UDP Send

R2026b

Send data over UDP network to remote host

• 

UDP Send block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink Support Package for Android Devices / Communication
Simulink Coder Support Package for BeagleBone Blue Hardware / Communication
Simulink Support Package for LEGO MINDSTORMS EV3 Hardware

Description

Add-On Required: This feature requires the Simulink Support Package for Android Devices add-on.

Use the UDP Send block to send user datagram protocol (UDP) data to a remote host.

Note

If you are having trouble using UDP to communicate between your host computer and your Android^® device, antivirus or firewall software might be blocking UDP traffic. In this case, reconfigure the software to enable UDP traffic for a specific IP port number.

Ports

Input

Port_1 — Input data signal

numeric vector

Input data signal, specified as a numeric vector. The block sends this data as UDP data to the remote IP address at the remote IP port.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32

Parameters

Remote IP address ('255.255.255.255' for broadcast) — IP address of remote host

'255.255.255.255' (default) | valid IP address

Specify the IP address of the remote host to which you want to send UDP data. To broadcast the UDP message, use the default value, '255.255.255.255'. Use the default IP address sparingly to avoid creating unnecessary broadcast traffic on your network. Often, IP routers are configured to drop broadcast UDP packets sent to this default IP address.

Remote IP port — IP port number of remote host

25000 (default) | integer from 1 to 65,535

Specify the IP port number of the remote host to which you want to send UDP data. The IP port number must be an integer from 1 to 65,535.

Programmatic Use: Add Block

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