[0100] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0101] In the related art, MQTT is usually used for data transmission, but MQTT uses TCP as the transport layer protocol, which will cause certain network resource consumption. In order to solve the above technical problems, the present invention provides a communication method, a protocol gateway establishes a Bluetooth connection with a first terminal device, allocates account information to the first terminal and sends the account information to the first terminal device, then disconnects the Bluetooth connection with the first terminal device, and then receives a connection request of a preset communication protocol sent by the first terminal device via Bluetooth broadcast, wherein the connection request of the preset communication protocol includes account information, responds to the connection request of the preset communication protocol, and thus can establish a communication connection of the preset communication protocol with the first terminal device according to the account information, and finally sends the control command of the preset communication protocol to the first terminal device via blue sky broadcast, so that the first terminal device responds to the control command of the preset communication protocol after receiving the control command of the preset communication protocol, so that the protocol gateway can establish a communication connection of the preset communication protocol with the first terminal device, and send the control command of the preset communication protocol via Bluetooth broadcast, because the control command of the preset communication protocol is transmitted by Bluetooth broadcast, the consumption of network resources is avoided, and efficient communication is guaranteed.

[0102] Reference Figure 1 , shows a flow chart of the steps of a communication method provided by an embodiment of the present invention, the method is applied to a protocol gateway, and the method may specifically include the following steps:

[0103] Step 101: Establish a Bluetooth connection with a first terminal device.

[0104] In an embodiment of the present invention, the protocol gateway needs to establish a Bluetooth connection with the first terminal device before communicating with the first terminal device. In the present invention, the protocol gateway may be an MQTT gateway, and the first terminal device may be a Bluetooth device.

[0105] It should be noted that before the protocol gateway of the present invention establishes a Bluetooth connection with the first terminal device, the protocol gateway may first establish a Bluetooth connection with the second terminal device, and then obtain routing information sent by the second terminal, which may be routing information sent by a preset application deployed in the second terminal, and then the protocol gateway sends a registration request to the server according to the routing information, so that the server responds to the registration information and establishes a connection with the protocol gateway. The second terminal device in the present invention may be a mobile terminal, such as a mobile phone, a tablet, etc.

[0106] In one embodiment, the communication method may further include: generating a key, sending the key to a second terminal device, so that after the second terminal device establishes a connection with the first terminal device, the key is sent to the first terminal device; establishing a Bluetooth connection with the first terminal device may include: receiving a Bluetooth connection request sent by the first terminal device, and responding to the Bluetooth connection request sent by the first terminal device to establish a Bluetooth connection with the first terminal device; after the first terminal device receives the key, the Bluetooth connection request disconnects the connection with the second terminal device and sends the Bluetooth connection request to the protocol gateway.

[0107] Specifically, after the protocol gateway establishes a connection with the server, a key can be generated, which can be a created random string. The generated key is then sent to the second terminal device. After the first terminal device and the second terminal device are connected via Bluetooth, the second terminal device can send the key to the first terminal device. After receiving the key, the first terminal device will disconnect the Bluetooth connection with the second terminal device. Then the first terminal device can send a Bluetooth connection request to the protocol gateway. After receiving the Bluetooth connection request, the protocol gateway can establish a Bluetooth connection with the first terminal device.

[0108] Step 102: Allocate account information to the first terminal device and send the account information to the first terminal device.

[0109] In an embodiment of the present invention, after the protocol gateway establishes a Bluetooth connection with the first terminal device, account information can be allocated to the first terminal device, and the account information may be usename, password, etc., and then the protocol gateway sends the account information to the first terminal device.

[0110] In one embodiment, allocating account information to a first terminal device and sending the account information to the first terminal device may include: determining the account information; encrypting the account information using a key to obtain encrypted account information; and sending the encrypted account information to the first terminal device so that the first terminal device decrypts the encrypted account information according to the key to obtain the account information.

[0111] Specifically, for example, if the key is key A, after the protocol gateway determines the account information, it can encrypt the account information through key A to obtain encrypted account information, and then send the encrypted account information to the first terminal device. The first terminal device decrypts the encrypted account information through key A to obtain the account information, so that the data can be protected by key A, effectively preventing the leakage of account information.

