In the past days i had some issues while i’m trying to read some Arduino datas using Matlab. I made a simple Matlab script which should read a number from Arduino but when I open the serial port after a while i get this error:
Warning:A timeout occurred before the Terminator was reached.
after some search on web i find that pressing reset button on Arduino board just after started Matlab script, it is able to read the data correctly. So, if you get the error shown above:
1) lunch Matlab script
2) press reset button on the Arduino board
3) you should be able to see the Tx led of Arduino blinking
Here there are 2 example of sampling. I was reading the output signal from a 433Mhz receiver.
