Summary: TCP Connection with LwIP Project: Savannah Administration Submitted by: None Submitted on: Wed 09 Jun 2021 06:14:27 AM UTC Category: None Priority: 5 - Normal Severity: 3 - Normal Status: None Assigned to: None Originator Email: sakskiamaxi.b...@draeger.com Operating System: None Open/Closed: Open Discussion Lock: Any _______________________________________________________ Details: 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!
