    HC-02 serial to Bluetooth module, the slave module for wireless data transmission

    Naming Products description:
    HC-05, is a master-slave integrated Bluetooth serial module, the main switch from a directive, rich and complete instructions. (Supply voltage 3.3V ~ 3.6V)
    HC-06, is a master-slave integrated Bluetooth serial module, the main switch from a directive, instruction than HC-05, easy to use. (Supply voltage 3.3V ~ 3.6V)
    HC-02, can only be used for the machine to use, (supports AT commands modify the MAC address, support AT command to restore the default parameters).
    Host: to search from the device, other devices can not be search. (With white spots on the module)
    Slave: Used to be searched device and can not take the initiative to search for other devices.
    After connecting the master and slave is equivalent to using a serial line, this time, regardless of master and slave, which is transparent mode.
    HC-02 Product Description
    HC-02 Bluetooth serial communication module is based on digital transmission module Bluetooth V2.0 Bluetooth protocol. Wireless operating band for the 2.4GHz ISM, modulation is GFSK. Module maximum transmit power 4dBm, receiver sensitivity -86dBm.
    Stamp hole modules package, can patch welding, module size 26.9mm × 13mm × 2.2mm, easily embedded within the client application systems. (HC-02 can only be done from the machine)
    AT instruction set
    AT command to set the parameter module, the module in the unconnected state can be AT command operation, after entering the serial connection passthrough mode. Command with a carriage return line feed (/ r / n) end.
    Module startup takes about 150ms, so it is best on the module power 200ms before commencing AT instructions. Unless otherwise stated, after the restart parameter module AT command set to take effect. At the same time, modify the parameters and functions, power-down is not lost.
    1, test instructions
    Instruction: AT (/ r / n)
    Returns: OK.
    2, modify the Bluetooth name of the instruction
    Set command: AT + NAME = xxxxxxxxxxxxx (/ r / n)
    Query command: AT + NAME = (/ r / n)?
    The default name is Bluetooth module HC-02, can be set to a different name (limit within 20 characters).
    Example:
    Send: AT + NAME = HCKJ (/ r / n)
    Returns: OKsetNAME
    Send:? AT + NAME = (/ r / n)
    Returns: HCKJ
    3, modify instruction pairing password
    Set command: AT + PIN = xxxx (/ r / n)
    Query command:? AT + PIN = (/ r / n)
    Module default passcode is 1234, you can set other password (limit four digits).
    Example:
    Send: AT + PIN = 0000 (/ r / n)
    Returns: OKsetPIN
    Send:? AT + PIN = (/ r / n)
    Returns: 0000
    4, modify the Bluetooth address of the instruction
    Set command: AT + ADDR = xxxxxxxxxxxx (/ r / n)
    Query command:? AT + ADDR = (/ r / n)
    The address is 12 characters 0-F, or 16 hexadecimal characters.
    Example:
    Send: AT + ADDR = 1234567890AB (/ r / n)
    Returns: OK
    Setup is complete, you need to restart after the entry into force of the module!
    Send:? AT + ADDR = (/ r / n)
    Returns: 12,34,56,78,90, AB
    5, modify the baud rate command
    Set command: AT + BAUD = x (/ r / n) (modifying only the baud rate)
    AT + BAUD = x, y (/ r / n) (modify the baud rate and parity bit)
    Query command: AT + BAUD = (/ r / n)?
    Example:
    Send: AT + BAUD = 19200
    Returns: OK19200
    Module serial port baud rate was revised to 19200bps, parity and same as the original
    Send: AT + BAUD = 4800, E
    Returns: OK4800, EVEN
    Module serial port baud rate is revised to 4800bps, parity
    Send: AT + BAUD = 4800, O
    Returns: OK4800, ODD
    Module serial port baud rate is revised to 4800bps, Odd parity
    Send: AT + BAUD = 4800, N
    Returns: OK4800, NONE
    Module serial port baud rate is revised to 4800bps, no parity
    Send: AT + BAUD =?
    Returns: 4800, NONE
    The display module current baud rate and parity bits.
    6, restore factory settings command
    Command: AT + DEFAULT (/ r / n)
    Returns: OKsetDEFAULT
    The factory default parameters: NAME: HC-02
    BAUD: 9600, N0NE
    PIN: 1234
    7, to see all the parameters instructions
    Command: AT + RX (/ r / n)
    Returns: NAME = HC-02 (Bluetooth name)
    ADDR = xx, xx, xx, xx, xx, xx (12-bit address)
    PIN = 1234 (PIN code)
    BAUD = 9600, NONE (baud rate, parity)
    8, see the software version command
    Command: AT + VERSION (/ r / n)
    Returns: HC-02V1.0,2014-08-22
