After above-mentioned at least one second point-to-point wireless communication apparatus receives sync signal, will be synchronous with the first point-to-point wireless communication apparatus.And each at least one second point-to-point wireless communication apparatus also can broadcast this sync signal further, to make other point-to-point wireless communication apparatus receive, and also wireless communication apparatus point-to-point with first is synchronous to make other point-to-point wireless communication apparatus.So, by making the point-to-point wireless communication apparatus receiving sync signal switch to main device, and broadcast synchronization signal, multiple point-to-point wireless communication apparatus can be made to realize synchronous.And the present embodiment only need transmit sync signal, do not need to transmit a large amount of data, the object making all-pair point wireless communication apparatus synchronous can be reached.Further, because do not need to use server, number of connection and the framework of multiple point-to-point wireless communication apparatus can optionally adjust, and make the present embodiment also have the large advantage of system architecture elasticity.
Now for point-to-point wireless communication apparatus for blue-tooth device illustrates, but the present embodiment is also applicable to the point-to-point wireless communication apparatus of other types.
The blue-tooth device of the present embodiment can be set to main device, also can be set to slave unit.Please refer to Fig. 2, it illustrates operational flowchart when blue-tooth device is main device.When blue-tooth device is main device, as shown in step 202, being opened by seek mode of blue-tooth device.In the effective range of blue-tooth device, blue-tooth device can carry out blue tooth wireless communication with other blue-tooth devices.Other blue-tooth devices in effective range can search this blue-tooth device, to carry out line.In current bluetooth compliant, a main device such as can be connected with the slave unit of the slave unit of 7 active (Active) states or 255 standby (Standby) states at most simultaneously.
Then, as indicated in step 204, judging whether that the quantity of the slave unit of the active state be connected with main device is greater than a predetermined quantity, such as, is the quantity of bluetooth compliant book defined.If so, then enter step 206, if not, then get back to step 202.And in step 206, then being closed by seek mode by blue-tooth device, and be no longer connected with other slave unit.
Please refer to Fig. 3, it illustrates operational flowchart when blue-tooth device is slave unit.When blue-tooth device is slave unit, as shown in step 302, the seek mode of blue-tooth device is opened.Then, enter step 304, near search, whether have the blue-tooth device can opened by seek mode.If not, then step 302 is got back to; If so, then enter step 306, blue-tooth device with can be matched by the blue-tooth device that seek mode is opened, to carry out line.Afterwards, then enter step 308, the seek mode of blue-tooth device is closed, and open can by seek mode, that is this will be originally for blue-tooth device of slave unit will switch to main device.
Now lift an example to be further described in detail as follows.Please refer to Fig. 4 A to Fig. 4 D, it is shown can perform the schematic diagram of example when the synchronous Bluetooth system of point-to-point signal carries out grouping.Node 1 to 8 represents 8 different blue-tooth devices, and node 1 can be considered the first above-mentioned point-to-point wireless communication apparatus, and node 2,3 and 4 can be considered three the second above-mentioned point-to-point wireless communication apparatus.
First, node 1 as main device, can being unlocked by seek mode of node 1, and there is an effective range 402, as shown in Figure 4 A.Because node 2,3 and 4 is positioned at this effective range 402, therefore node 2,3 and 4 will be first as slave unit (Slave device), and the seek mode of node 2,3 and 4 will be unlocked.
Afterwards, as shown in Figure 4 B, node 2,3 and 4 matches with node 1 respectively.Generally speaking, blue-tooth device must via after pairing, and two blue-tooth devices could lines and communicating with one another mutually.Bluetooth technology alliance (Bluetooth Special Interest Group, SIG) on July 26th, 2007, V2.1 new standard is proposed, new matching method-safe and simple pairing (Secure Simple Pairing, SSP) is proposed in fail safe.Safe and simple pairing has four kinds of operator schemes: (Passkey Entry) pattern keyed in by outer (the Out of band) pattern of pattern that numeral compares (Numeric comparison), on-line operation (Just Work) pattern, frequency band, golden key.Because on-line operation pattern only needs user to carry out confirming that (confirm) can complete pairing after operating, therefore be suitable for the environment not high to demand for security.In the pairing of the present embodiment, such as, can the on-line operation pattern of the simple matching technology of use safety realize, to reduce system complexity.
As shown in Figure 4 B, after node 2,3 and 4 and node 1 complete pairing, node 2,3 and 4 is connected to form a blue tooth radio network and communicates with one another with node 1.The network that this kind main device is connected with multiple slave unit is called microgrid (Piconet).
Afterwards, node 2,3 and 4 switches to main device, and node 2,3 and 4 switches to by seek mode.Node 1 such as can continue the pattern being maintained at main device, but the present embodiment is not limited to this, and now, as shown in Figure 4 C, node 2,3 and 4 respectively has effective range 404,406 and 408.
Then, the node 5 and 6 and the node 2 that are arranged in effective range 404 match, and the node 7 being arranged in effective range 406 will match with node 3.Now, node 2,5 and 6 is by formation microgrid, and node 3 and 7 then forms another microgrid.After completing pairing, node 5,6 and 7 will switch to main device, and switch to can by seek mode.
