In BLE, the messages are divided into broadcast messages and data messages, and devices in the bluetooth communication network discover and connect other devices by using the broadcast messages, and once connection is established, use of the data messages is started. Data messages can only be understood by two devices (master and slave) in the connection, while broadcast messages can be broadcast to multiple listening devices or sent only to a particular device. Whether the message is a broadcast message or a data message is determined by a channel where the message is transmitted, wherein BLE prescribes 3 broadcast channels and 37 data channels, if the message is transmitted on the broadcast channel, the message is a broadcast message, and if the message is transmitted on the data channel, the message is a data message.
Optionally, the first data packet is divided into a preamble part, an access address part (i.e. a first destination address), a PDU (Protocol Data Unit ) part and a CRC (Cyclic Redundancy Check, cyclic redundancy check) part.
Alternatively, the respective master devices may be devices of different functions, such as a bulb, thermometer, switch, etc.
Further, after the target master device receives the first data packet including the first target address through the data channel, the target master device may determine and execute the following operation according to the first target address.
Step 202A, when the first destination address is the network address of the target host device, executing a corresponding function according to the first data packet.
When the first target address is the network address of the target master device, it is indicated that the instruction information transmitted by the gateway device is specific to the target master device, so that the target master device executes the corresponding function according to the instruction information in the first data message. The instruction information may be issued by the user through the gateway device, and the corresponding function may be a function of the target host device itself, for example, the target host device is a light bulb, and then the light bulb lighting function may be performed.
Step 202B, when the first destination address is not the network address of the target master device, forwarding the first data packet to the corresponding target slave device according to the first destination address.
When the first target address is not the network address of the target master device, it is indicated that the instruction information transmitted by the gateway device is not specific to the target master device, so that the target master device forwards the first data message to the corresponding target slave device according to the first target address, and the target slave device performs an operation according to the first data message.
Alternatively, the at least one slave device may be a device of a different function, such as a bulb, thermometer, switch, etc.

Fig. 5 is a flow chart illustrating a method of bluetooth communication according to an exemplary embodiment. The method is performed jointly by a target master device, a target slave device and a gateway device in a messaging network as described in fig. 1. As shown in fig. 5, the bluetooth communication method may include the steps of:
in step 501, the gateway device sends a first data packet to the target host device according to the first target address.
The first data message includes the first target address.
A Gateway (Gateway), also known as Gateway, protocol converter, is a "Gateway" where one network connects to another network. The gateway device is responsible for maintaining all device connections in the bluetooth communication network, managing connections between all devices in the bluetooth communication network, e.g. adding device connections, deleting device connections, scanning for discovery devices. The gateway device can monitor wireless signals, judge whether there is a connectable device, establish a connection relationship by exchanging negotiation parameters with the connectable device, and establish a new transfer line in the bluetooth communication network. Fig. 6 is a schematic diagram of an operation process of a gateway device according to an embodiment of the present application, in which a child device, that is, each device that can be managed by the gateway device, MQTT (Message Queuing Telemetry Transport, message queue telemetry transport) is a message transmission protocol based on a publish/subscribe mode of a client server architecture.
In an actual application scenario, when a user needs to make a certain device (a target master device or a target slave device) in the bluetooth communication network execute a certain function, the user may connect with the bluetooth communication network through a terminal device, for example, a mobile phone or a computer with a bluetooth function, and issue an instruction through corresponding use software (for example, APP), where the instruction includes address information (a first target address) of the target device and information for executing a related function. After receiving the instruction of the user, the gateway device sends a first data message to the target main device according to the first target address, where the target main device is not necessarily the device where the first target address is located, but the device where the first target address is located has a complete transmission line with the target main device in the bluetooth communication network, for example, the device where the first target address is located in the slave device of the target main device, or the device where the first target address is located in the slave device of the next hop of the slave device of the target main device.
In step 502, the target host device receives a first data packet sent by the gateway device according to a first target address.
Optionally, each master device and each slave device has a routing function, and each master device and each slave device contains a routing table. Routing is the process of determining how devices communicate with each other between different networks, i.e. the activity of transmitting information from a source address to a destination address over an interconnected network. By using the routing table, each master device and each slave device can plan a transfer line to the device where the respective target address is located. When each master device and each slave device plan a transfer line to the device where the respective target address is located, a transfer line with the lowest number of hops (i.e., the shortest transfer line) is selected.
In step 503A, when the first destination address is the network address of the target host device, a corresponding function is executed according to the first data packet.
Optionally, the target host device parses the first data packet to obtain a first instruction.
Further, the target host device performs at least one of scanning the new device, connecting the new device, disconnecting the new device from the device, and performing a function preset by the target host device according to the first instruction.
In step 503B, when the first destination address is not the network address of the target master device, the first data packet is forwarded to the corresponding target slave device according to the first destination address.
Optionally, the target master device includes a first routing table. After receiving a first data message sent by the gateway device according to a first target address, the target master device can query the first routing table according to the first target address, determine a target slave device corresponding to the first target address, and forward the first data message to the target slave device corresponding to the first target address.
In step 504, the target slave device receives the first data packet forwarded by the target master device according to the first target address.
Optionally, the target slave device is the last device of the transfer line, that is to say the target slave device has no next hop slave device.
Optionally, the target slave device has a slave device of the next hop, and the target slave device is further connected with at least one slave device bluetooth.
In step 505A, when the first target address is the network address of the target slave device, a corresponding function is executed according to the first data packet.
