UDP Send

Send UDP packets to UDP host

Since R2020b

Libraries:
NVIDIA Jetson and NVIDIA DRIVE / Network

Description

The UDP Send block sends UDP packets to a UDP host. Use the block for stateless and connectionless data transmission.

The IP address and the port number of the receiving host are specified in the Remote IP address (255.255.255.255 for broadcast) and Remote IP Port parameters.

The block accepts input with data type int8, uint8, int16, uint16, int32, uint32, single, or double.

Note

Your antivirus software or firewall might block UDP traffic. Configure the software to allow traffic from a specific IP port number.

Examples

Send and Receive Data over UDP on NVIDIA Jetson Platforms

Use MATLAB® Coder™ Support Package for NVIDIA® Jetson® and NVIDIA DRIVE® to send and receive UDP data over the network on a Jetson board.

Ports

Input

expand all

Port_1 — Input data port
vector

The port accepts an array and sends it as UDP packets over an IP network port to the receiving UDP host.

Parameters

expand all

Remote IP address ('255.255.255.255' for broadcast) — IP address of receiving UDP host
`'255.255.255.255'` (default) | `any valid IP address`

Specify the IP address or the host name to which the block sends the UDP packets. To broadcast packets to all the receiving hosts, specify '255.255.255.255'.

Remote IP port — IP port on receiving host to which data is sent
`25000` (default) | positive integer in the range [1,65535]

Specify the port number of the application on the receiving host to which you want to send the packets. Match the remote port number with the local port number of the receiving host.
