Bluetooth shield V1.1 by Seed Studio
The Bluetooth Shield integrates a Serial Bluetooth module. It can be easily used with Arduino/Seeedstudio for transparent wireless serial communication. You can choose two pins from Arduino D0 to D7 as Software Serial Ports to communicate with Bluetooth Shield (D0 and D1 is Hardware Serial Port). The shield also has two Grove connectors (one is Digital, the other is Analog) for you to install Grove modules.

Demonstration 1：Two Bluetooth Shield Connect
This demo will show you how to connect two Bluetooth shield.
You need two piece of Seeeduino V3.0, a Grove - Button, and a Grove - LED.
One Bluetooth Shield as Master while the other as Slave, and there's a Botton connect to the Master, a Led connect to Slave.
When the button press up, the led in Slave will change.
Hardware Installation
Firstly, we choose a Bluetooth Shield as Master, and plug Grove - Button to D8,D9 of this Bluetooth Shield.
For the Slave, we connetc Grove - Led to it's D8,D9 Grove. And D7 as TX, D6 as RX, as folowing:
