Hi, I am working on the code which connects to a simple server,but when I use netconn_connect function to connect with the server,netconn_connect function returns '-5' value that is 'ERR_ABRT'. I am using LWIP 1.3.2 on FreeRTOS . For debugging, I'm printing debug information,my device keeps re-transmitting SYN three times.That is client sends an SYN,but the server doesn't send back ACK-SYN.To be honest I am not getting the idea with the netconn_connect () callback,What should I look at? Am I doing something wrong?
