TCP : TX AND RX A SINGLE CHARACTER

Daniel Abad

Intellectual 330 points

I need "receive" and "send" a single character over TCP.

The PC sends a character to my "TM4C129XDevKit" and my "TM4C129XDevKit" respond with the same character to my PC.

Can you help me ?

Thank you in advance

Hello Daniel

Though it is a little overkill, but the software associated with the following reference design does that. It exchanges a number with the PC.

Have you seen The TCP Echo example showing how to use TCP sockets?

Hi Amit,

Thank you very much for your help.

But, your example is very complex for me.......

What I need is to convert my "MODBUS SLAVE RTU RS232" that runs very well , to TCP/IP.

Best Regards

Daniel Abad

I think you got something wrong. Modbus TCP is NOT just Modbus RTU via TCP/IP. I strongly suggest to download,read and compare the specifications.

But, your example is very complex for me.......

And I strongly suggest to start with something less complex. I had been working with implementations for both. Thus, if the presented example already troubles your, then you are in for some very frustrating experiences.

Maybe this reference design will be more useful - 32-bit ARM® Cortex™-M4F MCU based Small form factor Serial-to-Ethernet Converter

From a quick look it contains a Modbus /IP TCP Bridge.
