Open the WiFi Web Server example. “File” -> “Examples” -> “AmebaWiFi” -> “WiFiUdpSendReceiveString”
Modify the highlighted code section (ssid, password, keyindex) to connect to your WiFi network.
Upload and Execution
Compile the code and upload it to Ameba. After pressing the Reset button, Ameba connects to WiFi and starts the UDP server with port 2390. After the UDP server starts service, Ameba prints the “Starting connection to server” message and waits for client connection.
As to the UDP client, we use “sokit” program in the computer to connect to UDP server.
Choose client mode and fill in the IP of UDP server (which is the IP of Ameba) and port 2390, then click “UDP Connect”.
After the connection is established, fill in “Hello World” in the Buf 0 field in sokit and click “Send”. Then you can see the Ameba UDP server replies “acknowledged”.
Refer to the Arduino tutorial for detailed information about this example.
