Description

Send a UDP packet to a network address identified by the remote IP address and remote IP port parameters.

Note

If you are having trouble using UDP to communicate with a computer, investigate whether antivirus or firewall software might be blocking UDP traffic. If so, try reconfiguring the software to allow UDP traffic for a specific IP port number.

Examples

Control LEGO MINDSTORMS EV3 Robot from Host Computer

Control LEGO MINDSTORMS EV3 Robot from Host Computer

Create a Simulink® model to communicate between the Host PC and the LEGO® MINDSTORMS® EV3 robot. The Simulink model running on the Host PC will exchange data with the EV3 brick and control the motion of the EV3 robot.

Parameters

Enter the address or hostname of the IP node on the remote device.

To broadcast the UDP message to all devices, use the default parameter value, '255.255.255.255'. Use this approach sparingly to avoid creating unnecessary broadcast traffic. Often, IP routers are configured to drop broadcast UDP packets sent to '255.255.255.255'.

The number of the IP port on the remote device, which can range from 1 to 65535. This value defaults to 25000.

Select this option to determine the local port source from which the block sends the data.

Enter the local port from which the block sends the data to the remote host.
