I was wondering if anyone has tried using a bluetooth serial adapter on the Smoothie Board? I have both the Adafruit board based on the nrf8001 chip that communicates over SPI and a TinySine which is a cheap UART > bluetooth 4.0 adapter.
I'd like to get one hooked up to my Smoothieboard with the intention that I'd be able to have some GCode on the SD card and have the bluetooth start / stop things from an iPad.
Couple of questions relating to that…
Where are the SPI pins on the smoothie board and does the firmware receive commands over SPI like it does the UART?
This may seem like a stupid question, but just to make sure… the UART connection is the one next to the usb connector labeled "Serial" and it has 6 pins but only four are labeled… TX/RX/ V+ and GND, correct? Simple enough…. what voltage is V+ and what voltages are TX / RX?
Any ideas on which would be the better adapter?
