SHORT-RANGE RF ACCESS POINT DESIGN ENABLING SERVICES TO MASTER AND SLAVE MOBILE DEVICES

摘要

A short-range RF access point 140 contains two Bluetooth devices 140A and 140B. The first device 140A is programmed to remain a master device. The second device 140B is programmed to remain a scanning slave device. The two devices are connected to exchange clock, address, and synchronization information. The access point master device transmits inquiry and paging packets and establishes connections with potential slave devices 100C that respond to inquiries from the master device. The master device's clock is the piconet clock for the resulting connections. The access point slave device primarily remains in an inquiry scanning mode, searching for inquiry packets from mobile devices that are potential master devices. When the access point slave device receives the inquiry packets and paging packets from a mobile device, it then passes control to the access point master device.
