Not sure if sending serial data

I am trying to send serial data to my arduino, I am not sure if it is receiving it. This is what my code looks like.

clc
clear s

s = serialport("COM4",115200);
text = extractFileText("transition.txt");
write(s,text,"string");

Is there way that I can check to see if the arduino is actually getting the string?

Hii,

You can use writeline and readline functions write and read back from aurdino.Alternatively,you can use readDigitalPin and writeDigitalPin functions to check if serial communication is established between aurdino and MATLAB.Refer to below links for further information.

writeline

readline

writeDigitalPin

readDigitalPin
