Unable to stop Arduino Bluetooth data pulling

Hi, I would like to pull information from the arduino through bluetooth and be able to stop the data when a figure is closed. However, once I close the figure the code continues to run, I'm even unable to Ctrl+C in the command and the only way to stop the program is to close matlab.

Any ideas? Thank you

clear
clc
%fclose(instrfind)

%Open Serial COM Port
s = Bluetooth('RNBT-AD09',1);
fopen(s);
fid = fopen( 'Arduino.txt', 'w' );

g = figure;

pause(.5)

while ishandle(g) %Loop when Plot is Active

      dat = fscanf(s) 

      fprintf(fid, '%s\r\n', dat);

end

fclose(fid);
fclose(instrfind);

Solved the problem by having a pause in the loop

while ishandle(g) %Loop when Plot is Active

        dat = fscanf(s) 

        fprintf(fid, '%s\r\n', dat);

        pause(.1)

end
