BLK-MD-BC04-B is the most powerful Bluetooth module currently on the market, the module uses Blue2.0, support the master-slave mode, support software / hardware setting master-slave mode, supports up to 29 AT commands and 9 automatic feedback instruction, support baud rate 1200 to 1382400. 29 AT control command +9 uplink downlink command to create the most powerful Bluetooth serial solution for you
Description
1, CSR mainstream Bluetooth chip, Bluetooth V2.0 protocol standard
2, the serial port module working voltage 3.3V, distance is 15 meters
3 baud rate default factory 9600, user can set.
4, support the software / hardware setting master-slave mode
5, working state indicator, connection status signal output and non connection, easy MCU to the module state tracking
6, the core module size: 26.7mm * 13mm * 2 mm
7, working current: pairing: 2 ~ 10mA pairing is not communication: 5 ~ 6Ma communication: 20mA
8, sleep current: don’t sleep, but support the low power mode
9, used for GPS navigation system, electricity and gas meter reading system, control system in industry field.
10, it can be seamlessly connected with the Bluetooth notebook computer, computer and Bluetooth adapter, PDA and other equipment
Application
This module is mainly used in the field of wireless data transmission in short distance. It is convenient to connect PC Bluetooth devices, data communication between two modules. Avoid complicated cable connection, can directly replace the serial line.

8 POS system, wireless keyboard, mouse
9 automation data acquisition system
10 wireless data transmission; the banking system
11 government street lamp energy-saving equipment
12 television interactive program voting equipment
13 wireless LED display system lever,
14 Bluetooth game Bluetooth controller
15 intelligent Home Furnishing, industrial control, building automation, security, computer room equipment wireless monitoring, entrance guard system
Characteristic
1, the power supply voltage 3.3V, the unpaired current about 2-10mA, pairing after about 20mA, the absolute prohibition of reverse power!
2, LED pin indicates Bluetooth connection state, the output pulse said no Bluetooth connectivity, high output that Bluetooth is connected and open port
3, the interface level 3.3V, can be directly connected to a variety of microcontroller (51, AVR, PIC, ARM, MSP430), 5V microcontroller is also can be connected directly, without MAX232 also cannot pass MAX232
4, module and computer access, MAX3232 chip is connected to the computer serial port
5, open to the effective distance of 15 meters, but not this distance connection do quality assurance
6, after the pair when full duplex serial use, without any knowledge of the Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity communication format, which is the most commonly used communication format, other format is not supported.
7, before the establishment of Bluetooth connection through the support of the AT instruction set baud rate, name, pairing password, save the power out parameter setting. Bluetooth connection will automatically switch to the transmission mode
8, small volume (2.7cm*1.3cm), factory production to ensure the quality of the patch, patch.
9, the link from the machine, computer, Bluetooth host, most with the Bluetooth mobile phone, PDA, PSP intelligent terminal pairing with Bluetooth function from the function and various, from the machine can not match
