Hi, I'm using netconn API. While testing lwIPv2.0.1, I found my device seems stuck after running for a couple minutes.
My device running lwIP (192.168.0.103) as a tcp client. A Linux laptop (192.168.0.104) running "netcat -l 8088" to receive data. In my use case, it's one-direction data transfer as lwIP device sending data to the linux server. After running for a couple minutes, I got a lot "TCP Spurious Retransmission and TCP Dup ACK", then the transfer stuck and abort in the end. I upload my wireshark logs to below link: (I capture the log twice, the same symptom) https://www.dropbox.com/sh/35pl7ogm37xdccq/AADJiUZRAcO5z8lmbU6oaKSna?dl=0 on log1, this issue begins from No. 44908. on log2, this issue begins from No. 19090. Appreciate if someone can take a look at this. Thanks, Axel _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
