Fig. 3 is the home network schematic diagram of the network-building method based on bluetooth.
Embodiment
The embodiment of the present invention is described in more detail below in conjunction with the accompanying drawings.
Embodiment one, in the network-building method based on bluetooth of the present embodiment include two processes, when networking process, second,
Data transmission procedure.
Networking process refers to the process of that the bluetooth equipment of mobile terminal and surrounding forms a network, and the mobile terminal is
Refer to mobile phone, flat board, blue Tooth remote controller, notebook computer or Intelligent worn device with Bluetooth function etc., the bluetooth equipment
Including bluetooth earphone, Intelligent worn device, Bluetooth adapter, bluetooth warner or intelligent home device etc..Data transmission procedure
Refer to the process of mobile terminal and the bluetooth equipment transmission data in network.
Shown in Figure 1, networking process concretely comprises the following steps：
Step 101：Bluetooth equipment around mobile terminal to search.
Mobile terminal enters search pattern, searches for the bluetooth equipment of surrounding, and step is entered after bluetooth equipment is searched
102。
Step 102：Mobile terminal is authenticated to bluetooth equipment.
Mobile terminal exchanges Bluetooth address with bluetooth equipment first, and then mobile terminal generation encryption key is sent to bluetooth
Equipment, complete authentication process.
Step 103：Mobile terminal generates id information, sends to bluetooth equipment.
Mobile terminal generates id information, and the id information of generation is sent into bluetooth equipment, i.e. mobile terminal is set to bluetooth
It is standby to be assigned with an id information, so as to complete the networking process of mobile terminal and the bluetooth equipment.Id information is that the bluetooth is set
Standby mark in a network.
If there are other bluetooth equipments to need to add network, repeat step 102 and 103.
It is different that the id information of each bluetooth equipment is distributed to due to mobile terminal, ensure that in consolidated network, often
The id information of individual bluetooth equipment is unique.In consolidated network, id information can be as the unique mark of bluetooth equipment.Encryption
Key is used for the encryption of data transmission procedure, and the bluetooth equipment only in consolidated network could receive data, ensure that data
The safety and reliability of transmitting procedure.In the present embodiment, encryption key is preferably 128bit.
In consolidated network, include mobile terminal and multiple bluetooth equipments.Mobile terminal and the bluetooth in consolidated network
The data transmission procedure of equipment comprises the following steps that：
Step 201：Start.
All bluetooth equipments in network are in scan pattern.
Step 202：Mobile terminal is established BLE with bluetooth equipment and is connected, and sends packet to the bluetooth equipment.
Mobile terminal chooses a bluetooth equipment in network, establishes BLE with it and is connected, the bluetooth equipment that this is chosen is by sweeping
It is transceiver mode to retouch pattern switching, and other bluetooth equipments are still in scan pattern.The bluetooth equipment that mobile terminal is chosen to this
Send packet.Packet includes device identifier id information, timestamp information, control information, check information etc..
Step 203：Bluetooth equipment received data packet.
Step 204：Bluetooth equipment judges whether it is to receive the packet first.
Timestamp information in packet, bluetooth equipment judge whether it is to receive the packet first.
If the bluetooth equipment is to receive the packet first, into step 205；
If the bluetooth equipment is not to receive the packet first, i.e. the bluetooth equipment has treated the packet,
Then enter step 209.
Step 205：Bluetooth equipment judges whether packet meets predetermined protocol.
The predetermined protocol can be the id information of bluetooth equipment of the id information with receiving the packet in packet
Unanimously.
If packet meets predetermined protocol, that is to say, that indigo plant of the id information with receiving the packet in packet
The id information of tooth equipment is consistent, illustrates that the packet is destined to the bluetooth equipment, then into step 208；
If packet does not meet predetermined protocol, that is to say, that the id information in packet is with receiving the packet
The id information of bluetooth equipment is inconsistent, illustrates that the packet is not destined to the bluetooth equipment, then into step 206.
Step 206：Broadcast data packet.
Bluetooth equipment switches to broadcast mode by transceiver mode, and data packet broadcast is gone out, i.e., bluetooth equipment is as one
Communication node relays away data.Bluetooth equipment switches to scan pattern after data packet broadcast is gone out, into step 207.
Step 207：Receive broadcast data packet.
Bluetooth equipment scanning in network switches to transceiver mode by scan pattern, receives broadcast to the packet of broadcast
Packet, return to step 204.
Step 208：Bluetooth equipment completes corresponding operation according to the control information in packet, and is sent to mobile terminal
Response message.
Bluetooth equipment receives the inverse path of the packet to the path of mobile terminal transmission response message for the bluetooth equipment.
For example, Fig. 3 is refer to, mobile terminal M（Mobile phone）N number of bluetooth equipment around is received after performing the networking process of step 101 to 103
Enter networking（Shown in solid circles）, then send with the bluetooth connection of bluetooth equipment 4 and to bluetooth equipment 4 and include the ID of bluetooth equipment 5
The packet of information, bluetooth equipment 4 judge that the packet is not that mobile phone is sent to oneself after performing step 205, therefore
Perform step 206 data packet broadcast is gone out（Shown in dotted line circle）, bluetooth equipment 1,2,3,5 ..., N receive bluetooth equipment 4
The packet of broadcast, the bluetooth equipment execution step 205 and 206 in addition to bluetooth equipment 5, the execution of bluetooth equipment 5 step 205,
208, to complete corresponding operating according to the control information of packet, then send response message, the response message of transmission is transmitted first
To bluetooth equipment 4, transmitted by bluetooth equipment 4 to mobile terminal M, thus terminate scanning of remaining bluetooth equipment to the packet
And broadcast, into the scan pattern state to next packet.
After bluetooth equipment has sent response message, scan pattern is switched to by transceiver mode.Into step 210.
Step 209：Do not deal with.
If the bluetooth equipment has treated packet, that is to say, that the bluetooth equipment had broadcasted the data
Wrap or the control information in packet completes corresponding operation, then the bluetooth equipment does not reprocess the data
Bag.Same bluetooth equipment is avoided to reprocess same packet.
Step 210：Terminate.
Predetermined protocol in the step 205 is not limited to the example above, can be formulated according to the actual requirements.Example
Such as, other identification informations are also included in the packet, predetermined protocol can be that other identification informations meet the requirements, bluetooth
Equipment judges whether packet meets predetermined protocol, that is, judges whether other identification informations meet the requirements, and according to judgement
As a result subsequent operation is carried out.
In the present embodiment, a bluetooth equipment has Three models：Scan pattern, broadcast mode, transceiver mode.Pass through
The switching of bluetooth equipment pattern, a bluetooth equipment is possessed three kinds of different functions, reduce further networking cost, and control
Mode simple and flexible processed.Bluetooth equipment can realize packet in network as the communication node broadcast data packet in network
In long range transmission.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the those of ordinary skill in domain is made in the essential scope of the present invention, should also belong to this hair
Bright protection domain.
