BlueSmirf: Bluetooth Notes - How I got data passthrough working
Reference Doc: https://cdn.sparkfun.com/assets/1/e/e/5/d/5217b297757b7fd3748b4567.pdf
Initial Setup Doc: https://learn.sparkfun.com/tutorials/using-the-bluesmirf#example-code-using-command-mode
Final Setup: (Data Passthrough settings)
$$$ Type this within 60 sec of turning modem on. You get a "CMD" response.
+ This turns on echo so you see what you are typing.
SU,96 This sets 9600 baud to Uno.
ST,255 This disables that pesky 60 sec timer.
--- This ends the command session.
