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) — how often the node checks for datagrams. Default 20.
• WiFi — the flow's WiFi network, shared by every WiFi node in the flow.

Wiring

Output — one message per datagram:

• payload — the raw bytes received, not parsed. To read text or a structured format, decode it in a function node.
• host and port — the sender's address.
