W5500 Client is not connect

Question

First of all, hello, I am working on W5500. I use it comfortably as a server. But when I use it as a Client, I have a problem on the ‘connect’ side. I think there is a problem with the Mac address. I am sharing Wireshark listening as a screenshot. W5500 ; MAC=0x8C,0x1F,0x64,0xB0,0x80,0x01 192.168.1.66 255.255.255.0 192.168.1.1 8.8.8.8 port=500; The IP address you want to connect to is 192.168.1.243 my connect code; if((Baglan!=SOCK_OK) ){ Baglan=connect(1,serverIp,500]); } if(getSn_SR(1)!=SOCK_ESTABLISHED ){ socket(1,Sn_MR_TCP,500,SF_TCP_NODELAY); Baglan=0; } dasda1095×231 9.41 KB

You seem to use 255.255.255.0 for server IP address. And check if connect is blocking and you should not do anything else after it returns (e.g. wait for status register transitions, and not just check for establish state once). I am also not sure where do you close the socket before you reopen it.

Thanks for answer. Yes, i noticed too. During my work, when I set the IP address of the w5500 chip to 192.168.1.55, the connection was made. But when I change the IP address, I cannot connect. You said my connection might be blocked. How can I check this? Kind regards,
