UDP Send

Send UDP packets over IP network

• 

Libraries:
Raspberry Pi Blockset / Network

Description

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

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

Note

To generate code C/C++ code for this block, you must have an Embedded Coder^® license.

Ports

Input

Port_1 — Input data

vector

The block 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

Remote IP address ('255.255.255.255' for broadcast) —

'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.
