frdmk64f_lwip_tcpecho_bm

I have been working with frdmk64f_lwip_tcpecho_bm. It worked at first, then I changed the IP address and now I get:

C:\Users\Randy\Downloads\EchoTool-master\EchoTool-master\EchoTool\bin\Debug>ech
otool 192.168.1.129 /p tcp /r 7 /d hello

Hostname 192.168.1.129 resolved as 192.168.1.129

Can not connect to server

Statistics: Received=0, Corrupted=0

C:\Users\Randy\Downloads\EchoTool-master\EchoTool-master\EchoTool\bin\Debug>

Any ideas what I am doing wrong ?

Hi Randy:

If you change the echo server ip address, please make sure change your PC's ip address too to make sure they are in the same subnet.

I did a quick check on my side, it is OK.

Regards

Daniel

Well I started over with this. I deleted the my original example, I imported the example again, the ip address is 192.168.0.102 , the subnet mask is 192.168.0.102, and when I try to run the example I get:

C:\Users\Randy\Downloads\EchoTool-master\EchoTool-master\EchoTool\bin\Debug>echo
tool 192.168.0.102 /p tcp /r 7 /d hello

Hostname 192.168.0.102 resolved as 192.168.0.102

Can not connect to server

Statistics: Received=0, Corrupted=0

C:\Users\Randy\Downloads\EchoTool-master\EchoTool-master\EchoTool\bin\Debug>

Any ideas ?

Ahh. It was just a configuration error on my part on the host.

The one thing that still bugs me about this is that

the /d pattern "hello" in echotool never never displays

anything. Any ideas ?
