acceleration function not working in script?

Hello, i'm trying to assign the value returned from the acceleration function in the mobiledev object

In the m variable I can see the acceleration values but when I call the acceleration function and assign its output to the variable 'x' nothing is in it.

When I run m.acceleration in the command window it works fine so why doesn't it work in this script?

Thanks

In general, the debugger shall be able to show you the reason. Just run your Untitle2.m using the matlab debugger, and put a breakpoint in line 5. Then you can examine m directly.

Yeah I can see that the m object contains the correct acceleration values but when I call the acceleration function on the m object it doesnt return anything which I cant understand.

I've been following this documentation: https://uk.mathworks.com/help/matlabmobile/ug/sensor-data-collection-with-matlab-mobile.html

Set a breakpoint at line 5, and when the debugger pauses there, copy line 5 and paste to the command line window. What do you get for x from the command line window?

Im using a waitfor function which works , why do I need to use this in a script but yet in command window I can call the acceleration function and the values are returned with no problem?

Oh, a time delay? The command line window somehow is slower than the function call? Where do you put the waitfor function?
