| Summary: | The invention disclosed broadly relates to ubiquitous computing and more particularly relates to improvements in short range RF technology.
A short-range RF access point contains two Bluetooth devices. The first device is programmed to remain a master device. The second device 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 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. Several embodiments are disclosed for passing control from the access point slave to the access point master. |