[0112] Step 103: disconnect the Bluetooth connection with the first terminal device.

[0113] In the embodiment of the present invention, after sending the account information to the first terminal device, the protocol gateway may disconnect the Bluetooth connection with the first terminal device.

[0114] Step 104: receiving a connection request of a preset communication protocol sent by the first terminal device via Bluetooth broadcast; the connection request of the preset communication protocol includes the account information.

[0115] In an embodiment of the present invention, after the protocol gateway disconnects the Bluetooth connection with the first terminal device, the first terminal device sends a connection request of a preset communication protocol via Bluetooth broadcast. In the present invention, the preset communication protocol may be the MQTT protocol. The connection request of the preset communication protocol may include account information.

[0116] For example, after the protocol gateway disconnects the Bluetooth connection with the first terminal device, the first terminal device broadcasts a connect packet using Bluetooth and waits for a connect ack reply from the protocol gateway. After receiving the connect ack reply from the protocol gateway, the first terminal device can communicate with the protocol gateway using a preset communication protocol.

[0117] Step 105 , responding to the connection request of the preset communication protocol, and establishing a communication connection of the preset communication protocol with the first terminal device according to the account information.

[0118] In an embodiment of the present invention, after receiving a connection request for a preset communication protocol sent by the first terminal via Bluetooth broadcast, the protocol gateway can respond to the connection request for the preset communication protocol, and when the account information meets the preset requirements, or when the account information is previously generated account information, a communication connection for the preset communication protocol can be established with the first terminal device.

[0119] In one embodiment, responding to a connection request of a preset communication protocol, establishing a communication connection of the preset communication protocol with the first terminal device according to the account information includes: responding to the connection request of the preset communication protocol, sending a registration request to the server according to the account information; receiving a registration success message returned by the server according to the registration request, and establishing a communication connection of the preset communication protocol with the first terminal device.

[0120] Specifically, after receiving a connection request for a preset communication protocol sent by the first terminal device via Bluetooth broadcast, the protocol gateway can send a registration request to the server based on the account information so that the account information of the first terminal device is stored in the server. The server can then send control information to the first terminal device based on the account information. After the server registration is successful, a registration success message can be returned to the protocol gateway. After receiving the registration success message, the protocol gateway can establish a communication connection of the preset communication protocol with the first terminal device.

[0121] In the present invention, after the first terminal device establishes a communication connection with the protocol gateway using a preset communication protocol, it can use Bluetooth broadcast to subscribe to the corresponding topic and report the relevant status. After the server registration is successful, a registration success message can be sent to the second terminal device, and the terminal device can display the corresponding second terminal device as being in an activated state.

[0122] Step 106: Send the control command of the preset communication protocol to the first terminal device via Bluetooth broadcast, so that the first terminal device responds to the control command of the preset communication protocol after receiving the control command of the preset communication protocol.

[0123] In an embodiment of the present invention, after the protocol gateway establishes a communication connection of a preset communication protocol with the first terminal device, the protocol gateway can send a control command of the preset communication protocol to the first terminal device via Bluetooth broadcast. After the first terminal device receives the control command of the preset communication protocol, it can respond to the control command of the preset communication protocol.

[0124] In one embodiment, a control command of a preset communication protocol is sent to a first terminal device via Bluetooth broadcast, including: obtaining control information sent by a server; the control information is sent by a second terminal device to the server; the control information is converted into a control command of a preset communication protocol, and the control command of the preset communication protocol is sent to the first terminal device via Bluetooth broadcast.

[0125] Specifically, when the user needs to control the first terminal device, the user can send relevant control information to the server through the second terminal device. After receiving the control information, the server can send the control information to the protocol gateway. The protocol gateway can convert the control information into a control command of a preset communication protocol, and then send the control command of the preset communication protocol to the first terminal device via Bluetooth broadcast, thereby controlling the first terminal device through the second terminal device.

[0126] In an embodiment of the present invention, after the protocol gateway establishes a communication connection of a preset communication protocol with the first terminal device, the first terminal device can send heartbeat information of the preset communication protocol to the protocol gateway at a first preset frequency. After the protocol gateway receives the heartbeat information sent by the first terminal device, it can return a corresponding heartbeat response to the first terminal device, thereby ensuring continuous connection and communication between the first terminal and the protocol gateway.

