This module is designed as a Slave and master two in one module+ Bluetooth XBee For Arduino. This module is used easily with other controllers and provides a Default baud rate of 38400. It is simply a Bluetooth Bee wireless module using an XBEE design. It comes in a compact size, compatible with the XBEE expansion base for a variety of 3.3V microcontroller systems. Using the AT command, the module sets to master-slave mode, baud rate, pairing password, the user information, default Baud rate: 38400, default slave mode, the pairing 1234.
The Bee Adapter in the module conveniently linked Bluetooth Bee and PC data exchange. Moreover, a sensor shield designed for the insertion of Bluetooth Bee to the Arduino, the convenience of Bluetooth data Arduino control. The highly efficient onboard antenna in the module transmits better signal quality over long distances. Thus transparent serial port used with a variety of Bluetooth adapters, Bluetooth phone paired. The module is designed  to work with all paired Bluetooth adapters (included with Bluetooth laptops and mobile phones)
Bluetooth Bee is defined as a simple breakout board for the Bluetooth Module, with a pin distance of 2.0mm, compatible with all XBee interface and XBee module, specifically for transparent wireless serial connection setup. This Bluetooth Bee module is configured to Master, Slave, or Loopback three different modes (HC-06 not for Master Mode). Thus it connects to or gets connected by other devices that support SPP protocol per configuration. This serial port Bluetooth module features fully qualified Bluetooth V2.0+EDR (Enhanced Data Rate) 3Mbps with a complete frequency range from 2.402 GHz to 2.480GHz. And also it uses a CSR Bluecore4-external single-chip Bluetooth system with CMOS technology and with AFH (Adaptive Frequency Hopping).
