Hi Ezgi Ecevit, it can be understood from your query that you are trying to read data from mobile sensor through UDP or TCP/IP. I hope you will find the following codes useful to use TCP/IP to acquire the data.
You can do it in two ways:
Either you can use simply the MATLAB support package for android package to use the predefined functions and object to acquire different sensor data.
Or as you have mentioned you can use TCP/IP or UDP server to acquire the data as follows:
%Create TCP/IP object 't' Specify the server and corresponding port number.
t = tcpip("www.EXAMPLE_WEBSITE.com", 80);
%Set size of receiving buffer, if needed.
set(t, "InputBufferSize", 30000);
%Open connection to the server
fopen(t);
%Transmit data to the server(or a request for data from server)
fprintf(t, "GET /");
%Pause for the communication delay, if needed.
pause(1)
%Receive lines of data from server
while(get(t,'BytesAvailable')>0)
t.BytesAvailable
DataReceived=fscanf(t)
end
%Disconnect and clean up the server connection.
fclose(t);
delete(t);
clear t
If you wish to use UDP server you can define the object using, change the object declaration part as follows and use UDP object instead of TCP/IP object:
u = udp('localhost',<port>,'localport',<port>);