[0127] In order to better understand the embodiments of the present invention, Figure 2 As shown, another communication method provided by an embodiment of the present invention is shown. The second terminal establishes a Bluetooth connection with the protocol gateway and transmits routing information to the protocol gateway. The protocol gateway establishes a connection with the server according to the routing information. The protocol gateway generates a key and sends the key to the second terminal, and then the broadcast can be released again to wait for the identification connection. After the second terminal receives the key, it can establish a Bluetooth connection with the first terminal device. After the connection is successful, the key can be sent to the first terminal device. After receiving the key, the first terminal device can disconnect the Bluetooth connection with the second terminal. After the first terminal disconnects the Bluetooth connection with the second terminal, it can establish a Bluetooth connection with the protocol gateway. Then the protocol gateway can allocate account information to the first terminal device and encrypt the account information based on the key. The first terminal device can use the key to decrypt the encrypted account information to obtain the account information. Then the first terminal device disconnects the Bluetooth connection with the protocol gateway and sends a connection request of the preset communication protocol to the protocol gateway through Bluetooth broadcast. After receiving the connection request of the preset communication protocol, the protocol gateway will register the account information of the first terminal device to the server. After the registration is successful, the protocol gateway can establish a communication connection of the preset communication protocol with the first terminal device.

[0128] In an embodiment of the present invention, a Bluetooth connection is established with a first terminal device; account information is allocated to the first terminal device and the account information is sent to the first terminal device; the Bluetooth connection with the first terminal device is disconnected; a connection request of a preset communication protocol sent by the first terminal device via Bluetooth broadcast is received; the connection request of the preset communication protocol includes account information; the connection request of the preset communication protocol is responded to, and a communication connection of the preset communication protocol is established with the first terminal device according to the account information; a control command of the preset communication protocol is sent to the first terminal device via Bluetooth broadcast, so that the first terminal device responds to the control command of the preset communication protocol after receiving the control command of the preset communication protocol. Thus, the protocol gateway can establish a communication connection of the preset communication protocol with the first terminal device, and send the control command of the preset communication protocol via Bluetooth broadcast. It is precisely because the control command of the preset communication protocol is transmitted by Bluetooth broadcast that the consumption of network resources is avoided and efficient communication is guaranteed.

[0129] like Figure 3FIG. 1 is a flowchart of another communication method provided by an embodiment of the present invention. The method is applied to a first terminal device and may specifically include the following steps:

[0130] Step 301: Establish a Bluetooth connection with a protocol gateway.

[0131] In an embodiment of the present invention, the protocol gateway needs to establish a Bluetooth connection with the first terminal device before communicating with the first terminal device. In the present invention, the protocol gateway may be an MQTT gateway, and the first terminal device may be a Bluetooth device.

[0132] It should be noted that before the protocol gateway of the present invention establishes a Bluetooth connection with the first terminal device, the protocol gateway may first establish a Bluetooth connection with the second terminal device, and then obtain routing information sent by the second terminal, which may be routing information sent by a preset application deployed in the second terminal, and then the protocol gateway sends a registration request to the server according to the routing information, so that the server responds to the registration information and establishes a connection with the protocol gateway. The second terminal device in the present invention may be a mobile terminal, such as a mobile phone, a tablet, etc.

[0133] In one embodiment, establishing a Bluetooth connection with a protocol gateway may include: establishing a connection with a second terminal device and receiving a key sent by the second terminal device; after the key is generated by the protocol gateway, sending the key to the second terminal device; after receiving the key, disconnecting from the second terminal device and sending a Bluetooth connection request to the protocol gateway, so that the protocol gateway receives the Bluetooth connection request sent by the first terminal device, responds to the Bluetooth connection request sent by the first terminal device, and establishes a Bluetooth connection with the first terminal device.

[0134] Specifically, after the protocol gateway establishes a connection with the server, a key can be generated, which can be a created random string. The generated key is then sent to the second terminal device. After the first terminal device and the second terminal device are connected via Bluetooth, the second terminal device can send the key to the first terminal device. After receiving the key, the first terminal device will disconnect the Bluetooth connection with the second terminal device. Then the first terminal device can send a Bluetooth connection request to the protocol gateway. After receiving the Bluetooth connection request, the protocol gateway can establish a Bluetooth connection with the first terminal device.

