Note:It's HC-05 Bluetooth module Slave and master two in one module
Bluetooth Bee Bluetooth wireless module using XBEE design, compact size, compatible with XBEE expansion base for a variety of 3.3V microcontroller systems, modules can use the AT command set master-slave mode, baud rate, pairing password, the user information, default baud rate: 38400, default slave mode, the pairing 1234.
Module uses 3.3V power supply.
Never use more than 3.3V power supply, which may destroy the module
Modify the baud rate after a reboot of the module
Bluetooth pairing password is 1234
Default Baud Rate: 38400
With recommendations: Bee Adapter, conveniently linked Bluetooth Bee and PC data exchange Sensor Shield, for insertion Bluetooth Bee to the Arduino, the convenience of Bluetooth data arduino control Bluetooth adapter for Bluetooth and Bluetooth Bee, etc. from the device paired.
Comes with efficient on-board antenna, the antenna exposed transmit better signal quality over longer distances, transparent serial port can be used with a variety of Bluetooth adapter, Bluetooth phone paired. User-friendly design to facilitate the secondary development.
The module has been tested to work with the market all paired Bluetooth adapter (included with Bluetooth laptops and mobile phones)
This Bluetooth module supports master and slave mode, the user can set many detailed parameters AT commands. Way than using a separate slave mode is more freedom and flexibility, can be adapted to the special needs of more users. General and PC, PDA and other Bluetooth devices can be paired to slave mode.
