This document discusses the history and architecture of Bluetooth technology. It describes Bluetooth piconets and scatternets, and how devices connect in these networks. It also covers Bluetooth profiles that define how devices interact, such as access, discovery, serial port, and object exchange profiles. Benefits of Bluetooth like synchronized information, printing, and using headsets are highlighted. Security aspects involving modes, passkeys, and threats like bluejacking and bluesnarfing are addressed. Current and potential future uses of Bluetooth at home, for home automation, with cell phones and clocks are presented before concluding.
