Abstract
Decided as a short-range wireless networking protocol, the distance that the Bluetooth technology can transmit is as far as dozens of meters. Bluetooth technology can normally provide cable-replacement technology to connect devices at home or in work place. Unlike IrDA interface, Bluetooth can overcome the obstacle without devices straight. To this extend, it has dominant superiority.
My project is on the basis of the technology of Bluetooth that supplied a connection between PPC and PC. Iinstant data and files can be transferred by building a transfer frame. Then, simulate simple system comprised of home electrical appliance. Firstly, this paper introduce Bluetooth technology and Bluetooth core protocol ,then emphasize RFCOMM protocol .Secondly, it introduce the way of carrying out the communication between PPC and PC. At last, the way is testified to succeed.
Key words:Bluetooth ，wireless , Serial Communication
