WizFi310_DNS_TCP_HelloWorld edited with a new Interface
Dependencies: NetworkSocketAPI WizFi310Interface 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
- D0 is for RXD, D1 is for TXD
- D6 is for CTS, D7 is for RTS
- D9 is for RESET
WizFi310 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
wifi.connect(AP_SSID, AP_PASSWORD, AP_SECURITY);
Get information
const char *ip = wifi.get_ip_address(); const char *mac = wifi.get_mac_address();
Access to a 'mbed.org' website and get its ip addess
SocketAddress addr(&wifi, "mbed.org", 80); printf("mbed.org resolved to: %s\r\n", addr.get_ip_address());
Access to a '4.ifcfg.me' as a TCP client and get its ip addess
TCPSocket socket(&wifi); socket.connect("4.ifcfg.me", 23); char buffer[64]; int count = socket.recv(buffer, sizeof buffer); printf("public IP address is: %.15s\r\n", &buffer[15]);
