I try to develop a code to acquire data from sensors. I want to use Matlab Mobile App. My question is that is possibile to acquire Data until (while cycle) I press "STOP" button in app. I try whit this code, but it dosen't work
clear all
close all
clc
m = mobiledev;
m.AccelerationSensorEnabled = 1;
m.AngularVelocitySensorEnabled = 1;
m.Logging = true;
while m.Logging
[a,~] = accellog(m);
[ang,~] = angvellog(m);
end

Lorenzo - I haven't used the mobiledev app before, but some GUIs that are designed in a similar manner with a "tight" while loop (i.e. a loop that is not interruptible) require that you add a short pause to the code. Try updating your code as
while m.Logging
[a,~] = accellog(m);
[ang,~] = angvellog(m);
pause(0.001);
end
to see if that helps.

while m.Logging
[a,~] = accellog(m);
[ang,~] = angvellog(m);
pause(0.001);
end
then this seems to fix the problem.
