UDP Message Received

The UDP trigger relays UDP messages. UDP is a simple datagram protocol that sends and receives data through specific UDP ports. Many sensor devices and mobile apps use UDP to publish live data. The data delivery is not guaranteed.

Note: The UDP trigger is not supported in a fault tolerant installation of FME Server.

Specifying UDP Ports

UDP ports cannot be duplicated across UDP triggers. There must be a unique UDP port for each UDP trigger.

When specific ports are desired, the port should be made available and not blocked by firewall settings. In the following example, Amazon Web Services firewall security settings are configured for an instance to reserve ports 5000 - 6000 (incoming) for the UDP trigger:
