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:
Embedded Coder Support Package for ARM Cortex-A Processors

Description

Add-On Required: This feature requires the Embedded Coder Support Package for ARM Cortex-A Processors add-on.

The UDP Send block transmits user datagram protocol (UDP) data to a remote host.

Examples

Get Started with Embedded Coder Support Package for ARM Cortex-A Processors

Use Embedded Coder^® Support Package for ARM^® Cortex^®-A Processors to run a Simulink^® model on an ARM Cortex-A9 (QEMU) emulator.

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 | uint8 | uint16 | uint32 | Boolean

Parameters

To edit block parameters interactively, use the Property Inspector. From the Simulink Toolstrip, on the Simulation tab, in the Prepare gallery, select Property Inspector.

To set the block parameter value programmatically, use the set_param function.

To get the block parameter value programmatically, use the get_param function.

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, retain the default value '255.255.255.255'.

Programmatic Use

Block Parameter: remoteURL

Remote IP port — IP port of remote host

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

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

Programmatic Use

Block Parameter: remotePort

Local IP port source — Select local IP port source

Assign automatically (default) | Specify via dialog

To enable the system automatically assign the local IP port number from which data is sent, select Assign automatically. To specify the local IP port number using the Local IP port parameter, select Specify via dialog.

Programmatic Use

Block Parameter: localPortSource

Local IP port — IP port on local host

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

Specify the local IP port number of the application on the hardware board from which you want to send the data. The port number can must be an integer from 1 to 65,535. The default value, -1 assigns any randomly available port as the local IP port.

If the receiving host accepts UDP data from a particular port number, set this parameter to that number.

To enable this parameter, set Local IP port source to Specify via dialog.

Programmatic Use

Block Parameter: localPort
