MATLAB: UDP in matlab

data transfer in matlabguiInstrument Control ToolboxMATLABudp

Hi , I'm working on a project in matlab

I have a matlab GUI on one computer and I want to send a word indicating which button on the GUI has been clicked to the other computer using UDP where the 2nd computer can execute specific function later on according to the button clicked ,

my problem is that I can only click one button that the computer on the other side will receive its data & then I have to re run the server side again to revive the 2nd button clicked .. my UDP connection on the server side will end just accepts one data

how can I make it accepts more the one until I end it my self ?

here what I'm doing :

PC 1

u1 = udp('192.168.1.2', 'RemotePort', 8866, 'LocalPort', 8844) fopen(u1) fprintf(u1,'counter clk wise') fclose(u1) delete(u1) clear u1

This will be repeated with every button I couldn't make it general in the GUI

& here my server PC2 :

u2 = udp('192.168.1.2', 'RemotePort', 8844, 'LocalPort', 8866) fopen(u2) % open the host 2 pause(1) fscanf(u2) % print data from host 1 % close : %fclose(u2)

I've read several topics but no luck … can any one help me with this a hint maybe

thnx

Best Answer

To receive multiple messages, you need to put a loop in the PC2 code. Something like this:

u2 = udp('192.168.1.2', 'RemotePort', 8844, 'LocalPort', 8866)
fopen(u2) % open the host 2 
while ~<insert some stopping condition here>
pause(1)
fscanf(u2) % print data from host 1 
end
fclose(u2)

MATLAB: How to receive UDP broadcast data in MATLAB using Instrument Control Toolbox

You can receive UDP broadcast data using the UDP functionality in Instrument Control Toolbox.

If you are only receiving UDP packets, and not sending out any UDP packets, the only relevant properties of the UDP object are LocalHost and LocalPort; the RemoteHost and RemotePort are not relevant in this case.

LocalHost is the host name or IP address of the Ethernet adapter you are receiving the UDP packets on, and the LocalPort is the port number you are receiving the UDP packets on.

Note: If you don't specify LocalHost (or if you set it to an empty string), you will receive UDP packets on all available Ethernet interfaces at the specified LocalPort.

% Listen on all available Ethernet interfaces at local port 8000.
% Specify a LocalHost (host name or IP address) if known
u = udp('', 'LocalHost', '', 'LocalPort', 8000);
fopen(u);
% Receive a single UDP packet
packetData = fread(u);
% Clean up
fclose(u);
delete(u);
clear u

MATLAB: What IP address should I use with xPC Target to connect the host and target computers using a TCP/IP crossover cable

To begin, use an unshielded twisted pair (UTP) cross-over cable with RJ45 connectors for direct connection between the host and target computers, and then use the following steps:

1) Enter the following command at the MATLAB command prompt on the host computer:

!ipconfig

2) Assign the target computer IP address to be 1 above the host PC IP address. For example, if IPCONFIG returns the IP address of "192.168.1.100", then enter an IP address of "192.168.1.101" for your target computer in the XPCSETUP GUI.
