Hello, I'm working on lwIP for sending data for raspberry device to windows server. I use config below:
#define MEM_SIZE (1 * 1024 * 1024) #define PBUF_POOL_SIZE (1024 * 4) #undef PBUF_POOL_BUFSIZE #define MEMP_NUM_TCP_PCB 128 #define MEMP_NUM_NETCONN 128 #define TCP_QUEUE_OOSEQ 1 #define TCP_MSS 1460 #define TCP_SND_BUF TCP_WND #define TCP_SND_QUEUELEN (4 * TCP_SND_BUF/TCP_MSS) #define TCP_WND 8 * TCP_MSS But send speed ~20 MB/s and after about 10-20 seconds, i can't send data any more and server send back many "dup ack" packets. Please suggest any good config for using tcp with lwIP. Regards, Sol
