WIZnet / Mbed 2 deprecated WizFi310_Legacy_DNS_TCP_HelloWorld

WizFi310 DNS TCP Helloworld library 2.0 version

Dependencies:   WizFi310Interface_Legacy mbed

Prerequisite

This example shows that Wizwiki-W7500 and WizFi310 connect to a DNS server and get a its ip address. And then, It connects to '4.ifcfg.me' that returns an ip addess as TCP client.

To implement this function, you need a Platform board and Wi-Fi board. Below are what we used.

  • WIZwiki-W7500 from WIZnet (Platform board)
  • WizFi310 from WIZnet (Wi-Fi board)

Hardware Configuration

WIZwiki-W7500 Pin map

pin map

  • D0 is for RXD, D1 is for TXD
  • D6 is for CTS, D7 is for RTS
  • D9 is for RESET

WizFi310 Pin map

pin map

  • J1 is for RXD, J3 is for TXD
  • SW6-1 is connected to D6 for RTS, SW6-2 is connected to D7 for CTS
  • SW5-3 is connected to D9 for RESET

Connect to Wi-Fi

wizfi310.connect(SECURE, SSID, PASS);

Get information

const char *ip = wizfi310.getIPAddress();
const char *mac = wizfi310.getMACAddress();

Access to a 'mbed.org' website and get its ip addess

Endpoint addr;
addr.set_address("mbed.org", 80);
printf("mbed.org resolved to: %s\r\n", addr.get_address());

Access to a '4.ifcfg.me' as a TCP client and get its ip addess

TCPSocketConnection socket;
socket.connect("4.ifcfg.me", 23);
 
char buffer[64];
int count = socket.receive(buffer, sizeof(buffer));
printf("public IP address is: %.15s\r\n", &buffer[15]);
