  • NVIDIA UDP Send block

Libraries:
NVIDIA Jetson and NVIDIA DRIVE / Network

Description

Add-On Required: This feature requires the MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms add-on.

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.

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

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

Parameters
