Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 2, Size: 0

I think this means the data is not actually being read, since the buffer is empty.

Everything worked perfectly once, then next time I tried, with no cone changes, it stopped.

public static void main(String[] args) throws IOException, InterruptedException {
    SerialPort serialPort = new SerialPort("/dev/rfcomm0");
    try {
        serialPort.openPort();

        SerialInputStream is = new SerialInputStream(serialPort);
        SerialOutputStream os = new SerialOutputStream(serialPort);

        new EchoOffObdCommand().run(is, os);
        new LineFeedOffObdCommand().run(is, os);
        new TimeoutObdCommand(100).run(is, os);
        new SelectProtocolObdCommand(ObdProtocols.AUTO).run(is, os);
        ThrottlePositionObdCommand tps = new ThrottlePositionObdCommand();
        tps.run(is, os);
        System.out.println(tps.getPercentage());        

    }
    catch (SerialPortException ex) {
        System.out.println(ex);
    }

}
