Serial Port Bluetooth With ExpansionBoard Kits
Product list:
1. Master Bluetooth Module
2. Slave Bluetooth Module
3. USB to TTL conversion module
Bluetooth master/slave module has 4 pins:
Pin 1: *5 V power supply
Pin 2: Data sending Pin (which can be connected with the RXD serial
terminal of other other chips)
Pin 3: Data receiving Pin (which can be connected with the TXD
serial terminal of other other chips)
Pin 4: GND Ground
Here are some usage examples:
Example 1: PC serial port + RS***-TTL conversion circuit +
Bluetooth master module + Bluetooth slave module
Note: In the example above, master and slave bluetooths can
exchange their places, which will not affect data communications.
However, on occasions that confidential communications is required,
slave bluetooth is connected with PC and master bluetooth is
connected equipment terminal, because mobile phones and computers
with bluetooth or other Bluetooth devices can not search the master
module, but the slave module)
Example 2: USB-TTL conversion module + master Bluetooth module +
slave Bluetooth module
Note: In the example above, master and slave bluetooths can
exchange their places.
Example 3: PC Bluetooth adapter + master Bluetooth module + slave
Bluetooth module
Note: In example 3 PC Bluetooth adapter has to work with slave
Bluetooth module because it can not pair with master Bluetooth
module. Please install IVT Corporation BlueSoleil before using PC
Bluetooth adapter. Bluetooth mobile phones and Bluetooth devices
can also pair with slave Bluetooth module. Data communication can
happen between each other. But Bluetooth management software is
needed on Bluetooth mobile phone.
Example 4: Equipments with serial port + master Bluetooth module+
slave Bluetooth module
Note: In example 4, the two equipments can send or receive data
wirelessly. They were connected with master Bluetooth module and
slave Bluetooth module. When Bluetooth modules are powered on, they
will pair with each other automatically, without manually entering
the password.
Baud rate: ***0, ***0, ***0, ***0, ****0, ****0, ****0, *****0,
*****0, *****0, *****0, ******0. Users are free to change or set
it. The default baud rate is ***0.
Frequency: 2.4GHz*2.*8GHz. ISM Band
Bluetooth protocol: BlueTooth V2.0 standard
Receiving sensitivity: **5dBm
Operating Voltage: 5V
Operating temperature: **0 centigrade to ***5 centigrade
Power rating: Class2 (*6 dBm)
Reference Power consumption: *5mA(searching), 8mA(paired)
How to change the setting? (we do not recommend to modify the
default settings which can satisfy most needs)
Step 1: Modify the COM settings:
COM: (according to the PC)
Baud rate: ***0
Test bits: N
Data bits: 8
Stop bit: 1
Baud rate above *****0 is not recommend, because the signal
interference will make the system unstable. While baud rate is
above *****0, the baud rate can not be changed by PC. You have to
use MCU to send commands to modify it.
