Hello , I'm working with W5500 as Client , I know in client mode w5500 should send Connect command and then send/receive data and then disconnect socket , Our Server is PLC and we want to read some data from PLC, My problem is sometimes w5500 doesn't receive SYN/ACK packet from server side then we can't connect to PLC and sometimes got it ! 75% of our test are successful connection but sometimes we have problem, what should I do for this problem ? In w5500 datasheet page 46 -> Connect partition -> number 2 , the reason of connection fail are explained, but my another question is if we have error in connection, what should programmer do to handle it ? should I send Connect command again ??
