Hello,

i want to read the bytesavailable inside the serialport buffer every second. The bytes can vary, so i can't use a specific number of bytes to read.

Is there a possible solution for this task ?

Thanks.

Hi Kaan,

I understand that you need to read available bytes with a timeout of 1 second

To achieve this, you can use the ‘Timeout’ function of the ‘serialport’ object.

The below example reads 16 values of 'uint32' data in '1 second' from the 'COM3' serial port:

s = serialport("COM3",9600,"Timeout",1); 
data = read(s,16,"uint32"); 

You can loop over the above example to achieve your task.

Please refer to the following documentation for more information,

Hope this helps!
