The function terminates if it times out (see eout () ). That code doesn't even compile. Not particularly memory/speed efficient, because it creates a byte array on each read, but it's easier to use than readBytes (byte b []) (see below). If you use interrupts with attachInterrupt, or a library that uses interrupts, the "Interrupt Service Routine" will be defined and called "outside of the loop () context. 15:58. So as long as there is no serial event, it relentlessly cycles through those drawing exercises.
The Bluetooth device's … The serialEvent() function is executed within each execution of your loop() function if there is data available, so it would be something like: while (true) { loop(); … The serialEvent method of SerialPortEventListener will be called with a SerialEvent object describing the event.
