Introduction
The Bluetooth Shield integrates a Serial Bluetooth module. It can be easily used with Arduino 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.
Note: The Shield may not be compatible with some Bluetooth capable devices, like some HTC mobile phone (G7 with Android 2.33) and Apple devices with special profile on Bluetooth function.

Quick Test
Host-Slave mode: Communication between two different Bluetooth shields
- Select the Bluetooth shield communication port: BT_RX is connected to D6 of Digital-6, BT_TX is connected to Digital-7. Move the mode skeleton switch to lower position so that Bluetooth module will enter into AT command mode.
