1. You can enter the EU and sell plant
2. Can the Bluetooth on the duct label,
 
and also Nothing than certified ducts more
 
Selling and convincing it !

duct description:

BLK-MD-BC04-B is the most powerful currently available serial port Bluetooth module module Blue2.0, master-slave mode support, support for hardware / software set master-slave mode, It supports up to 29 AT commands and nine automatic feedback instruction, supports baud 1200-1382400. 29 AT downlink control command +9 bar upward instruction for you to create the most powerful Bluetooth serial solutions!


Second, the duct series naming rules introduced
BC04-B And BC04-A The difference:

BC04-B Is the master, the master switch from the integration of Bluetooth serial module from a command, rich and complete instructions

BC04-A From module ducts, can only be done from the setting, the use of simple, inexpensive

BC04-B With distinction from other similar ducts:




Third, the duct description

 

1 , Adopt CSR Mainstream Bluetooth chip, Bluetooth V2.0 tocol Standards

2 , Serial module operating voltage 3.3V From generally 15 meters

3 , The default baud rate of 9600 The user can set.

4 , Support software / Hardware setup master and slave mode

5 , Working status indicator, connected to the non-connected state signal output, easy MCU The module status tracking

6 , Core Module Size is: 26.7mmx 13mm x 2.2 mm

7 , Working current: pairing: 2 ~ 10mA Pairing communication has not been completed: 5 ~ 6Ma Communication: 20mA

8 , Sleep current: less sleep, but supports low-power mode

9 , For GPS Navigation system, utility meter reading systems, industrial control systems mining site.

10 , You can add Bluetooth notebook computers, computer Bluetooth adapter, PDA And other equipment to seamlessly connect



Fourth, duct applications
This module is mainly used in the field of wireless transmission of data over short distances. Can be easily and PC Bluetooth device is connected, it can also exchange data between the two modules. Avoid cumbersome cable connections, direct serial cable replacement .

V. Features

 

1, the power supply voltage of 3.3V, when unpaired current is about 2-10mA, paired about 20mA, the absolute hibition of reverse power!

2, led pin indicates the Bluetooth connection status, pulse output means no Bluetooth connectivity, high output indicates that Bluetooth is connected and open ports

3, interface level 3.3V, can be directly connected to various microcontrollers?51, AVR, PIC, ARM, MSP430, etc.?, 5V MCU also can be connected directly, without MAX232 MAX232 can not go through!

4, the computer module and then followed MAX3232 chip connected to the computer's serial port

5, open to the effective distance of about 15 meters, but do not make this connection the of distance

6, after the pair when full-duplex serial interface, without having to know any Bluetooth tocol, but only supports 8 data bits, 1 stop bit, no parity communication format, which is the most common communication format does not support other formats .

7, when the Bluetooth connection is not established support setting the baud rate, name, passkey by AT commands, power-down save parameter settings. After the Bluetooth connection is automatically switched to transparent mode

8, compact?2.7cm * 1.3cm?Factory chip duction the of the patch.

9, the link from the machine, computer, Bluetooth with Bluetooth from the host with a variety of functions, most Bluetooth mobile phones, PDA, PSP and other intelligent terminal pairing from not pairing between the machine




Sixth, the setting module master-slave mode and method steps of:

Hardware settings:

Master mode: 1 The PI0 (4) soft/ From the main port hardware settings: low ( Or vacant) Setting the master-slave mode to hardware

2 ,will PIO (5) from the main hardware port settings: Set 3.3V high


Slave mode: 1 The PI0 (4) soft/ From the main port hardware settings: low ( Or vacant) Setting the master-slave mode to hardware

2 The PIO (5) From the main port hardware settings: Landmark ( Or vacant)

 

Software settings:

Master mode: 1 The PI0 (4) soft/ From the main port hardware settings: set to 3.3V High

2 Open HyperTerminal or other serial debugging tools to set the baud rate 9600 , 8 data bits Bits, 1 stop bit Bits, no parity, no flow control.

3 , Serial port character AT + ROLE1 \ r \ n, the successful return of + ROLE = 1 \ r \ n OK \ r \ n, where \ r \ n is a carriage return line feed

Slave mode: 1 The PI0 (4) soft/ From the main port hardware settings: set to 3.3V High

2 Open HyperTerminal or other serial debugging tools to set the baud rate 9600 , 8 data bits Bits, 1 stop bit Bits, no parity, no flow control.

3 , Serial port characters AT + ROLE0 \ r \ n , The successful return of + ROLE = 0 \ r \ n OK \ r \ n , Where \ r \ n A carriage return line feed
