Arduino WiFiNINA - WiFiUDP.beginMulticast()用法及代碼示例

WiFiUDP.beginMulticast(IPAddressport, port);

…
WiFiUDP udp;
void setup() {
  Serial.begin(9600);
  while (!Serial) {
        ;
  }

  if (WiFi.status() == WL_NO_MODULE) {
        Serial.println("Communication with WiFi module failed!");

        while (true);
  }

  while (status != WL_CONNECTED) {
        Serial.print("Attempting to connect to SSID: ");
        Serial.println(ssid);
        status = WiFi.begin(ssid, pass);

        // wait 10 seconds for connection:
        delay(10000);
  }
  Serial.println("Connected to wifi");
  printWifiStatus();

  Serial.println("\nStarting connection to server...");

  udp.beginMulticast(IPAddress(226, 1, 1, 1), 4096);
  Serial.println("\n connected udp multicast");
