Byte Transmission Using UDP
Send and receive UDP packets using the dsp.UDPSender
and dsp.UDPReceiver
System objects. Calculate the number of bytes successfully transmitted.
Set the RemoteIPPort
of UDP sender and the LocalIPPort
of the UDP receiver to 31000
. Set the length of the data vector to 128
samples, which is less than the value of the MaximumMessageLength
property of the receiver. To prevent the loss of packets, call the setup
method on the receiver object before the first call to the object algorithm.
udpr = dsp.UDPReceiver('LocalIPPort',31000); udps = dsp.UDPSender('RemoteIPPort',31000); setup(udpr); bytesSent = 0; bytesReceived = 0; dataLength = 128;
In each loop of iteration, send and receive a packet of data. At the end of the loop, use the fprintf
function to print the number of bytes sent by the sender and the number of bytes received by the receiver.
for k = 1:20 dataSent = uint8(255*rand(1,dataLength)); bytesSent = bytesSent + dataLength; udps(dataSent); dataReceived = []; while (isempty(dataReceived)) dataReceived = udpr(); end bytesReceived = bytesReceived + length(dataReceived); end release(udps); release(udpr); fprintf('Bytes sent: %d\n', bytesSent);
Bytes sent: 2560
fprintf('Bytes received: %d\n', bytesReceived);
Bytes received: 2560
