In some embodiments, the display device may communicate with a plurality of terminal devices through the bluetooth module to control the terminal devices, wherein the terminal devices are external devices located outside the body of the display device.

In order to implement bluetooth communication between the display device and a plurality of external devices, in some embodiments, two bluetooth modules are disposed on the display device, which are a Mesh bluetooth module and a BLE bluetooth module respectively.

It should be noted that the Mesh network constructed by the display device depends on the bluetooth low energy technology, which is a wireless communication protocol stack used by the blue Mesh controller.

It can be seen that the display device can perform bluetooth communication with multiple external devices simultaneously through two bluetooth modules, however, this communication manner leads to a significant increase in the cost of bluetooth communication. If only one BLE Bluetooth module in the Mesh Bluetooth module is adopted, the Bluetooth transmission bandwidth is limited, and phenomena such as packet loss and jamming may occur in the Bluetooth communication between part of terminal equipment and display equipment, so that the user experience is influenced.

In order to improve the bluetooth communication effect, the embodiment of the application sets two connected bluetooth hosts through the bluetooth module of the display device, one is the Mesh controller, and the other is the BLE controller, receives the bluetooth broadcast packet through the two controllers, can avoid the bluetooth broadcast packet from being omitted by the display device, and only sets one bluetooth main chip to reduce the cost.

Referring to fig. 6, which is a schematic structural diagram of a bluetooth module according to some embodiments, as shown in fig. 6, the bluetooth module may include a bluetooth master chip, a Mesh controller, a BLE controller, a Mesh antenna, and a BLE antenna.

In some embodiments, the bluetooth master chip is a bluetooth host, and the Mesh controller, the BLE controller, the Mesh antenna and the BLE antenna form a bluetooth module.

In some embodiments, the bluetooth master chip is connected to the Mesh controller and the BLE controller of the bluetooth module through the USB hub, respectively. Mesh controller and BLE controller can be provided with two different bluetooth addresses, and the Mesh controller and BLE controller can be distinguished to bluetooth master chip accessible these two bluetooth addresses. The bluetooth address of the BLE controller may be referred to as a USB address 1, and may also be referred to as a first address, and the bluetooth address of the Mesh controller may be referred to as a USB address 2, and may also be referred to as a second address.

In some embodiments, the Mesh controller and the BLE controller may be connected by an SPI (Serial Peripheral Interface) bus. The Mesh controller is electrically connected with the Mesh antenna, and the BLE controller is electrically connected with the BLE antenna.

The connection mode between the bluetooth master chip and the Mesh controller, the connection mode between the bluetooth master chip and the BLE controller, and the connection mode between the Mesh controller and the BLE controller are only exemplary descriptions, and in actual implementation, other connection modes may be adopted. Referring to fig. 7, a data transmission diagram of a bluetooth host according to some embodiments is shown in fig. 7, where the bluetooth host may activate a BLE thread and a Mesh thread respectively through a bluetooth protocol stack. BLE thread accessible BLE drives and communicates with BLE controller that the address is USB address 1, and Mesh thread accessible Mesh drives to communicate with the Mesh controller that the address is USB address 2. The BLE drive and the Mesh drive are both USB drives, and therefore, bluetooth protocol frames are respectively communicated with the Mesh controller and the BLE controller through the two USB drives, HCI (Human-Computer Interaction) data transmitted by the two controllers are processed, and the communication with the Mesh controller and the communication with the BLE controller are not interfered with each other. The HCI data can include some control data, such as switch commands, volume adjusting commands and other data; the Mesh controller outputs Mesh broadcast data to the bluetooth master chip, and the Mesh broadcast data may specifically include the following data: the device comprises a PB-ADV broadcast packet sent by the device when the device is added into the Mesh network, a Mesh Beacon broadcast packet sent by the device before the device is added into the Mesh network, and a data packet Mesh sent by data communication after the device is connected into the network.

The BLE controller outputs to the bluetooth master chip general broadcast data, which may specifically include the following data: name of the broadcasting device, service type of the broadcasting device, factory information of the broadcasting device, and the like.

In some embodiments, the bluetooth module of the display device has two operating states, namely a broadcast state and a scan state, and the bluetooth communication method in these two operating states is described below.

When the display device needs to broadcast the Bluetooth data to other devices, the display device can switch the Bluetooth module into a broadcasting state, and two Bluetooth modules of the Bluetooth module are controlled to work cooperatively. For example, a specific method for the display device to set the bluetooth module to the broadcast state may be: the Bluetooth host sends a broadcast parameter setting instruction to the Bluetooth module, sets data to be broadcast, and finally sends a broadcast starting instruction to start the broadcast state of the Bluetooth module after the broadcast parameters and the broadcast data are set.

In some embodiments, a method for broadcasting bluetooth data by a display device may be as shown in fig. 8, which is a flowchart illustrating a method for broadcasting bluetooth data according to some embodiments, the method being used for a bluetooth master chip of a bluetooth module, and as shown in fig. 8, the method may include the following steps:

step S110: and transmitting the first broadcast parameters to the BLE controller with the first address, and transmitting the second broadcast parameters to the BLE controller with the second address.

