This BlueBee wireless module is new product from Cytron Technologies, utilizing the XBee form factor, BlueBee is compatible with XBee adapter such as SKXBee (without module), XBee breakout board and Arduino-XBee shield. Though the form factor (pin out) is compatible with XBee module, BlueBee uses Bluetooth Technology. It is compact in size, the pinout is compatible with XBee which is suitable for all kinds of microcontroller systems that have 3.3V power out, the module utilize AT commands to set baud rate and other parameters.
The BlueBee module 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. However, it only provides SPP (Serial Port Profile) where it becomes serial COM port once it establish connection with master Blueooth.
BlueBee module's baudrate can modified using XBEE adapter. You can use SKXBEE-BOARD or XBEE Arduino controller receives the base plug, enabling Bluetooth wireless control.
Please note that the current version BlueBee Bluetooth module is only a slave module master and slave module. Communication among two BlueBees is not possible. Normally connection is initiated from Bluetooth Dongle (Laptop or computer), or Handphone that have Bluetooth. To enable BlueBee in master mode, please refer to this tutorial.
