Hello, I just glanced at the code, but noticed that your remote_pcb is not bound to a local endpoint. I'm working on a project using the LWIP raw API with the stm32f2 and cannot get it to work. lwIP - lightweight TCP/IP lwIP is a light-weight implementation of the TCP/IP protocol suite that was originally written by Adam Dunkels at the Computer and Networks Architectures (CNA) lab of the Swedish Institute of Computer Science but now is being actively developed by a team of developers. The IP address can be specified as IP_ADDR_ANY in order to bind the connection to all local IP addresses. I can set-up my connection and close it, but then I have to wait a certain amount of time before binding/connecting on the same address+port according to: Only after some time (minutes) the resources are completely cleared in the underlying stack due to the need to follow the TCP specification and go through the TCP timewait state. Not sure why it did not (maybe because of the state the port is in). LwIP defines three types of pbufs, depending on the allocation type: Chains two pbufs together (but does not change the reference count of the tail pbuf chain). Use IP4_ADDR_ANY to bind to all local interfaces. Hi Guys! Im Using the AVNET LX150t Development Board, and I want to receive and send some UDP Packets. BSD-style socket API. 0 I have been searching for a stellaris port with lwip 1.
