udp receive

Listens on a UDP port and emits one message per datagram received.

Properties

• port — local port to listen on (1–65535).
• poll interval (ms) — internal receive polling cadence. Default 20ms; rarely needs changing.

Behavior

Uses the flow's WiFi network (its WiFi field, shared by every WiFi node). The payload is the raw bytes received, unparsed — decode it yourself in a function node if you're expecting text or a structured format. host and port fields on the message carry the sender's address, alongside the payload.
