Hi,
I looked up the code for upto 2012 and based on what I saw, the code for readBytes and timedRead are the same. What might however cause different behaviour is that readBytes
calls timedRead
n times for n bytes. Each timedRead makes a call to millis (which could be making the difference here).
Your code however waits for the all the bytes to be available in the serial buffer before reading all of them at once.
I haven't made any measurements on a DSO and can't verify this however. I don't even know if readBytes
is infact slower, let alone how much slower per byte(microseconds, milliseconds etc). Let me know if you find out more.

Hello,
Good question, I think this came from test a colleague did a while ago (already 5 years from now...)
But maybe it has changed or the test is not valid anymore. Feel free to replace that with the readBytes
, I would be happy to have a feeback/proper comparison ;).
