BLE Mate 2 bluetooth module to Arduino Uno without FTDI SmartBasic So I'm trying to hook up this BLE breakout board to an Arduino Uno. SparkFun has a hookup guide which seems to be great for someone who has an FTDI SmartBasic that is mentioned in the article. I don't have the SmartBasic board, and would like to see if this is possible without it.

I have hooked up the board to my Uno with the following pinouts:

GRN -&gt; Reset 
RXI -&gt; RX (tried with TX as well) 
TXI -&gt; TX (tried with RX as well) 
VIN -&gt; Tried 5V and 3.3V 
CTS -&gt; GND 
BLK -&gt; (No Connection)


I use their example code they have provided, uploaded without the RX and TX pins hooked up because, from what I notice, you cannot upload a program through the USB serial when these ports are in use. So after I upload the program through USB, I power the board with a battery and connect the RX and TX pins to the BLE board.

Has anyone either successfully hooked these up without the use of a SmartBasic? I'm a programmer by trade so I do my best to understand this side of the spectrum.
So I found out what I was doing wrong, and want to smack myself for it -.-

The answer was to simply hook up the BLK connection (which I guess is also ground) to a GND pin on the Arduino Uno.

Hope this ends up helping someone out.
