The embodiment provides a Bluetooth device control method. Fig. 1 is a flowchart of a bluetooth device control method according to an embodiment of the present application, applied to a client, and as shown in fig. 1, the flowchart includes the following steps:
And 120, carrying out network distribution on the Bluetooth equipment according to the network distribution information, and activating and registering the Bluetooth equipment to a cloud server.
determining a content length of the broadcast packet;
according to the content length and the preset length of the broadcast packet, performing packet processing on the broadcast packet to obtain at least two broadcast packets;
at least two of the broadcast packets are cross-transmitted.
Conventionally, a bluetooth control device generally needs a chip for establishing a bluetooth channel, scans a received bluetooth broadcast sent by a bluetooth device through a bluetooth module based on a bluetooth protocol, identifies device information of the corresponding bluetooth device according to the received bluetooth broadcast, where the device information includes, but is not limited to, a device type, a device version, a device Mac address, and the like, establishes a bluetooth connection with the identified bluetooth device, and establishes a bluetooth channel between the control device and the bluetooth device. That is to say, when a device having a bluetooth module, for example, an intelligent luminaire, is not connected, a bluetooth broadcast is periodically transmitted, the control device scans the bluetooth broadcast around the control device through the bluetooth module, when the bluetooth broadcast of a new device is scanned, the device type, the device version, and the device Mac address of the bluetooth device corresponding to the bluetooth broadcast are identified, a bluetooth channel between the control device and the bluetooth device is established according to the received broadcast, and the control information transmitted by the control device is received through the bluetooth channel to execute a corresponding control operation. The method needs the Bluetooth equipment to send broadcast in the process of controlling the equipment through the Bluetooth, a client scans the broadcast of the Bluetooth equipment to establish Bluetooth connection, and the Bluetooth control is realized by receiving and sending data through the Bluetooth connection. However, on one hand, the method has the advantages that the chip price is high due to the chip manufacturing for establishing the Bluetooth connection, the cost and the like, and the competitive advantage is not provided for some commodities sensitive to the price; on the other hand, the bluetooth connection process is time consuming and may fail; and if the bluetooth equipment is connected all the time, the power consumption is higher.
According to the method and the device, the control instruction for controlling the Bluetooth equipment is broadcasted in the form of the broadcast packet, so that the Bluetooth equipment can be directly communicated with the client, a Bluetooth connection process is not needed, and the power consumption is lower because the Bluetooth equipment is not based on a ble protocol; in addition, an expensive chip is not needed, and the cost is reduced. And secondly, group control can be realized in the later period by controlling the Bluetooth equipment in a mode of broadcasting the broadcast packet by the client, and the expansibility is better on the basis of low cost.
In addition, the broadcast packet in the application is generated by combining the client according to the control instruction and the identification information of the Bluetooth device to be controlled, so that the devices of the same type can be prevented from executing control operation after receiving the broadcast packet. The combination may be that one or more bytes in the broadcast packet are predefined to represent the control command, and the identification information may be placed in the header or other bytes of the broadcast packet. Specifically, after the bluetooth devices of the same type receive the broadcast packet, one of the methods is as follows: firstly, the identification information of the head is obtained to judge whether the identification information is matched with the head. And if the Bluetooth control command is matched with the Bluetooth control command, further analyzing the broadcast packet, acquiring the Bluetooth control command, and executing the control operation corresponding to the control command. Another way is: and directly analyzing the broadcast packet to obtain the identification information and the control instruction of the Bluetooth equipment, and determining whether to execute the control instruction or not through the identification information.
In this application, bluetooth equipment can be intelligent equipment such as intelligent lamps and lanterns, intelligent TV, refrigerator. The client may include one or more of a Personal Computer (PC), a tablet, a smart phone, and a wireless terminal. The client side can be provided with a control APP, preferably, a control instruction of a user is received through the APP, the control instruction and the identification information of the Bluetooth device are combined to generate a broadcast packet, and the broadcast packet is sent in a broadcast mode.
According to the method and the device, the response broadcast packet sent by the Bluetooth equipment is received, and the data obtained after the response broadcast packet is analyzed is returned to the control panel. And establishing broadcast communication through the client, and after sending out the broadcast packet, receiving the broadcast and keeping in an open state all the time. After the Bluetooth device triggers corresponding behaviors according to the received control instruction, a response broadcast packet is generated, and the control is replied successfully. And after receiving the response broadcast packet, the client analyzes the response broadcast packet to obtain response data, and returns the response data to the client panel. Through the bidirectional interaction process between the client and the Bluetooth device, the client can definitely know whether the sent control command is effectively executed or not. Further, if the response broadcast packet is not received within the preset time, the broadcast packet may be retransmitted to ensure that the bluetooth device may receive the broadcast packet. The Bluetooth device only executes the control instruction contained in the first broadcast packet to the same broadcast packet received within the preset time, and improves the accuracy of control over the Bluetooth device while improving the receiving of the broadcast packet by the Bluetooth device.
