Hello, I hope you are doing well. I want to send Table using UDP. How can i do that?
I have write the following code but it does not working. Can anyone help me with that
client_port = 10011;
clientAddress = '192.168.100.202';
% Define the table
C = {5 "cereal" 110 "C+"; 12 "pizza" 140 "B";...
23 "salmon" 367 "A"; 2 "cookies" 160 "D"};
T = cell2table(C, 'VariableNames', {'Age', 'FavoriteFood', 'Calories', 'NutritionGrade'});
% Open a UDP port
u2 = udpport("IPV4",'LocalPort',client_port);
% Send the data
write(u2, clientAddress, client_port, T);

Save yourself some work and add only tags that are actually related to your question, not 22 unrelated (like image processing) or useless tags such as matlab, matlab code, code, etc.

According to the documentation, the "data" input is:
"Vector of values to write, specified as a row (1-by-N) or column (N-by-1) array of numeric data, string, or character vector."
A table is none of those things.
Also, the order of the inputs is:
"write(u,data,destinationAddress,destinationPort)"
or
"write(u,data,datatype,destinationAddress,destinationPort)"

If the table contains numeric data, strings, and/or character vectors only, then you can write its contents in multiple write calls, where each call writes data only of one class, e.g., by writing one column of the table at a time.

for ii = 1:numel(C)
write(u2, C{ii}, class(C{ii}), clientAddress, client_port);
end
