Description: HC05 Serial Port Bluetooth
you need to attach this to a computer. You can either solder a 6-pin header or individual wires.Unit comes without a connector. Please see related male and female pins below. And now, we provide HC-05/06, HC-05 could be setting to Master or Slave by user. HC-06 just be Master or Slave, that could be customized. This module default is HC-06 with Slave mode.

It has 6 pins,
1.Key/EN:It is used to bring Bluetooth module in AT commands mode. By default this pin operates in data mode. Key/EN pin should be high to operate Bluetooth in command mode. The default baud rate of HC-05 in command mode is 38400bps and 9600 in data mode.HC-05 module has two modes,
- Data mode: Exchange of data between devices. Baud rate is 9600bps in data mode.
- Command mode: It uses AT commands which are used to change setting of HC-05. Baud rate is 38400bps in command mode.
2. VCC: Connect 5 V or 3.3 V to this Pin.
3. GND: Ground Pin of module.
4. TXD: Connect with Microcontroller RXD pin of Microcontroller. Transmit Serial data (wirelessly received data by Bluetooth module transmitted out serially on TXD pin)
5. RXD: Connect with Microcontroller TXD pin of Microcontroller. Received data will be transmitted wirelessly by Bluetooth module.
6. State: It tells whether module is connected or not. It acts as a status indicator.
Be paired must Master devices and Slave devices each other.Master and Master devices, Slave and Slave devices can’t paired each other. The HC-06 (just suppy slave mode and more easy) Slave mode could paired with PDA, PC etc.
