5 serial procedures of other intelligent devices (such as PDA, PSP, various brands of mobile phone, etc.) , in addition to the above description can provide information other information

The following is not a product quality issues are wiring error causes, not the warranty will not be returned:
a cause, since the spontaneous resumption of the test is successful, the use of the TXD or RXD with ground short circuit
, power anti-reverse module reversed power lead to damage

Tips (very important):
TXD: the sender, usually expressed as a sender, normal communication must be connected to another device RXD.
RXD: Receive-side, generally expressed as the receiving end, the normal communication must be connected to another device TXD.
Normal communication when the TXD is always connected to RXD of equipment!
Spontaneous resumption other equipment TXD RXD pick: when normal communication, so if you want to receive the data of their own to send the name suggests, is to receive their data sent, that is itself the TXD directly connected to the RXD to the test itself to send and receive is normal, is the quickest and easiest method of testing, when a problem occurs, do the first test to determine whether a product failure . Also known as the loopback test.

Logic level:
TTL level: usually data representation binary, the provisions of +5 V is equivalent to logic "1" and 0V is equivalent to logic "0", known as TTL signal system, the positive logic
RS232 level:-12V to -3V, equivalent to the logic "0", +3 V to +12 V logic level equivalent to logic "1", the negative logic

Features:
1, the core module using HC-07 from the module, leads to the interface consists of the VCC, GND, TXD, RXD, can be directly connected microcontroller serial
led indicates that Bluetooth connection status, blinking means no Bluetooth connectivity, Always said that Bluetooth is connected and open ports
, floor to set anti-reverse diode with 3.3V LDOs, input voltage of 3.6 ~ 6V, when the unpaired current is about 30mA, 10mA, paired input voltage to prohibit more than 7V!
4, the interface level is 3.3V, you can directly connect a variety of microcontroller (51 AVR, the PIC, ARM, the MSP430), 5V MCU can be connected directly, without the need MAX232 can not pass through the MAX232,! open to the effective distance of 10 meters. more than 10 meters is possible, but not this distance connection quality to do to ensure that six paired full-duplex serial port to use, without having to know any Bluetooth protocol, but supports only 8 data bits, 1 stop bit, no parity communication format, which is the most common communication format does not support other formats. Establish a Bluetooth connection supported by AT command set the baud rate, the name of the pair, set the parameters of power-down save . Bluetooth connection after automatically switch to the pass through mode , small size (3.57cm * 1.52), chip production factory to ensure that the patch quality. And sets of transparent heat-shrinkable tube, dust appearance, and there is some anti-static capability. 9, the link to the slavefunction with a variety of Bluetooth-enabled computer, Bluetooth host, the majority of Bluetooth-enabled mobile phone, PDAs, the PSP and other intelligent terminal pairing between the slave can not be paired.



Purposes:
matching need only as a fixed baud rate of serial port the same use can be, so long as it is "fixed baud rate, 8 data bits, no parity communication format serial device can directly replace the original wired serial port without the need to modify the program. Such as data acquisition, smart car, serial printer, outdoor lattice screen control and so on. Use:suitable for computer with devices via Bluetooth serial communication, paired with the same serial and cell phonepaired with your computer : suitable for mobile phone with the devices via Bluetooth serial communication, use the same serial port with the Bluetooth host pair: suitable for both devices directly through the Bluetooth serial communication, such as between the MCU and the MCU, wired serial port between with the microcontroller, using the methods and serial

Alternative use: the
baud rate of transformation, because the receiver and the sender can choose their own baud rate, when a small amount of data can be used as a baud rate of transformation equipment.

Module with a microcontroller, please follow the following link:

The following are the wrong connection method:

The following is really making a map to the slave module

The final product is put on heat shrink tube

if you need cp2102 pls tel me , the cp2102 add 3.5usd/pcs ,
