Android Sensor support from MATLAB

by

 

31 Jul 2013 (Updated )

Use MATLAB to acquire sensor data from built-in sensors on your Android device.

File Information
Description

This submission enables MATLAB to access onboard sensors on Android mobile devices. With this submission, you can access a mobile device’s accelerometer, magnetometer, location, orientation and compass information directly from MATLAB running on your computer. You can access current and logged sensor data, and you can use MATLAB to visualize and analyze the mobile sensor data or make decisions based on the acquired data.

To use this submission, the computer and mobile device must be on the same network. The submission includes the necessary MATLAB files and a read me document for initial setup.
In order to use this support, you must first install the “Sensor UDP” mobile app available from Google Play.

The mobile app needs work. Hate to have to enter all the settings every time I restart the app. Don't like the "send" option. It should just echo at a user defined interval.

The .m program worked once out of the 3 attempts.

Hi Deborah,

Which mobile phone and version of MATLAB are you using? Having this information might be helpful in figuring our the root cause of the erroneous behavior.

A couple of things to check:

1. Are the computer and mobile device on the same Wifi network?
2. Does the Mobile Sensor Explorer app show any data for any of the sensors?

Neat. Works without any further ado.

28 Aug 2014 Stefan

Works out of the box!

Mobile App not very handsome.

For those who have problems:

Check your home folder and firewall!

Can't get it to work at all. Tried the mobile setup first as instructed, and got the error messages as above. Finally managed to fix that, ran mobile setup successfully, but still can't get Matlab to see any data. Am getting error message: Error using CapturingAzimuthRollPitchExample (line 35)
No data received. Type "help sensorgroup" for help diagnosing the problem.
I have tried this on two separate wireless networks now (home and work). If I could get this to work it would be really awesome for my research and I would up my rating accordingly.

Muy buena!

muchas gracias, muy buena programación...

Hello!

thanks for your code. I have a problem:
"No data received."

My host computer is also connected to network through WiFi, is there problem for the mobile phone to transmit the data?

08 Mar 2014 Greg

No GPS transmitted from Galaxy S II. All other sensors rcv good. GPS enabled under Location Services. Any ideas on what's preventing GPS transmission?

Working awesome.

I get these problems when I try to install it on R2013b on Wnd7 64bit. I added the folder and subfolders to the path.

Warning: Installation failed.
Error using matlab.apputil.install (line 38)
The specified file 'Mobile Sensor Explorer.mlappinstall' could not be found.

Error in setupmobile (line 37)
matlab.apputil.install('Mobile Sensor Explorer.mlappinstall');

Works perfectly. examples have some issues, but the main functions are good. Exactly what I needed.

13 Jan 2014 MathWorks Mobile Sensor Connectivity Team

As stated in the header of The GPS example file, Mapping Toolbox (which includes geopquadpt) is required for that example to be fully functional. The other examples included in the submission do not require Mapping Toolbox.

13 Jan 2014 Juyeong

I tried to follow the example(Capturing and Mapping GPS Example) and failed to run the line

[latlim, lonlim] = geoquadpt(lat, lon);

with error message
"Undefined function 'geoquadpt' for input arguments of type 'double'."

am I missing the function 'geoquadpt' in my path? or other problems?

This submission will only work on R2013a and R2013b.

08 Jan 2014 Prashnna Gyawali

Isn't there any possibility of using this submission on the older version of MATLAB like R2011a??

05 Jan 2014 Emad

Same problem as "danushka bandara": when I run setupmobile on 64 bit Matlab 2013a
The specified file 'Mobile Sensor Explorer.mlappinstall' could not be
found.

Any chance you could add an option for turning off logging? I have no need for it (I do it myself when I need to), and I dislike having to periodically empty it because it's growing so large.

Works in France on Android HTC One X device after setting language to English. No Position/Altitude, though. Please provide a Simulink block! thanks.

We have identified a bug when using Android devices configured with European settings. In this scenario, MATLAB will not receive data, and the connection will time out. We are working on a fix, but as a workaround, set your device to “US English” while using the SensorUDP app.

The most recent update on 8/26 includes a minor change to one of the examples (azimuth, pitch, roll) included in the submission. It was changed to make the sample code more readable. If you already were using the prior version, it is not necessary to download this update.

15 Aug 2013 Misha

This submission will work ONLY on 13a.

15 Aug 2013 hammad

would this submission run only on 2013a version or may be compatible with older versions also?

09 Aug 2013 Mark Jones

Hi Marc, David, and Chethan,

Can you tell us the full path to where you have unzipped the package to? For example, where does mobilesensormlconverter.dll curently reside?

Also, just to be sure, you did run setupmobile.m first, correct?

Please let us know at:

http://www.mathworks.com/matlabcentral/fileexchange/authors/contact/331522

Let's see if we can't figure out what is going on here and improve your experience!

Thanks!
Mark

09 Aug 2013 Chethan C U

Yup... same error here..
C:\......sensorgroup\sensorgroup\+matlab\+mobilesensor\+internal\..\..\..\private\win64\mobilesensormlconverter.dll.

Same problem as Marc:
Failure to load the requested plugin:
C:\......sensorgroup\sensorgroup\+matlab\+mobilesensor\+internal\..\..\..\private\win64\mobilesensormlconverter.dll.

I can't add the private folder to the path.

06 Aug 2013 Marc

I've followed the instructions and received the following error:
Warning: The following error was caught while executing
'matlab.mobilesensor.internal.MobileSensorController' class destructor:
Attempt to reference field of non-structure array.
> In sensorgroup>sensorgroup.sensorgroup at 395
Failure to load the requested plugin: C:\...\private\win64\mobilesensormlconverter.dll

But the file does exist and I am in the correct directory. Any advice?
