That's a neat little app. If you have the Instrument Control Toolbox, you could probably use the UDP object to get the information that you need.
I don't have that software, so went to the File Exchange and grabbed the Simple UDP Communications App code. It is just one function, judp, that allows you to send and receive UDP packets.
Assuming that the Wireless IMU app is running and that I just want to get the next 100 packets, then the following code would do the trick
% target port as set in the app
port = 5555;
payloadData = cell(100,1);
for k=1:100
% get the message/payload only assuming a max size of 200 bytes
[msg,~] = judp('RECEIVE',port,200);
% save the payload to the array
payloadData{k} = msg;
% convert the message to ASCII and print it out
fprintf('%s\n',char(msg)');
end
Some sample payload data was
1406156316.20970, 3, 0.157, 0.333, 9.850, 4, -0.000, 0.001, -0.000, 5,
14.699,-0.420,-49.500
1406156316.27678, 3, 0.271, 0.287, 9.832
1406156316.34447, 3, 0.199, 0.281, 9.844
1406156316.41106, 3, 0.201, 0.286, 9.844, 4, -0.001, 0.001, 0.001, 5,
14.699,-0.479,-49.680
1406156316.47826, 3, 0.242, 0.319, 9.856
1406156316.54561, 3, 0.208, 0.283, 9.861
1406156316.61258, 3, 0.216, 0.250, 9.862, 4, 0.000, 0.000, -0.000, 5,
14.699,-0.420,-49.860
As described in the Wireless IMU app, a comma separated list of data is sent in the UDP payload. I found that the payload sizes were either 44 bytes or 100 bytes. The smaller payloads contained a timestamp and the accelerometer data only, whereas the larger messages had the timestamp, accelerometer, gyroscope and magnetometer data. Two of the former appeared for one of the latter at the Slow (Normal) update rate.
All data seemed to match that which was displayed in the app on my phone.
Try the above and see what happens!
