NDKTCPIP: Send.exe test utility stalls

Hello,

I am trying to communicate with my custom board that is running the enet_tcpecho_server_tirtos NDK example program. I want to use the send executable in the winapps folder to figure out the communication speed/bandwidth. However, I am running into an issue when I run the send executable, where it stalls on the 25th send (see screenshot below). What is the most likely issue here? I tried increasing the max heap size on my target application, as well as increasing buffer size in the example program, but to no avail.

Hello,

I am using a custom board with the TM4C1294NCZAD.

After adjusting the TCP buffer size on my PC and on my board the program doesn't stall, but now becomes extremely slow (the first couple "sends" are fast and say "passed," but after that it also lists the speed, which becomes slower and slower).

I assume the speed decrease has something to do with the TCP buffer filling up and not being able to handle the bandwidth, but I would be interested in hearing your take as well.

Otherwise, I think my main issue of stalling has been solved.

Thanks.
