Hey Mon Ami !

Example:

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

using TechTweaking.Bluetooth;

public class BasicDemo : MonoBehaviour {

	private  BluetoothDevice device;
	public Text statusText;
	// Use this for initialization
	void Awake () {
		BluetoothAdapter.enableBluetooth();//Force Enabling Bluetooth
		device = new BluetoothDevice();
		device.Name = "HC-06";
		//device.MacAddress = "XX:XX:XX:XX:XX:XX";
		}
	public void Connect() {
		statusText.text = "Status : ...";
		device.connect();

	}
	public void Disconnect() {
		device.close();
	}

    public void SendOn()
    {
        if (device != null)
        {
            device.send(System.Text.Encoding.ASCII.GetBytes("1\n"));
        }
    }
    public void SendOff()
    {
        if (device != null)
        {
            device.send(System.Text.Encoding.ASCII.GetBytes("0\n"));
        }
    }
    /* Please note that this way of reading is only used in this demo. All other demos use Coroutines(Unity offers many tutorials on Coroutines).
	 * Just to make things simple
	 */
    void Update() {
		if (device.IsReading) {

			byte [] msg = device.read ();


			if (msg != null ) {
				string content = System.Text.ASCIIEncoding.ASCII.GetString (msg);

				statusText.text = "MSG : " + content;

			} 
		}
	}

(Reminder: Don't use versioning control, Git or alternative, is a professional fault.
And you need to be crazy or stupid to not use it... With all my respect ;) )
