Can somebody explain to me the differences between using the hardware serial option vs. the software serial option? The tutorials from the Wiki only use the software serial port. I am wondering if there are any advantages or disadvantages to using either of them.
Why if the default baud rate is 38400, do the examples in the Wiki monitor the serial port at 9600 baud? I got the shield set up and connected to my PC and it is definitely running at 9600 baud, and not 38400. So what is the command:
actually doing, since it doesn’t seem to be setting the baud rate to 38400. How do I raise the baud rate to 115200, since the “blueToothSerial.begin” command does not seem to set the baud rate.
