HC-06 Bluetooth module with 4pin RS232 TTL serial
HC-06 Bluetooth module with 4pin RS232 TTL serial
I. JY-MCU-06 HC-06 Bluetooth Transeiver RF Module Wireless Serial 4pin;
II. the core module from the module using the HC-06 , leads interface includes VCC, GND, TXD, RXD, aside LED status output pin , the microcontroller can be connected via Bluetooth to determine whether the pin state , KEY pin on the slave invalid
HC-06 with 4 pin bluetooth module
Product Features :
1, the core module from the module using the HC-06 , leads interface includes VCC, GND, TXD, RXD, aside LED status output pin , the microcontroller can be connected via Bluetooth to determine whether the pin state , KEY pin on the slave invalid
2, led indicate Bluetooth connection status , flashes to indicate there is no Bluetooth connection , Steady Bluetooth port is connected and turned on
3 , bottom 3.3V LDO, the input voltage 3.6 ~ 6V, when unpaired current of about 30mA, the pairing of about 10mA, the input voltage must not exceed 7V!
4 , the interface level is 3.3V, you can directly connect a variety of SCM (51, AVR, PIC, ARM, MSP430 , etc. ), 5V microcontroller can also be connected directly , not through without MAX232 MAX232!
5 , open to 10 meters effective distance of over 10 meters are possible, but do not make this connection to ensure the quality of distance
6 , after the pair when using full-duplex serial port , without having to know any Bluetooth protocol, but only supports 8 data bits, 1 stop bit , no parity communication format , which is the most common communication format , not support other formats .
7 , establish a Bluetooth connection when not support setting the baud rate , the name , the pairing password via AT commands , parameter set -down to save . After Bluetooth connection is automatically switched to transparent mode
8 , small size (3.57cm * 1.52cm), chip production plant to ensure the quality of the patch .
9 , the link from the machine, computer , Bluetooth with Bluetooth from a host with a variety of functions , most Bluetooth phones , PDA, PSP and other intelligent terminal pairing between slaves can not be paired .
Tips ( very important ) :
TXD: the sending end , generally expressed as their transmitter, normal communication must be connected to RXD another device .
RXD: the receiving end, generally expressed as their receiving end, the normal communication TXD must be connected to another device.
Itself when normal communication TXD RXD devices connected forever !
Collected spontaneously : RXD when normal communication to other devices connected TXD, so if you want to receive data transmitted by its own name suggests , it is their own to receive data transmitted , which is directly connected to its own TXD RXD, used to send and receive test itself is normal, is the quickest and easiest test method, when a problem first do the test to determine whether a product failure. Also known as the loopback test .
Note:
input power supply 3.3~6V, Prohibit more than 7V
No "Automatically prevent power supply peversing func", so please correctly connect power supply
We advise to install "Bluetooth master module"
The "State" is output foot for LED status, when bluetooth "Unconnected", output "Pulse" ; when bluetooth "connected", output "High level", we can determine the states from "MCU"
If only the board , No any "Bluetooth Function "
