20 20 20 20 20

GREEN: 80 31 41 42 43 44 45 46 47 20 20 20 20 20 20 20 20 20

RED: 80 33 41 42 43 44 45 46 47 20 20 20 20 20 20 20 20 20

How can I evaluate this sequences in a tcp client? Are some examples availble?

Many thanks Martin
