When the user equipment scans the broadcast signal with the second equipment information, the equipment connection information of the user equipment is sent to the Bluetooth gateway, and the connection information can comprise the user ID of the user equipment and the MAC address of the second equipment.
Step S203, receiving first information sent by a Bluetooth gateway, and creating a first service, wherein the first service sends a second broadcast signal, and the second broadcast signal carries the first information;
in this step, the user equipment receives first information sent by the bluetooth gateway, where the first information may be a key value, and is used by the gateway to determine the user equipment later. When receiving the first information, the user equipment creates a first service locally, the first service transmits a second broadcast signal, and the first information is carried in the second broadcast signal. The first service may be a gatt server, and the first information is the key value, so that the bluetooth gateway can conveniently use the key value to notify the user equipment when the bluetooth gateway schedules the user equipment.
Step S204, receiving a connection request of a Bluetooth gateway, wherein the Bluetooth gateway comprises a second service simulating second equipment;
in this step, the user equipment receives a connection request of the bluetooth gateway, and the connection request may include the first information in step S203 to confirm that the user equipment and the bluetooth gateway may be connected.

The embodiment of the disclosure provides a Bluetooth communication method and device based on gateway scheduling connection, electronic equipment and a computer readable storage medium. The Bluetooth communication method based on gateway scheduling connection comprises the following steps: scanning a first broadcast signal of a Bluetooth gateway, wherein the first broadcast signal is provided with information of second equipment; in response to scanning the first broadcast signal, sending connection information of a first device to the Bluetooth gateway; receiving first information sent by a Bluetooth gateway, and creating a first service, wherein the first service sends a second broadcast signal, and the second broadcast signal carries the first information; receiving a connection request of a Bluetooth gateway, wherein the Bluetooth gateway comprises a second service simulating second equipment; connecting to the second service on the Bluetooth gateway through Bluetooth. The embodiment of the disclosure solves the problem of monopolizing the Bluetooth equipment by scheduling and connecting the Bluetooth gateway, so that the user equipment which needs to be connected with the Bluetooth equipment can be connected to the required Bluetooth equipment in time.
Fig. 3 is a flowchart of a first embodiment of a bluetooth communication method based on a gateway scheduling connection according to an embodiment of the present disclosure, where the bluetooth communication method based on the gateway scheduling connection according to this embodiment may be executed by a bluetooth communication apparatus based on the gateway scheduling connection, and the bluetooth communication apparatus based on the gateway scheduling connection may be implemented as software or as a combination of software and hardware, and the bluetooth communication apparatus based on the gateway scheduling connection may be integrated in a certain device in a communication system, such as a bluetooth gateway device. As shown in fig. 3, the method comprises the steps of:
step 301, creating a second service, wherein the second service is used for simulating a second device;
in this step, the bluetooth gateway creates a gatt server locally to simulate the bluetooth devices managed by the bluetooth gateway, and sends the first broadcast signal, since the bluetooth gateway can manage a plurality of bluetooth devices, the broadcast signal may be alternated among broadcast signals of the plurality of bluetooth devices, for example, if the bluetooth gateway manages 5 bluetooth devices altogether, the broadcast signal may be alternated every 0.2 seconds, so that within 1 second, the broadcast signals of the 5 devices may be alternated.
in this step, the bluetooth gateway transmits a first broadcast signal through the second service created in step 310, where the first broadcast signal carries information of the second device, and the information of the second device may be, for example, a MAC address, a device type ID, and the like of the bluetooth device, and since the bluetooth gateway may be connected with a plurality of bluetooth devices, the bluetooth gateway may broadcast the broadcast signal in a time-sharing carousel manner, and broadcast the MAC addresses and/or the device type IDs of the plurality of bluetooth devices in turn.
the first device may be a user device which is always scanning for broadcast signals of the bluetooth gateway and which sends connection information of the first device to the bluetooth gateway when a broadcast signal with information of the second device is scanned. And when the Bluetooth gateway receives the connection information of the first equipment, sending first information to the first equipment. Here, the connection information of the first device may be a user ID and/or a MAC address of the user equipment, and the first information may be a key value, and a typical example of this step is that the bluetooth gateway receives the user ID and/or the MAC address of the user, authenticates the user ID, and if the authentication is passed, sends a key value to the user equipment, where the key value is used for connecting with the user equipment when the user equipment is scheduled later.
