E . Product Features
1, the power supply voltage of 3.3V, unpaired current approximately 2-30mA, paired approximately 10 mA absolute prohibition reversed power
2, led pin indicates connection status, the output pulse means no connectivity, high output indicates that is connected and turned on the port
3, the interface level 3.3V, can be connected directly to a variety of SCM (51, AVR, PIC, ,MSP430, etc.), the 5V microcontroller can be connected directly, without MAX232 can not go through the MAX232!
4, the module with the computer connected to the computer's serial port, then the MAX3232 chip
5, open to effective distance of 15 meters, but this distance to do to ensure the quality of the connection
6, when paired with full-duplex serial port to use, do not need to know any of protocol, but only supports 8 data bits, 1 stop bit, no parity communication format, which is the most commonly used communication format, not support other format .
7, establishing a connection support through the AT command set the baud rate, name, passkey, power-down save parameters set. connection automatically switch to transparent mode
8, small size (2.7cm * 1.3cm), the factory chip production to ensure the quality of the patch.
9, the link from the machine, from the function with a variety of -enabled computer, host, most with a -enabled cell phone, PDA, PSP, and other intelligent terminal pairing between the slave can not be paired
F . The module wiring methods and procedures:
Module connected with the computer: 1 TTL level converted into RS232
2, module power supply 3.3 V
TX and RX then RX to TX ground
Module with TTL level MCU connected: 1 RX connected to TX and RX to TX ground
2, the module power supply 3.3V
G , the module enters the AT test method:
1, the module power supply 3.3
2, open HyperTerminal or other serial debugging tools
3, open HyperTerminal or other serial debugging tools to set the baud rate (default 9600), 8 data bits, 1 stop bit, no parity, no flow control
TTL electric level turn into a the RS232 computer serial port connection
5, to send commands for the AT (no carriage return line feed) returns OK
H . AT command set
1, test communications
Send: AT (return OK, one second left and right)
Back: OK
2, change the serial communication baud rate
Send: AT + BAUD1
Back to: OK1200
Send: AT + BAUD2
Back to: 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
Recommended not to use more than 115200 baud rate, in order to avoid signal interference can cause system instability. The settings over 115,200 with a computer is not available, use microcontroller programming in higher than 115200 to use this baud rate and re-issue the AT command set low baud rate
AT command set baud rate, the next power do not need to set up and can be powered down to save the baud rate.
3, change the name
Send: AT + Namena
Back to: OKNA
Parameters NA: To set the current name, the name of the search. 20 characters or less.
The parameters can be powered down to save, simply modify the time. PDA the end refresh can see the name changed.
4, change the pairing password
Send: AT + PIN3456
Returns: OKsetpin
Parameter 3456: To set a passcode, 4 bytes, this command can be used from the machine or host. The slave adapter or mobile phone pops up to enter when pairing the password window, manually enter this parameter can be connected from the machine. Host is in the main module connected digital camera, digital camera from the machine, find the camera pairing password, and then set up the White module, the main module can automatically connect the camera.
