Definitions
- the inquiring device will become the master and the responding device will become the slave in the eventual piconet, if a connection is established.
- the inquiring device To establish a connection, the inquiring device must enter the page state.
- the inquiring/paging device uses the information provided in the inquiry response packet, to prepare and send a paging message to the responding device.
- the inquiring/paging device uses the estimated clock CLKE and access code of the responding device (i.e., the eventual slave device) to temporarily synchronize with it. Since the inquiring/paging device intends to be the master, it includes an assignment of an active member address (AM_ADDR) in the paging message.
- AM_ADDR active member address
- Figure 3C illustrates the alternate embodiment wherein the access point 140 includes three devices, the piconet managing master device 140A, the scanning slave device 140B, and the inquiring/paging master device 140C.
- This figure shows the inquiring/paging master device 140C transmitting inquiry and paging packets in step 321 and establishing a connection with the mobile slave device in step 322.
- the inquiring/paging master device 140C then passes the mobile's connection to the piconet managing master device 140A in step 323.
- the access point master device is programmed to transmit inquiry and paging packets and to establish connections with mobile slave devices that respond to its inquiries.
- the access point slave device in programmed to primarily remain in an inquiry scanning mode to search for inquiry packets from mobile devices that are potential master devices and to pass control to the access point master device upon receiving a paging packet from a mobile device.
- mobile devices that are potential master devices and to pass control to the access point master device upon receiving a paging packet from a mobile device.
- the device 140B queries an available AM_Address from piconet managing master device 140A.
