Bluetooth Shield is an easy to use module compatible with existing Arduino/Seeedstudio, based on Serial port Bluetooth module, designed for transparent wireless serial connection setup. You can choose XDUINO’s Digital PIN D0->D7 as Software UART to communicate with Bluetooth Shield(and D0,D1 also is Hardware UART). It has two Twig connectors(one is Digital,the other is IIC/Anolog) for you to install twigs.

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). Hope it will simplify your overall design/development cycle.

Hardware Features
– Seeedduino/Arduino compatible.
– Typical -80dBm sensitivity.
– Up to +4dBm RF transmit power.
– Fully Qualified Bluetooth V2.0+EDR 3Mbps Modulation.
– Low Power Operation.
– PIO control.
– UART interface with programmable baud rate.
– Integrated PCB antenna.

Software Features
– Default Baud rate: 38400, Data bits:8, Stop bit:1,Parity:No parity.
– Supported baud rate: 9600,19200,38400,57600,115200,230400,460800.
– Status instruction port PIO1: low-disconnected, high-connected(3V3); Can be read from ANALOG PIN 2 (A2).
– PIO10 is connected to red led, PIO11 is connected to green led. When master and slave are paired, red and green led blinks 1time / 2s in interval, while disconnected only green led blinks 2 times/ s.
– Auto-connect the last device on power as default.
– Permit matched device connect by default.
– Default PINCODE:”0000”.
– Auto-reconnect in 30 min when disconnected as a result of beyond the range of connection.

Application Ideas
– As a Wireless Serial Port for Arduino / Seeeduino and other MCUs
– As a Bluetooth Serial Port for PC when connected with UartSBee
