You are using wrong pcb. On the server you start with a listening pcb. When your accept callback is called, it's passed a *new* pcb, that represents the established connection. You should use that pcb for tcp_write. Writing from receive callback works because in the receive callback the pcb argument is that connection pcb, not the original listening pcb. -uwe _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
