HC-04/06 master device has a function of remembering the last paired slave device. As a master

device, it will search the last paired salve device until the connection is built. But if the WAKEUP

bottom is pressed, HC-04/06 will lose the memory and research the new slave device.

Fig 2 RF parameter Test Procedure

Guangzhou HC Information Technology Co., Ltd.

The way to the AT command mode: supply power to the module, it will enter to the AT mode if it

needn’t pair. The interval of command is about 1 second.

Default parameter: Baud rate:9600N81, ID: linvor, Password:1234

Send: AT (please send it every second)

2. Reset the Bluetooth serial baud rate

PC can’t support the baud rate lager than 115200. The solution is: make the MCU have higher baud

rate (lager than 115200) through programming, and reset the baud rate to low level through the AT

The baud rate reset by the AT command can be kept for the next time even though the power is cut

3. Reset the Bluetooth name

Guangzhou HC Information Technology Co., Ltd.

Parameter name: Name needed to be set (20 characters limited)

Now, the Bluetooth name is reset to be “bill_gates”

The parameter can be kept even though the power is cut off. User can see the new Bluetooth name

in PDA refresh service. (Note: The name is limited in 20 characters.)

4. change the Bluetooth pair password

Parameter xxxx: The pair password needed to be set, is a 4-bits number. This command can be used

in the master and slave module. At some occasions, the master module may be asked to enter the

password when the master module tries to connect the slave module (adapter or cell-phone). Only if the

password is entered, the successful connection can be built. At the other occasions, the pair can be finish

automatically if the master module can search the proper slave module and the password is correct.

Besides the paired slave module, the master can connect the other devices who have slave module, such

as Bluetooth digital camera, Bluetooth GPS, Bluetooth serial printer etc.

Then the password is changed to be 8888, while the default is 1234.

This parameter can be kept even though the power is cut off.

5. No parity check ( The version, higher than V1.5, can use this command )

Send: AT+PN (This is the default value)

6. Set odd parity check ( The version, higher than V1.5, can use this command )

7. Set even parity check( The version, higher than V1.5, can use this command )
