Description

Add-On Required: This feature requires the Simulink Coder Support Package for BeagleBone Blue Hardware add-on.

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.

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.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"androidcommunicationlib/UDP Send"

Example: add_block("legoev3lib/UDP Send","myModel/myBlock",MakeNameUnique="on")