The method comprises the steps that a broadcast packet generated by a client comprises a sub-packet zone bit, and the sub-packet zone bit is used for identifying whether the broadcast packet has sub-packets or not; the transmitting the broadcast packet in a broadcast manner includes:
determining a content length of the broadcast packet;
according to the content length and a preset length, performing sub-packet processing on the broadcast packet to obtain at least two broadcast sub-packets;
at least two of the broadcast packets are cross-transmitted.
The iOS handset sends the broadcast with a format limitation on the length of the field, which must be 16bits or 128 bits. There may be LocalName and Service id fields in the broadcast packet. If the LocalName field is used alone, the length limit of the LocalName of the apple-phone is too short, and all information cannot be stored, so the embodiment splits the broadcast content into the LocalName and Service id. The Bluetooth broadcast generated by the client is divided into two parts of data, namely LocalName and Service id. The LocalName group is used for storing device identification information, such as a mac address, and is used for indicating a broadcast sent to which bluetooth device, and the Service id part is mainly used for transmitting a control instruction. The Service id also stores the version number, the command, the self-increment number, the sub-package and parameter and the broadcast crc operation. The commands comprise distribution network command reporting, network access success command reporting, unbinding command issuing, control command reporting and control command issuing.
According to the above description, in order to improve the communication efficiency, the LocalName part data is not encrypted, and the Service id part data is broadcasted after being encrypted by using the encryption key.
In addition, sometimes, due to the limitation of the length of the broadcast content, the content of the complete broadcast packet is too long and needs to be sent in a sub-packet mode, and according to the length of the content and the preset length, the broadcast packet is subjected to sub-packet processing to obtain at least two broadcast sub-packets, and the broadcast sub-packets are sent in a cross mode.
Cross-forwarding may be understood as cross-forwarding a plurality of broadcast packets to a bluetooth device, i.e. at least two broadcast packets are sent in turn. For example, the client needs to send a command to the bluetooth device once, but because the data packet is too long, the data packet is divided into two broadcast packets, p1 and p2, and then sent 10 times first p1, 10 times later p2, 10 times later p1, and 10 times later p2, so as to ensure that the bluetooth device receives the broadcast packet. It will be appreciated that the bluetooth device processes the data received only once, ignoring other duplicate data to ensure accurate control. The number of the client relapses may also be other values, such as 5, 6, 8, etc., and is not particularly limited.
In some embodiments, the configuring the bluetooth device according to the distribution network information and activating and registering to a cloud server includes:
uploading the distribution network information to a cloud server to complete the registration of the Bluetooth equipment in the cloud server;
acquiring broadcast decryption information, wherein the broadcast decryption information is generated by the cloud server responding to the distribution network information; the broadcast decryption information includes key information for communication with the bluetooth device; the key information comprises an encryption key and a corresponding decryption key;
and keeping receiving the Bluetooth broadcast in an opening state after the distribution network is successful.
After scanning a broadcast packet containing distribution network information sent by the bluetooth device in the initial state, the client acquires basic information of the bluetooth device, including but not limited to a Mac address, parameters, UUID, and the like of the bluetooth device. The Bluetooth authority is started, meanwhile, the Bluetooth equipment is distributed with a network, the distribution network information is uploaded to a cloud server, and the characteristic information generated by a cloud server is returned to the Bluetooth equipment after registration is activated, wherein the characteristic information comprises equipment information, an equipment communication encryption and decryption key and the like. After the distribution network is successful, the client and the equipment receive the broadcast and are always in an open state, so that the broadcast packet can be received.
The method comprises the following steps that a client receives a control instruction of a user, combines the control instruction with identification information of the Bluetooth equipment to generate a broadcast packet, and sends the broadcast packet in a broadcast mode, and the method comprises the following steps:
and receiving a control instruction of a user. The user can send the control instruction by triggering the control panel, and can also send the control instruction by a voice or text input mode. The specific manner is not limited.
Encrypting the control instruction according to an encryption key generated by the cloud server;
and combining the encrypted control command and the identification information of the Bluetooth equipment to generate a broadcast packet, and sending the broadcast packet in a broadcast mode.
The specific control process for the bluetooth device is as follows:
and after the client panel triggers the control command, the client encrypts the control command through the encryption key, puts the encrypted control command and the Mac address into a broadcast packet, and sends the broadcast through the client. The Bluetooth equipment receives a broadcast packet sent by a client within a certain range, and matches the instruction to be processed with the Mac address according to whether the instruction needs to be processed or not. The control instructions are processed by a decryption key in the bluetooth device. And triggering corresponding behaviors through the decrypted control instruction and returning the responded instruction to the client through the encryption key. The client receives the device broadcast packet and returns the data analyzed by the decryption key to the client panel.
