A02:HC-05 Bluetooth Wireless Serial Port Module

Tips:

TXD: the sending end , generally expressed as their transmitter, normal communication must be connected to RXD another device .
RXD: the receiving end, generally expressed as their receiving end, the normal communication TXD must be connected to another device.
Itself when normal communication TXD RXD devices connected forever !
Collected spontaneously : RXD when normal communication to other devices connected TXD, so if you want to receive data transmitted by its own name suggests , it is their own to receive data transmitted , which is directly connected to its own TXD RXD, used to send and receive test itself is normal, is the quickest and easiest test method, when a problem first do the test to determine whether a product failure. Also known as the loopback test .

Level logic:

TTL level: typically binary data representation , +5 V equivalent to the predetermined logical 1, 0V is equivalent to logic 0, the system is called a TTL signal is positive logic
RS232 level: -12V used to -3V, equivalent to a logic 0, +3 V to +12 V logic level is equivalent to logic 1 , negative logic

Features :

1, the core module from the module using the HC-05 , leads interface includes VCC, GND, TXD, RXD, KEY pin ,
pin-out Bluetooth connection status (STATE), not connected to the output low , after connecting the output high

2, led indicate Bluetooth connection status , Bluetooth connection means no flash , slow flash indicates enter AT mode ,
double flash indicates Bluetooth is connected and open ports

3, bottom set anti-reverse diode with 3.3V LDO, the input voltage is 3.6 ~ 6V, when unpaired current of
about 30mA, the pairing of about 10mA, the input voltage must not exceed 7V!

4, the interface level is 3.3V, you can directly connect a variety of SCM (51, AVR, PIC, ARM, MSP430 , etc. ),
5V microcontroller can also be connected directly , not through without MAX232 MAX232!

5, open to 10 meters effective distance ( power rating of CLASS 2), more than 10 meters are possible,
but do not make this connection to ensure the quality of distance

6, after the pair when using full-duplex serial port , without having to know any Bluetooth protocol support 8 data bits,
1 stop bit, parity can be set communication format , which is the most common communication format , not support other formats.

7, can be pulled 34 feet into the AT command mode to set parameters and query information

8, small size (3.57cm * 1.52cm), chip production plant to ensure the quality of the patch .
And set transparent shrink tube , dust and beautiful, and there is some anti-static capabilities.

9, can be switched via AT commands as master or slave mode ,
the device can be connected via AT commands specified

10, support from the Inter- standard baud rate 4800bps ~ 1382400bps

Usage:

After pairing just as the same as using the serial port baud rate can be fixed , so long as it is fixed baud ,
8 data bits, no parity , communication format of serial devices can be wired directly to the serial port
and replace the original do not need to modify the program .
Such as data acquisition , smart car , serial printers, dot matrix screen control , such as outdoors .

Paired with a computer : fit between computers via Bluetooth serial communication with the device , using the same method and serial
Paired with the phone : Good room phone via Bluetooth serial communication with devices using the same method and serial

Paired with a Bluetooth Host : For two devices directly via Bluetooth serial communication, such as between
the microcontroller and microcontroller serial cable with microchips , etc., using the same method and serial

Flexible use:

Baud rate conversion, because the receiver and the sender can choose their own baud rate,
in a small amount of data when you can use as a device baud rate conversion.
A master-slave module can pair with most computers, smartphones, PAD and PSP with bluetooth function.

Wiring instructions:
VCC: Connect to positive power source
GND: Connect to negative power source
RXD: Connect to receiving terminal
TXD: Connect to sending terminal

Note:
The working voltage is 3.6-6V, and 7V is forbidden.
Please make sure that you know how to use it before using.

Package List:

1 x HC-05 Wireless Serial Bluetooth Transceiver Host Slave / Master Module With 6 Pin Dupond

A03:Arduino Compatible Bluetooh Bee HC-05 Wireless Bluetooth Module

Specification:
Note:It's HC-05 Bluetooth module Slave and master two in one module
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.