Step 304, adding the first device into a scheduling queue, and triggering a scheduling;
and maintaining a scheduling queue in the Bluetooth gateway, wherein the scheduling queue is the user ID of all user equipment requesting Bluetooth connection with the second equipment, and when the user ID passes authentication, adding the user ID into the scheduling queue and triggering one-time scheduling, wherein the scheduling can be based on a scheduling strategy. The scheduling policy may be based on priority, for example, the ue a wants to connect to the bluetooth device C, but the ue B is communicating with the bluetooth device C at this time, when scheduling is triggered, the priorities of the ue a and the ue B are determined, if the priority of the ue a is higher than that of the ue B, the communication between the ue B and the bluetooth device C is directly interrupted, the ue a is scheduled to communicate with the bluetooth device C, if the priorities of the ue a and the ue B are the same, whether the communication between the ue B and the bluetooth device C is idle is determined, and if the communication is idle, the ue a is scheduled to communicate with the bluetooth device C. The scheduling policy described above is merely an example, and is not limited to the above policy in practical use.
if it is determined in the scheduling in step 303 that the first device is scheduled, the gateway connects the first device according to the first information transmitted in step 302. In this step, the bluetooth gateway scans the second broadcast signal of the first terminal, and since the second broadcast signal carries the first information, the bluetooth gateway can determine the first device according to the first information and connect the first device.
In this step, the first device may connect to the second service via a broadcast signal transmitted by the second service, and since the second service emulates the second device, the broadcast signal carries information about the second device, such as the MAC address of the second device, and thus, for the first device, connecting to the second service is equivalent to connecting to the second device.
In this embodiment, the bluetooth communication method based on gateway scheduling connection may further include the following steps:
after step 306, it may further include:
The timer of this step may be implemented in various forms, either as a timer on the bluetooth gateway that decrements with time, or as a timer in the form of a token, which is used by the first device to connect with the second service. The timer includes the remaining active time of the bluetooth connection, which decreases as the time of the connection becomes longer. In one embodiment, the timer may also be implemented in the form of a traffic count, i.e. the amount of data that can be transferred between the first device and the second device is fixed.
After step 307, the method may further include:
In a typical application, if the current scheduling does not schedule the first device but schedules other devices, the bluetooth gateway sends a disconnection instruction to the first device to disconnect the connection between the first device and the second service. For example, the above process is illustrated, where the timer is a token, the bluetooth gateway sends the token to the first device, and specifies that the valid time of the token is 45 seconds, and the scheduling period of the bluetooth gateway is 30 seconds, when scheduling is triggered, it determines that the currently scheduled device is, if the currently scheduled device is still the first device, updates the valid time of the token to 45 seconds, and if the currently scheduled device is not the first device, sends a disconnection instruction to the first device, so that the first device is disconnected from the second service; if the Bluetooth gateway has a problem, so that the Bluetooth gateway disconnection instruction cannot be sent to the first device, when the token holding time of the first device reaches 45 seconds, the Bluetooth connection is also closed, and the first device disconnects the second service.
In this embodiment, the bluetooth communication method based on gateway scheduling connection may further include the following steps:
before step 301, the method may further include:
In step 3001, after the bluetooth device is powered on for the first time or the device is reset, the bluetooth device sends a broadcast signal, and after the bluetooth gateway receives the broadcast signal, the bluetooth device is connected. After connecting to the bluetooth device in step 3002, receiving the type ID information sent by the bluetooth device, and after receiving the type ID information in step 3003, the bluetooth gateway querying the cloud for various attribute information of the bluetooth device, such as the MAC address of the bluetooth device, according to the type ID information of the bluetooth device. The second service created in step 301 may create a second service according to the information of the second device queried in step 3003, so as to simulate the second device through the second service.

The bluetooth gateway then creates a gatt server locally, simulates the bluetooth device sending a broadcast signal, the broadcast signal includes the MAC address of the bluetooth device, and when a user device wants to connect to the bluetooth device, it scans the broadcast signal with the MAC address of the Bluetooth device sent by the Bluetooth gateway, then connects the Bluetooth gateway and sends the user id of the user device, the Bluetooth gateway authenticates the user id, if the authentication is passed, a key value is sent to the user equipment, and after the user equipment receives the key value, a gatt server is created locally and a broadcast signal with the key value is sent, after the bluetooth gateway authenticates the user equipment, a schedule can be triggered, and if the user equipment is determined to be scheduled, connecting the user equipment with the key value, and connecting the user equipment to a gatt server simulating the Bluetooth equipment on the Bluetooth gateway. When other equipment is dispatched, the Bluetooth gateway sends a command to the user equipment to disconnect the user equipment from the gatt server simulating the Bluetooth equipment; or after the Bluetooth connection expires, the user equipment is disconnected from the gatt server simulating the Bluetooth equipment.
