RT networking: User Datagram Protocol (UDP)
UDP is a simple and efficient connectionless IP networking protocol used between LabVIEW applications as well as other IoT devices.
Summary
UDPUser Datagram Protocol, a connectionless protocol based on sending data packets known as datagrams, a word play on “data” and “telegrams” is a simple, efficient, and connectionless IPInternet Protocol describes the fundamental mechanisms for transferring information in the form of data packets protocol.
Code examples
UDP sender/receiver – Send UDP messages to a destination IP address and port number, listen for incoming UDP messages on a user-defined port, and echo received messages back to the source.
UDP client-server – Create a server on the Academic RIO Device that listens for UDP datagram messages from a client running on the PC host, accepts client information including the desired state of the four onboard LEDs, sets the LEDs accordingly, and returns the state of the onboard 3-axis accelerometer and pushbutton.
