Products naming Introduction
HC-05 is a master from the integration of Bluetooth serial module, the main switch from a directive, instruction rich range (supply voltage of 3.3V ~ 3.6V)
HC-06 is a master from the integration of Bluetooth serial module, the main switch from a directive, instruction than HC-05, easy to use. (Supply voltage 3.3V ~ 3.6V)
Host: to search from the device, other devices can not be search. (With white spots Bluetooth module)
Slave: Used to be searched device and can not take the initiative to search for other devices.
After connecting the master and slave is equivalent to using a serial line, this time, regardless of master and slave, which is transparent mode.
Note: HC-06 and HC-05 can be paired with each other communications
Product Description
1, using mainstream CSR Bluetooth chip, Bluetooth V2.0 protocol standards.
2, the module supply voltage: 3.3V ~ 3.6V.
3, the default parameters: 9600 baud, pairing code 1234, the mode of the slave.
4, the core module size is: 27mm x 13 mm x 2mm.
5, the working current: less than 50MA (with actual date).
6. Communication distance: open conditions under 10M, normal use of the environment around 8M.
7, for the GPS navigation system, utility meter reading systems, industrial control systems mining site can be seamlessly with Bluetooth notebook computers, computer plus Bluetooth adapter, PDA and other devices.
8, you can upgrade STC microcontroller wireless and download the program.
1, led pin indicates the status of the Bluetooth connection, the output pulse indicates no Bluetooth connectivity, high output indicates that Bluetooth is connected and open ports
2, the power supply voltage 3.3V, when unpaired current of about 30mA, after the pair about 10mA, the absolute prohibition of reverse power! Power absolute prohibition exceeds 3.6V!
3, interface level 3.3V, can be connected to a variety of microcontrollers (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller best 1K resistor in series with a direct connection to the module and then, according to specifications published schematics floor conversion, can not pass without MAX232 MAX232!
4, open to the effective distance of 10 meters, over 10 meters are possible, but do not do this to ensure the quality of the connection distance
5, after the pair finished on the same line when the serial port to use, supports 8 digits, one stop bit, parity or no parity (with specification shall prevail)
6. Set up a Bluetooth connection when not support 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
7, small size (2.7cm * 1.3cm), factory chip production, quality assurance patch.
PC, Bluetooth host, most Bluetooth phones, PDA, PSP and other intelligent terminal 8, the link from the machine, from a function with a variety of Bluetooth-enabled pairing between slaves can not be paired
Workaround 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.
Please observe the following modules and SCM connection (Bluetooth module voltage is 3.3V):
AT command set
First, the factory default parameters:
Slave baud rate: 9600, N, 8,1. Passcode: 1234; To require host mode, a single time, please indicate below.
Two, AT command set as follows:
1, the test newsletter
Send: AT (return OK, one second about hair once)
Returns: OK
2, change the Bluetooth serial port baud rate
Send: AT + BAUD1
Returns: OK1200
Send: AT + BAUD2
Returns: OK2400
1 --------- 1200
2 --------- 2400
3 --------- 4800
4 --------- 9600
5 --------- 19200
6 --------- 38400
7 --------- 57600
8 --------- 115200
9 --------- 230400
A --------- 460800
B --------- 921600
C --------- 1382400
Not recommended for use in more than 115,200 baud rate, signal interference make the system unstable.
After setting more than 115,200 computer unusable, use microcontroller programming in order to use this higher than 115200 baud rate and re-issue the AT command set low baud rate
After using the AT command set the baud rate, the next power-use without re-established, can be powered down to save the baud rate.
3, change the Bluetooth name
Send: AT + NAMEname
Returns: OKname
The current name to be set, that Bluetooth is searched name: parameter name. 20 characters or less.
Example: Send AT + NAMEbill_gates
Returns OKname
Then the Bluetooth name changed bill_gates
Parameters can be powered down to save, simply modify the time. PDA-side refresh service can see the Bluetooth name changed.
4, change the Bluetooth passkey
Send: AT + PINxxxx
Returns: OKsetpin
Parameter xxxx: you want to set a passcode, 4 bytes, this command can be used slave or master. Slave is the adapter or cell phone when asked to enter a passcode pop up window, then manually enter this parameter can be connected to the slave. Host is in the main Bluetooth module connected with a digital camera, a digital camera from a machine, find the camera pairing password, and then set up the White Bluetooth module, the master Bluetooth module can automatically connect the camera.
Example: Send AT + PIN8888
Returns OKsetpin
Then Bluetooth pairing password to 8888, the module at the factory default passcode is 1234.
Parameters can be powered down to save, simply modify the time.
