Product Description:
1, the core module from the module using HC-06, leads TTL level interface includes VCC, GND, TXD, RXD, and RS232 level of male female each one, TTL level RS232 interface higher priority than
2, led indicate Bluetooth connection status, flashes to indicate no Bluetooth connectivity, steady indicates that Bluetooth is connected and open ports
3, the module must be an external power supply to work, the power from the VCC and GND pin module inputs. Bottom set LDO, with anti-reverse polarity protection, input voltage 3.6 ~ 6V, when unpaired current of about 30mA, after the pair about 10mA, the input voltage must not exceed 7V!
4, TTL interface level 3.3V, can be directly connected to a variety of SCM (51, AVR, PIC, ARM, MSP430, etc.), DB9 RS232 interface is a standard level, only TXD, RXD, GND signal pin valid
5, open to the effective distance of 10 meters (power rating of CLASS 2), does not exceed the quality of the connection made to ensure that this distance
6, after the pair when using full-duplex serial, DB9 port supports 1200bps ~ 115200bps common baud, TTL interface supports baud rates used between 1200 ~ 1382400bps, without having to know any Bluetooth protocol supports only 8 data bits, 1 stop bit (parity can be set) communication format, which is the most commonly used communication format that does not support other formats.
7, when a Bluetooth connection is not established (ie LED flashes) supports setting the baud rate, the name by AT commands, pairing password, power-down save parameter settings. After the Bluetooth connection is automatically switched to transparent mode
8, small size, excluding DB9 connector size (3.98cm * 1.52cm), factory chip production, quality assurance patch. And sets of transparent heat shrink tubing, both dust and beautiful but also anti-static.
9, the link from the machine, computer, Bluetooth with Bluetooth function from the host with a variety of functions, most Bluetooth phones, PDA, PSP and other intelligent terminal pairing between slaves can not be paired.
Product Use:
After pairing just 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, intelligent vehicles, serial printers, dot matrix screen control, such as outdoors.
Paired with a computer: for between computers via Bluetooth serial communication with the device, using the same method and serial
Paired with your phone: for between the phone with a Bluetooth device via serial communication, 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 the microcontroller serial cable with microchips, etc., using the same method and serial
Note:AT commands can't be sent through bluetooth. Module can only be paired to one device at time. If other pairing is needed, reset button has to be pressed. AT commands are case sensitive. AT mode connecton specs are 9600 8 n 1. Baud speed AT command is AT+BAUD1 where the number digit correspond baud speed.
Workarount 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.
The following information is not available:
1, the paper manual and CD-ROM
2, the original design documents, including but not limited to SCH documents, PCB files
3, various microcontroller end testing procedures
4, other smart devices (such as PDA, PSP, mobile phones of various brands) serial procedures
Package :
1pc DB9 RS232 Wireless Bluetooth Serial Module Slave 4 Pin
8. Open HyperTerminal or other serial tool, set the baud rate 38400, 8 data bits, 1 stop bit, no parity bit, no Flow
