Hi,

Our requirement is to design a product to have one to one UDP communication with a remote system. I tried to test the same with UDP echo example of Ti RTOS (udpEcho_EK_TM4C129EXL_TI_TivaTM4C129ENCPDT). I configure the IP settings in UDPEcho.cfg (Ti RTOS--> Products-->NDK--> Network Layer--> IP General settings. Set the IP address: 198.168.1.2 and IP Mask: 255.255.254.0 and gateway IP address: 0.0.0.0. Build the program and run in CCS. Console displayed " Network Added: If-1:192.168.1.2" Now run udpSendReceive 192.168.1.2 1000 1 -s100 from "C:\ti\tirtos_tivac_2_14_04_31\packages\examples\tools>" in command line,

I did not get any response.

Is it right what I am doing? Any other procedure? Appreciate help.

Regards,

Ramesh

What is the IP address on your laptop? What does the network look like (e.g. is there a router or you have the TM4C connected directly your laptop)?

Can you also use WireShark to see what is going to and from your laptop?

Hi Todd,

Laptop LAN IP addresss is 169.254.116.18. TM4C is directly connected with the laptop.

In wireshark I did not see any destination with 192.168.1.2". Attaching the wireshark logs.udpstat2.txt

Ramesh

Change your IP address on your laptop to 192.168.1.1 (the target is 192.168.1.2). Make sure your laptop is not connected to any other network (i.e. WiFi is turned off and there is only one Ethernet cable between the TM4C and the laptop).

Hi Todd,

Thanks for the help.
After changing the ip address to 192.168.1.1 It is working. How to change the port from 1000 to something else say 4000?

Change the define in ucpEchoHooks.c in the UDP Echo example as desired (and rebuilt/reload/run)

#define UDPPORT 1000

For the host-side tool, the first parameter in udpsendreceive.exe is the port number.
