AT Command Set:
 HC-05 embedded Bluetooth serial communication module (hereinafter referred to as modules) has two operating modes: command-response mode and automatically connect mode, can be divided into the mainmodule automatically connect mode (Master) (Slave) three job roles and loopback (Loopback). When the moduleis automatically connected mode of operation, automatically according to pre-set data transmission connection;when the module is in order to respond to the operating mode can perform all of the following AT command,users can a variety of AT commands sent to the module for the module control parameters or release control commands. Can be achieved through the control module the external pin (PIO11,) input level, the dynamictransformation of the module status.

Pin definitions used by the serial module:
1, PIO8 connection LED, to indicate the module state, module power on after flashing a different state flashinginterval.
2.PIO9 connection LED, indicates that the module connection is successful, match the Bluetooth serial portconnection is successful, the LED long bright.
3. PIO11 module state switching feet high -> AT command response to working condition, low or floating ->Bluetooth regular work status.
4, the module has been with the reset circuit, re-power on to complete the reset.
 
To set the main modules:
1.PIO11 set high.
2.power-on module to enter the AT command response status.
3.HyperTerminal or other serial tools, set the baud rate 38400, 8 data bits, 1 stop bit, no parity, no flow control.
4.the serial port to send character "AT + ROLE \ r \ n" successful return "OK \ r \ n", where \ r \ n carriage return line feed.
5.PIO is low on power, the module re module, automatically search from the module, to establish a connection.
