Then the compression encryption of above-mentioned configuration parameter is packed into CTP data packet by main earphone, then main earphone selection it is high,
In, three, bottom broadcast channel, if channel 3, channel 35 and channel 75 carry out CTP data packet broadcast transmission, send CTP number
When according to packet broadcast, regardless of main earphone is the main equipment or Bluetooth slave devices in network, main earphone all can be in MS master-slave time slot
The time starting point of (Master-to-Slave time slot) is broadcasted on a channel in high, medium and low.CTP broadcasts it
Afterwards, main earphone is by the time point of next time slot, i.e., from-main slot time starting point, tastes on same broadcast channel
Reply data packet of the receipts of trying from earphone.The broadcast channel of main earphone will be cut after not receiving the reply data packet from earphone
It changes, the selection for broadcast channel, the present channel of main earphone is necessarily different from preceding selection twice.Such as, preceding to be respectively twice
Channel 3 and channel 75, then current broadcast channel is 35, subsequent selection, in the present embodiment, according to channel 3,
Channel 75, channel 35 sequence successively switch.
As shown in Figure 1, main earphone starts to broadcast CTP data packet in the start time point of MS master-slave time slot first in channel 3,
Then in the time starting point from-main time slot, the reply data packet (ACK) whether having from earphone is equally received on channel 3.By
In, not from the reply of earphone, after terminating from-main time slot, main earphone broadcasts CTP on next channel 75 on channel 3
Data packet.Still not from the reply of earphone on channel 75, after 2 slot times, main earphone broadcasts CTP in channel 35
Data packet finally receives the reply data packet (ack msg packet) from earphone from-main time slot in channel 35.
In this process, the CTP number for whether having main earphone scanned to poll on high, medium and low three channels from earphone
According to packet broadcast.It is identical with main earphone for the selection of broadcast channel, i.e., must be not used in from the channel of the next selection of earphone
Preceding selection twice.It is channel 3 and channel 75 respectively twice as preceding, then current broadcast channel is 35.Subsequent selection according to
It is secondary to analogize.It is greater than the duration of 6 time slots, at least from the scanning duration of earphone each channel to guarantee to scan each time at least
Once on the same channel with main earphone.Duration of its interval time scanned at least more than the scanning of each channel.Root
According to considering for power consumption and Connection Time, scan duration and sweep interval can be by situation depending on.
In channel 35, at this time from earphone just in this scan channel, it has received the CTP broadcast packet that main earphone is sent
Data.Since main earphone is to send data in MS master-slave time slot, therefore after receiving CTP data packet, main earphone will be obtained from earphone
The necessary information of blueteeth network between mobile phone.In channel 35 from-main time slot, complex data packet is sent back to main earphone from earphone
To indicate that its data receiver is completed.
In main earphone and after the reception that earphone completes CTP data packet, join from earphone according to the configuration in CTP data packet
Number data are added in blueteeth network, and the audio output synchronous with main earphone is realized from the audio data of headphone monitor mobile phone.
Specifically, when sending director data: the method that instruction is transmitted between following bluetooth equipment is executed, this method comprises:
S2100: the main receiving device of bluetooth sends normal data packet to source data equipment；
S2200: the main receiving device of bluetooth sends director data packet within the free time of the same time slot；
S2300: source data equipment receives normal data packet and director data packet, is detected by filtering by director data packet
It abandons；Bluetooth time receiving device also receives director data packet；
S2400: source data equipment sends normal data packet in next time slot；
S2500: the main receiving device of bluetooth and bluetooth time receiving device receive the criterion numeral that source data equipment is sent simultaneously
According to packet；
S2600: bluetooth time receiving device sends director data packet after receiving；
S2700: the main receiving device of bluetooth receives the director data packet of bluetooth time receiving device, completes the main reception of bluetooth and sets
Standby and bluetooth is transmitted from the instruction between receiving device.
The total length of bluetooth data packets is converted into sending time, from the point of view of time slot, there is 3 seed types: when occupying 1
Gap, 3 time slots or 5 time slots.From Bluetooth specification, we can sum up ACL and S2CO two major classes data packet format,
And the corresponding number of timeslots of specific every one kind, it is as shown in Table 1:
Table one:
| Number of timeslots | S2CO/eS2CO data packet | ACL data packet |
| 1 | HV1,HV2,HV3,EV3,2-EV3,3-EV3 | DM1,DH1,2-DH1,3DH1,AUX1 |
| 3 | EV4,EV5,2EV5,3EV5 | DM3,2-DH3,DH3,3-DH3 |
| 5 | N/A | DM5,2-DH5,DH5,3-DH5 |
The data packet of bluetooth is divided into basic rate (BDR) and enhancing rate (EDR) two type from the point of view of transmission rate
Type.Since basic rate (BDR) data packet all uses GFS2K to modulate, and its chip rate (S2ymbol rate) is
1MbpS2, thus the transmission time of basic rate (BDR) data packet on numerical value (unit uS2) be equal to it includes bit quantity.
If data (including acceS2S2 code, header and payload) sending time of 800bit is 800uS2.Enhancing
In rate (EDR) data packet, AcceS2S2 Code and Header are modulated using GFS2K mode, chip rate 1MbpS2；
S2YNC, Payload and Trailer using DPS2K modulate, chip rate 1MbpS2, symbol can be 2bit or
3bit (more depending on concrete type).In addition, also including a Guard Time, time in enhancing rate (EDR) data packet
Probably in 5uS2 or so.Since S2YNC and TRAILER length is fixed in enhancing rate (EDR) data packet, transmission time is respectively
11uS2 and 2uS2, we can will enhance the additional load (EDR extra loading) of rate (EDR) data packet and calculate
Are as follows: GUARD+S2YNC+TRAILER=5+11+2=18 (uS2).
It is analyzed based on above, if it is considered that the maximum PAYLOAD of the specific data packet of each type, while whether packet being had
FEC, MIC, CRC also take into account, we can calculate the maximum transmission time of every kind of data packet, while having more it
For S2lot quantity, the remaining free time after every kind of data packet is sent completely can be calculated.
As a result as shown in following table two and table three, it is not difficult to find out that the data packet of DM3 type remaining free time is minimum.It is based on
This, we it is concluded that: we can allow between bluetooth equipment and transmit our needs in at least gap of 189uS2
Data and order.
