Abstract
Abstract A system for operating a cellular phone using Bluetooth with a car kit is described. The Bluetooth protocol is used to communicate between the cellular phone and the car kit. A communication can be established between the cellular phone and the said car kit. In one mode, the car kit can be made to assume the identity of the cellular phone and transmit as if it were the cellular phone itself. In another mode, the car kit can become a hands-free set for the cellular phone which communicates with the cellular phone via Bluetooth.
