I have two laptops, Laptop1 is where the arduino is connected to (with a transmitter), and Laptop2 is where the receiver is, thus, the wireless connection.
I would like to send a character or string from arduino(Laptop1) to matlab(Laptop2). Please note I am using a transmitter and receiver for this.
The receiver is connected in my COM10. Is this the right code for decoding the string sent by Arduino? Or are there things I need to change, because I keep getting an error message that says " Warning: Unsuccessful read: A timeout occurred before the Terminator was reached. "
global a;
a = serial('COM10','BaudRate',9600); %create serial communicationobject on port COM10
fopen(a);
meas = fscanf(a)

Check for any bytes stored in the buffer with the BytesAvailable option:
a = serial('COM10','BaudRate',9600);
fopen(a);
if a.BytesAvailable
meas = fscanf(a);
end
This way you only read when there is something to be read. Make sure the sender and receiver have the same configuration