[0135] Step 302, receiving the account information sent by the protocol gateway; the account information is allocated by the protocol gateway to the first terminal device.

[0136] In an embodiment of the present invention, after the protocol gateway establishes a Bluetooth connection with the first terminal device, account information can be allocated to the first terminal device, and the account information may be usename, password, etc., and then the protocol gateway sends the account information to the first terminal device.

[0137] In one embodiment, receiving account information sent by a protocol gateway may include: receiving encrypted account information sent by the protocol gateway; after the protocol gateway determines the account information, encrypting the account information with a key to obtain the encrypted account information; and decrypting the encrypted account information according to the key to obtain the account information.

[0138] Specifically, for example, if the key is key A, after the protocol gateway determines the account information, it can encrypt the account information through key A to obtain encrypted account information, and then send the encrypted account information to the first terminal device. The first terminal device decrypts the encrypted account information through key A to obtain the account information, so that the data can be protected by key A, effectively preventing the leakage of account information.

[0139] Step 303: disconnect the Bluetooth connection with the protocol gateway.

[0140] In the embodiment of the present invention, after receiving the account information sent by the protocol gateway, the first terminal device may disconnect the Bluetooth connection with the protocol gateway.

[0141] Step 304: A connection request of a preset communication protocol is sent to the protocol gateway via Bluetooth broadcast, so that the protocol gateway responds to the connection request of the preset communication protocol and establishes a communication connection of the preset communication protocol with the first terminal device according to the account information; the connection request of the preset communication protocol includes the account information.

[0142] In an embodiment of the present invention, after the first terminal device disconnects the Bluetooth connection with the protocol gateway, the first terminal device sends a connection request of a preset communication protocol via Bluetooth broadcast. In the present invention, the preset communication protocol may be the MQTT protocol. The connection request of the preset communication protocol may include account information.

[0143] After receiving a connection request for a preset communication protocol sent by the first terminal via Bluetooth broadcast, the protocol gateway can respond to the connection request for the preset communication protocol and establish a communication connection for the preset communication protocol with the first terminal device when the account information meets the preset requirements or the account information is previously generated account information.

[0144] Step 305: Acquire the control command of the preset communication protocol sent by the protocol gateway via Bluetooth broadcast, and respond to the control command of the preset communication protocol.

[0145] In the embodiment of the present invention, after the protocol gateway establishes a communication connection of the preset communication protocol with the first terminal device, the protocol gateway can send the control command of the preset communication protocol to the first terminal device through Bluetooth broadcast, and after the first terminal device receives the control command of the preset communication protocol, it can respond to the control command of the preset communication protocol. The control command of the preset communication protocol is obtained by the protocol gateway obtaining the control information sent by the server and converting the control information; the control information is sent to the server by the second terminal device.

[0146] Specifically, when the user needs to control the first terminal device, the user can send relevant control information to the server through the second terminal device. After receiving the control information, the server can send the control information to the protocol gateway. The protocol gateway can convert the control information into a control command of a preset communication protocol, and then send the control command of the preset communication protocol to the first terminal device via Bluetooth broadcast, thereby controlling the first terminal device through the second terminal device.

[0147] In an embodiment of the present invention, a Bluetooth connection is established with a first terminal device; account information is allocated to the first terminal device and the account information is sent to the first terminal device; the Bluetooth connection with the first terminal device is disconnected; a connection request of a preset communication protocol sent by the first terminal device via Bluetooth broadcast is received; the connection request of the preset communication protocol includes account information; the connection request of the preset communication protocol is responded to, and a communication connection of the preset communication protocol is established with the first terminal device according to the account information; a control command of the preset communication protocol is sent to the first terminal device via Bluetooth broadcast, so that the first terminal device responds to the control command of the preset communication protocol after receiving the control command of the preset communication protocol. Thus, the protocol gateway can establish a communication connection of the preset communication protocol with the first terminal device, and send the control command of the preset communication protocol via Bluetooth broadcast. It is precisely because the control command of the preset communication protocol is transmitted by Bluetooth broadcast that the consumption of network resources is avoided and efficient communication is guaranteed.
