In legend, bluetooth radio communication system 30 comprises a main frame 32 and a plurality of terminating machine 34, described a plurality of terminating machine 34 has terminating machine A 3402, terminating machine B 3404 and terminating machine C 3406, all has bluetooth communication module respectively on main frame 32 and the terminating machine 34, to realize the function of short-distance wireless communication to each other.
Please further consult Fig. 2, Fig. 2 is the schematic diagram of main frame 32 of the present invention and 34 transfer of data of terminating machine.After main frame 32 and these terminating machine 34 communication link, at first by main frame 32 selected Bluetooth address 40, according to Bluetooth address 40 to consult a frequency hop sequences 42; Described frequency hop sequences 42 is the order of institute's frequency hopping in a plurality of channels (Channel) 44.
The Bluetooth address 40 that present embodiment is selected adopts a sign that is used as broadcasting required Bluetooth address 40 in the reservation hurdle (0x9E8B00-0x9E8B3F) among the LAP in the bluetooth address.According to Bluetooth address 40, see through an algorithm, promptly be called the sequence that original frequency hopping sequencer is produced by one in the LMP Link Manager Protocol (LMP), negotiate frequency hop sequences 42.
Carry out communication link by 79 channels 44 between bluetooth communication module,, be divided into many individual independently physical networks and carry out transfer of data according to the frequency hop sequences 42 of these 79 channels 44; 34 of main frame 32 and terminating machines can be according to the frequency hop sequences 42 of a specific negotiation, and frequency modulation is with the transmission data on 79 channels 44.
Ethernet also has the agreement of similar broadcasting or multicast in fact, and different is that Ethernet is to distinguish by destination address.In bluetooth of the present invention, the settling mode of definition frequency hop sequences 42 is to distinguish by original address, just leans on the selected Bluetooth address 40 of main frame 32, negotiates frequency hop sequences 42.
Main frame 32 is according to frequency hop sequences 42, and the package that transmits data according to the order of time shaft gives these channels 44.A plurality of terminating machines 34 in the legend still are terminating machine A 3402, terminating machine B 3404 and terminating machine C 3406, and these terminating machines 34 see through these channels 44 and main frame 32 communication link.Frequency hop sequences 42 is as being channel 01, channel 08, channel 72, channel 36 according to time sequencing among the figure These terminating machines A 3402, B 3404, C 3406 be according to frequency hop sequences 42, according to seasonal effect in time series channel 44 orders, and the synchronous package that receives data from these channels 44.
