UDP Receive

Receive UDP data from remote host

• Library:

• Simulink Support Package for Apple iOS Devices / Communication

• 

Description

The UDP Receive block receives user datagram protocol (UDP) data from a remote host. The block reads available UDP data from the socket buffer and outputs the data as a vector.

Ports

Output

Data — UDP data received

numeric vector

UDP data received from a remote host, returned as a numeric vector. Set the data type of this output by using the Data type parameter.

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

Size — Size of received UDP packet

nonegative scalar

Size of received UDP packet, returned as a nonnegative scalar. While the block waits for new data to arrive, this port outputs a 0. When new data arrives, this port value changes to the length of the received UDP packet.

Data Types: uint16

Parameters

Local IP port — IP port number of local device

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

Specify the IP port number of the local device. The local device is the iOS device that is running the model.

Data type — Data type of output UDP packet

uint8 (default) | uint16 | unit32 | int8 | int16 | int32 | single | double

Set the data type of the vector elements in the output. Match this data type with the data input used to create the UDP packets.

Data size (N) — Size of output UDP packet

255 (default) | positive integer

Specify the number of data elements in each UDP packet. Match the data size used to create the UDP packets.

Sample time — Sample time

0.01 (default) | nonnegative scalar

Specify how often this block reads the port buffer. Enter a value greater than zero.

Note

Smaller values for Sample time require the processor to complete the same number of instructions in less time, which can cause task overruns.
