 Boshi BLU232 Bluetooth / serial converter to the computer or smart phone's Bluetooth signal converter RS-232 or RS-485 serial port. BLU232 high-performance, low-power Bluetooth wireless communications chips, built-in high-performance microprocessor for serial data transmission, can be widely used in various occasions short-range wireless communications, industrial control field. The product itself can be its own serial port to a computer with a serial debugging assistant program communication rate, and format settings. BLU232 can be used as a virtual serial port for Bluetooth signals expansion, without modifying the existing serial port software. 



 Hardware installation BLU232 the hardware installation is very simple: Plug the 5V power supply can be. Next to the power supply terminal, a small LED (light emitting diode) when the product is powered, the LED blinking when connected Bluetooth, if the connection is successful the LED will be lit. 

 BLU232 can connect to a computer or smart phone's Bluetooth signal, BLU232 on the equivalent of a wireless computer expansion RS-232/485 port. The serial port is the default baud rate is 9600, the passkey: 1234, the default name: BOLUTEK. 

 BLU232 RS-232/485 port 2 usefulness: a conversion as a Bluetooth serial port in the transmission mode, setting mode used on BLU232 product set. Note BLU232 DB-9 female and DB-9 pin RS-232 port, they are essentially the same mouth, just for the convenience of the user's. BLU232 DB-9 hole the own extrapolation computer, RS-232 pin holder, BLU232 DB-9 pin holder and the computer's RS-232 pin seat pin assignments are exactly the same, so it can be plugged directly into the RS-232 devices. BLU232 the RS-232 port RXD, TXD, GND signal. Reference of the RS-485 signal ground with RS-232 GND is the same, the same with an external 5V power supply GND. RS-485 port with a 600W surge protection.

 3, software installation and use 

 3.1 To extend the wireless serial port of computer Bluetooth 

 BLU232 can be extended for a computer with Bluetooth a wireless serial port. 1 BLU232 connected to the power supply. 2, the computer Bluetooth - Add Bluetooth devices, wireless scanning to find the Bluetooth BOLUTEK, enter the passkey: 1234, lights flashing. BLU232 default baud rate and other formats (9600, n, 8,1), the expansion of the serial number in windows XP / 7 default for COM4. Users can view the "Control Panel" "System \ Device Manager \ port", you will find an increase of a new Bluetooth communication port (COM4) "This is a virtual serial port number. Under WINDOWS can use serial debugging aides "and other software to open COM4 to communicate at this time of continuous bright light. Note the baud rate of serial communication software BLU232 baud rate. 

 3.2 extension for smart phones Bluetooth wireless serial 

 BLU232 can be extended for smart phones with Bluetooth a wireless serial port. 1, will BLU232 plug in the power light flashes. 2, Bluetooth - Add Bluetooth devices, wireless scanning to find the Bluetooth BOLUTEK, enter the passkey: 1234, lights flashing. BLU232 default machine state, the baud rate and format (9600, n, 8,1). ANDROID under serial communication for smart phones using the Bluetooth serial port. Apk software at this time of continuous bright light. 







 4, BLU232 the set instruction 

 BLU232 can use serial debugging assistant "software to set the baud rate and other parameters. 1 BLU232 connected to the power supply. 2, the computer Bluetooth - Add Bluetooth devices, wireless scanning to find the Bluetooth BOLUTEK, enter the passkey: 1234, lights flashing. (If you have paired successfully, do not have matched the right), now, do not open the Bluetooth serial port COM4; the computer's serial port using the DB-9 hole side RS-232 port (such as COM1 port) to the set; 4, run Serial debugging assistant software, sending a column type instruction, each instruction must Enter the end, is to be more struck by a carriage return key at the end of the instruction. 5, the default baud rate is 9600, but if you change the baud rate, then later send commands to the baud rate must be the new baud rate, of course, can change it back. 6, the instruction does not distinguish between uppercase and lowercase, the effect. Set is finished you can open a Bluetooth serial port COM4 and communicate! 






 Fill in the serial debugging aides send bar AT + the HELP and then struck the carriage return line feed, then the cursor in the second line, press the "Manual Send, it will display a variety of AT commands in the receiving column. 

 The following is a common AT commands, pay attention to the last to add a carriage return line feed is not case sensitive. 

 AT + BAUD1 set the baud rate of 1200; the AT + BAUD2 set the baud rate is 2400; 

 AT + BAUD3 set the baud rate of 4800; the AT + BAUD4 set the baud rate to 9600 (default); 

 AT + BAUD5 set the baud rate of 19200; AT the + BAUD6 set the baud rate to 38400; 

 AT + BAUD7 set the baud rate to 57600; AT + BAUD8 set the baud rate for
