USBLAN USB-based local area network ( LAN) established between the Academic RIO and the PC host computer.

RT requires a network connection to at least one other host connecting the Academic RIO Device to the PC via the USB cable establishes the.

However, UDP works quite reliably within a local area network.

UDP is a connectionless protocol, meaning the transmitted datagrams are not guaranteed to arrive at their destination.

Stop parallel loops with the “notifier” technique.

Display all IP addresses known to the host.

Echo any received messages back to the sender.

Listen for messages on a user-defined port.

Read and display the returned messages, and indicate the IP address and port number of the sender.

Periodically repeat the transmission when enabled to do so.

Send the host name and system time as a message to a destination host designated by its IP address and port number.

Establish a connectionless communication channel between two Internet-connected hosts that requires minimal overhead compared to the higher level protocols.

HTTP HyperText Transport Protocol, the basis of the “world wide web” TCP Transmission Control Protocol, a connection-based means to send and receive data packets with guaranteed reliability

Exchange information with some types of Internet services that use the lower-level UDP protocol instead of.

> This is for update on site (by customer). This script will load a rootfs image from update partition of an eMMC splitted into 10M chunks that will be written to an other partition of the eMMC. U-Boot will load/source a script from an ext4 partition. As the board has no display/leds, the only way to get update progression is to broadcast UDP packet that a PC software will monitor. > I want to send the current progression of an update script. > there is a more appropriate way to solve the problem you have instead. > I'd like to understand the purpose / use-case for this command? Maybe So that means your invocation should be "nc -u -p Would require that switch (so TCP could be added later). In netcat, you specify a "-u" switch to enable UDP, so your command Best to make it something that does not collide with Pipe support in U-Boot's shell, the data to send will have to be a The same semantics as netcat as much as possible.
