We choose Arduino Bluetooth Module Slave Wireless Serial Port 4P for our wireless communication purposes (http://www.ebay.com/itm/Arduino-Bluetooth-Module-Slave-Wireless-Serial-Port-4P-/150653185968?pt=LH_DefaultDomain_0&hash=item2313a12fb0).
To use this device in the mood working 100% correct, we have to use a resistor divider to reduce the operating Because PIC18f452's RX,TX operating in 5V-0V range but in this Bluetooth reviver it operates in 3.3V to 0V range. So we put up a voltage divider between the Arduino Bluetooth Module Slave Wireless Serial Port and the PIC's RX, TX pins. After setup according to the below diagram Bluetooth Module will start working. When you search for new Bluetooth it will appear as a other type of device.You can couple the device with your laptop using its embedded pin code. After that your PC will have a serial port open via Bluetooth. you can easily communicate with that.
