MatLab connection to Arduino using Bluetooth

Question

I am attempting to send some information from MatLab to an Arduino Uno via Bluetooth with the following

MatLab program:

b=Bluetooth('HC-06',1);
fopen(b);
for i=1:1:15 
 fprintf(b,i); 
 out(i) = fscanf(b,'%d');
end
fclose(b)

and Arduino program

int matlabval=0;
void setup() {
 Serial.begin(9600); 
}
void loop() {
 if (Serial.available() > 0) {
 matlabval = Serial.read();
 Serial.println(matlabval); 
 }
}

the output of arduino is

1 10 2 10 3 10 4 10 5 10 6 10 7 10 8 10 9 10 10 10 11 10 12 10 13 10 14 10 15 10

The number 10 appears after each number. Why is that so?

Thanks in advance!

• aaa: asciitable.com Decimal 10 is the ASCII code for a "New Line" so it appears your Matlab send code will add a "New-line" after each sent value.

Answer 1

As discussed in the comments, the "problem" seemed to be Matlab adding a "New Line" which is a decimal 10 in ASCII.
