Run Model on Android Device

Step 4 of 5 in Log Signals in MAT-Files on an Android Device

To deploy the Simulink^® model on the Android^® device, on the Hardware tab of the Simulink model, in the Mode section, select Run on board, and then click Build, Deploy & Start. The lower left corner of the model window displays status while Simulink prepares, and downloads the application on the device.

The application starts running and logs signals in MAT-files on the device. The files are named as <modelname>_<runnumber>_<indexnumber>.mat. The name of your Simulink model is modelname. runnumber is the number of times the model is run. runnumber starts with 1 and is incremented by one for every successive run. indexnumber is the MAT-file number in a run. indexnumber starts with 1 and is incremented by one for every new file that is created in the same run.

Suppose that the name of the model is androidMatFile. In the first run, Simulink creates androidMatFile_1_1.mat file and starts logging data in this file. After the logging in the first file is completed, Simulink creates androidMatFile_1_2.mat file and continues logging data in this file. Likewise, the logging continues in multiple MAT-files until the Simulation stop time is elapsed. If the same model is run again, the new files are named as androidMatFile_2_1.mat, androidMatfile_2_2.mat, and so on.

After the Simulation stop time elapses, the logging of signal stops.

Note

Data loss occurs when:

The total file size exceeds the available device storage capacity.
The signal logging rate is faster than the device writing speed.
