You've reached the support tracker for Savannah, the software forge.  However, it looks like your request is about some package that may be hosted here (I can't tell what that package is).

Please use the appropriate tracker.

Hello,

I am trying to implement a TCP client on a XMC4800. This client should be able to send individual messages to a Server and to receive the response messages.
For the beginning, I worked with the "IOT_EXAMPLE_XMC47" from Infineon and implemented this example for a XMC4800. This example useses LwIP. Also, I removed some functions which I don't need for the communication. I have this source code so far:
see: main.c

I use Wireshark to analyze the network communication between the XMC and my PC. But the TCP connection always resets and I don't know why. Maybe because my PC is not working for a host?

I also tried to connect the XMC with Putty (RAW Connection type), but that doesn't work either. Besides, I do get a ping response form the XMC.

PS: I hope you can open the zip attachment wich includes the project.

Thank you for your help!
Regards,
Maxi