In other embodiments, matching whether an instruction needs to be processed by Mac address includes at least the following two cases: (1) in the broadcast packet, the identification information of the Bluetooth device is placed in a plaintext byte, and the data of the byte is not encrypted. The control instruction part is arranged in the ciphertext byte, and the data of the byte is encrypted through the encryption key. After receiving the broadcast packet, the bluetooth device may first obtain the identification information from the plaintext byte portion, which is described in this application taking the identification information as the Mac address as an example. If the identification information is matched with the self information, the ciphertext part is further decrypted through the decryption key to obtain a control instruction, and the operation corresponding to the control instruction is executed. (2) All data in the broadcast packet are encrypted by using the encryption key, and after receiving the broadcast packet, the Bluetooth device decrypts the broadcast packet by using the corresponding decryption key to obtain the identification information and the control instruction. And determining whether the control instruction needs to be executed according to the identification information. Through encrypting the broadcast packet, can promote bluetooth control's security. In the present application, the first method is adopted, and only the control command is encrypted.
In some embodiments, the packetization flag bit may be located in a plaintext portion of the broadcast packet, and the client does not encrypt data of the flag bit, so that the communication duration may be reduced.
The embodiment also provides a bluetooth device control method, which is applied to a bluetooth device, and as shown in fig. 2, the process includes the following steps:
According to the Bluetooth control method, the control instruction for controlling the Bluetooth equipment is broadcast in the form of the broadcast packet, so that the Bluetooth equipment can be directly communicated with the client, a Bluetooth connection process is not needed, and the Bluetooth control method is not based on a ble protocol and has lower power consumption; in addition, an expensive chip is not needed, and the cost is reduced. And secondly, group control can be realized in the later period by controlling the Bluetooth equipment in a mode of broadcasting the broadcast packet by the client, and the expansibility is better on the basis of low cost.
In some of these embodiments, the method further comprises:
when the Bluetooth equipment actively updates information, the updating information is encrypted through an encryption key to generate an updating broadcast packet; sending the updating broadcast packet to the client;
and after receiving the updating broadcast packet, the client decrypts the updating broadcast packet by adopting a corresponding decryption key to obtain decrypted data, and synchronizes the decrypted data to a control panel of the client.
Since the control instruction is sent and then the control broadcast is relied on, the client state change in the application can be returned without depending on the device state for the user experience. The state of the equipment is actively synchronized, and the client does not need to send broadcast to inform the Bluetooth equipment after receiving the message, so that the synchronous control is realized.
The bluetooth device further comprises, after receiving the broadcast packet broadcasted by the client:
identifying the state of a sub-packet flag bit in the broadcast packet, and determining whether the broadcast packet is a broadcast sub-packet according to the state of the sub-packet flag bit;
if the broadcast packet is a broadcast sub-packet, acquiring the state of a sequence flag bit in the broadcast sub-packet;
and combining a plurality of broadcast sub-packets according to the state of the sequential flag bit of each broadcast sub-packet to obtain a complete broadcast packet.
Specifically, the bluetooth device judges whether the packet data is stored according to the packet flag bit in the service id. The state of the packetization flag may be specifically a number, for example, 0 indicates that it is not a broadcast packet, and 1 indicates that it is a broadcast packet. If the broadcast sub-packets exist, the Bluetooth equipment performs combination according to the receiving sequence of the broadcast packets. The broadcast packet contains SN bytes which are used as beacon frame serial numbers and occupy 4 bytes, the device resets each time and returns to zero, and the SN value is added with 1 when a different broadcast packet is sent each time; the SN remains consistent with each retransmission or forwarding. If the SN is not 0 or is sub-packaged, the broadcast is known to be terminated when the SN is 0 in the last packet, the sequence of the broadcast sub-packages can be known according to the SN, and the broadcast sub-packages are combined according to the sequence to obtain a complete broadcast packet.
For better explanation of the bluetooth device control method provided in the present application, refer to the interaction diagram of fig. 3.
After a client (including but not limited to a mobile phone, a tablet, a computer, etc.) scans a bluetooth device (hereinafter referred to as "device") which is in an initial state and sends out distribution network broadcast, basic information of the device is acquired. (including but not limited to Mac addresses, parameters, UUIDs, etc.). The Bluetooth permission is opened, the equipment is distributed, the broadcast information is uploaded to the cloud end, and the characteristic information is returned to the equipment end after registration is activated, such as equipment information, equipment communication encryption and decryption keys and the like. After the distribution network is successful, the client and the equipment end receive the broadcast and are always in an open state. After the client panel triggers the control command, the client encrypts the control command through the encryption key, puts the encrypted control command and the Mac address into a broadcast packet, and sends the broadcast through the client. The device receives the broadcast packet sent by the client within a certain range, and matches the instruction to be processed with the Mac address according to whether the instruction is the instruction to be processed or not. The device instructions are processed by a decryption key in the device. And triggering corresponding behaviors through the decrypted device instruction and returning the responded instruction to the client through the encrypted key. And the client receives the device broadcast packet and returns the data analyzed by the decryption key to the client panel. And when the equipment actively updates the information, the broadcast packet is sent after the encryption by the encryption key. And after receiving the broadcast, the client analyzes the data through the decryption key and synchronizes the information to the client panel.
