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). It also expand five analog IOs that you can use it to connect other devices. The Bluetooth Shield could be setting to Master or Slave by user.

Serial port Bluetooth module is fully qualified Bluetooth V2.0+EDR(Enhanced Data Rate) 3Mbps Modulation with complete 2.4GHz radio transceiver and baseband. It uses CSR Bluecore 04-External single chip Bluetooth system with CMOS technology and with AFH(Adaptive Frequency Hopping Feature).

Features

• Crowduino/Arduino/seeeduino compatible.
• Standard Shield designed that you can use it easily.
• Up to10m communication distance in house without obstacle
• UART interface (TTL) with programmable baud rate (SPP firmware installed).
• Default baud rate: 38400, data bits: 8, stop bit: 1, Parity: No parity.
• Default PINCODE:0000
• A full set of configuration commands.
• On board PCB antenna.

Note

Only between master device and slave device can be paired with each other. Between Master and Master devices or Slave and Slave devices can't be paired each other. The Slave mode could be paired with PDA, PC etc.
