BLUETOOTH BEE

This DFRobot Bluetooth Bee Bluetooth wireless module adapts XBEE design. It has compact size, the pinout is compatible with XBEE which is suitable for all kinds of microcontroller systems who have 3.3V power out, the module can use the AT commands to set baud rate. The Bluetooth Bee modules comes with an on-board antenna, the antenna provides better signal quality. It acts like a transparent serial port, which works with a variety of Bluetooth adapter and Bluetooth phone. The module has been tested with all the Bluetooth adapter on the market matching to use (with the Bluetooth, including laptops and mobile phones). Bluetooth Bee Bluetooth wireless module can modify the baud rate to use XBEE adapter. You can use XBEE Arduino controller receives the base plug, enabling Bluetooth wireless control.

AT Commands

The current version of the module only supports AT commands used to set the baud rate. The default baud rate for this module's AT mode is 38400bps. For regular use, the default baud rate is 9600.

Test Command

• Transmit:AT
• Return:OK

(No Carriage Return is Required)

Change Baud Rate

Entering AT Mode

Using Arduino Serial Terminal and USB Xbee converter
Place the module into AT Mode while powered off. Apply power to it and open the corresponding com port in Arduino IDE's serial terminal. Set the Baud rate to 38400 and the setting next to that to "both NL & CR". You should now be able to send AT commands to the Bluetooth bee.

NOTE: The bluetooth bee might come up as bluetooth bee or as bluetooth_V3