In some embodiments, the first broadcast parameter transmitted by the bluetooth master chip comprises a first broadcast interval and the second broadcast parameter comprises a second broadcast interval. The first broadcast parameter may also be referred to as broadcast parameter 1, the second broadcast parameter may also be referred to as broadcast parameter 2, and the first broadcast interval and the second broadcast interval are different, so that collision can be avoided or reduced when the BLE controller and the Mesh controller perform bluetooth broadcast.

For example, the interval time of the broadcast is 20 ms to 10.24 s, and the broadcast interval of the first broadcast parameter may be set to range from 1.28 s to 2.56 s. The second broadcast parameter has a broadcast interval ranging from 2.57 seconds to 5.14 seconds. Before the Bluetooth module is set to be in a broadcast state, determining broadcast parameters, and avoiding conflict between mesh and BLE broadcast as much as possible.

Step S120: sending BLE broadcast data to the BLE controller, and sending Mesh broadcast data to the Mesh controller.

In some embodiments, BLE broadcast data sent by the bluetooth master chip to the BLE controller may be referred to as broadcast data 1, and Mesh broadcast data sent by the bluetooth master chip to the Mesh controller may be referred to as broadcast data 2.

Step S130: controlling the BLE controller and the Mesh controller to initiate broadcasting, wherein the BLE controller and the Mesh controller are both configured to broadcast using the first address, a broadcasting type of the BLE controller is configured to be unconnected, and a broadcasting type of the Mesh controller is configured to be connectable.

In some embodiments, the bluetooth master chip may send a start command of bluetooth broadcast to the BLE controller and the Mesh controller, respectively, and the BLE controller and the Mesh controller may broadcast according to the respective received bluetooth broadcast parameters and bluetooth data after receiving the start command.

In some embodiments, the BLE controller and the Mesh controller both broadcast using the first address of the BLE controller, so that the display device is externally a bluetooth address, which facilitates bluetooth communication between the external device and the display device. The external device is a device which is located outside the display device and performs bluetooth communication with the display device, such as a bluetooth sound box and a bluetooth handle.

When Mesh controller received bluetooth master chip start broadcasting order, the Mesh controller obtained the bluetooth address in the BLE controller through SPI, carried out the comparison with Mesh controller's address itself, if different, then used the bluetooth address of BLE controller to broadcast to realize that BLE controller and Mesh controller all use the first address of BLE controller to broadcast.

In some embodiments, the BLE controller and the Mesh controller may also both broadcast using the second address of the Mesh controller.

There is no difference in using the first address and the second address for broadcasting.

In some embodiments, the broadcast type of the BLE controller is configured to be connectible and the broadcast type of the Mesh controller is configured to be non-connectible.

Among the connectable broadcast type PDU types of the BLE controller, ADV _ IND (non-directional broadcast type) and ADV _ DIRECT _ IND (directional broadcast type) are mainly used. When the scanning device detects the connectable broadcast type, the scanning device judges the connectable broadcast type to be BLE broadcast. The PDU Type of the connectionless broadcast Type of the Mesh controller is ADV _ non _ IND (connectionless non-oriented broadcast Type), and a broadcast packet of the Type is used only for broadcast data, is not connectible, and is available for broadcast of the Mesh.

To further illustrate the method of the display device initiating a bluetooth broadcast, fig. 9 illustrates a timing diagram of a bluetooth broadcast initiation method according to some embodiments.

As shown in fig. 9, the bluetooth master chip sends the first broadcast parameter and BLE broadcast data to the BLE controller through a BLE thread, and controls the BLE controller to start broadcasting, where the broadcasting type is general, and the broadcasting type is equivalent to the broadcasting type being connectable.

As shown in fig. 9, the bluetooth master chip sends the second broadcast parameter and the Mesh broadcast data to the Mesh controller through the Mesh thread, and controls the BLE controller to start broadcasting, where the broadcasting type is not connectable.

In some embodiments, the Mesh thread further acquires a BLE broadcasting interval from the BLE thread, so that the broadcasting interval of the Mesh controller is adjusted according to the BLE broadcasting interval, and collision occurring when the BLE controller and the Mesh controller perform bluetooth broadcasting is reduced or avoided.

The above-described embodiment describes the bluetooth broadcast startup method after the display device is switched to the broadcast state. When the display equipment needs to acquire the data of other equipment, the display equipment can switch the Bluetooth module into a scanning state, and two Bluetooth modules of the Bluetooth module are controlled to work cooperatively.

In some embodiments, the process of performing bluetooth scanning by the display device may be divided into two major steps, where the bluetooth master chip sets the BLE controller and the Mesh controller to be in a scanning state, and the BLE controller and the Mesh controller process the bluetooth broadcast packet when the bluetooth broadcast packet is scanned.

In some embodiments, the process of setting the BLE controller and the Mesh controller to the scan state by the bluetooth master chip is similar to the step of setting the BLE controller and the Mesh controller to the broadcast state, and the BLE controller and the Mesh controller are respectively set to the scan state by different USB addresses.

Illustratively, the specific setting method for setting to the scan state is as follows: firstly, setting scanning parameters, wherein the parameters comprise scanning time and a scanning window; then a scan is initiated.

In some embodiments, the Mesh controller is configured to start scanning for bluetooth broadcast packets after the scan state. If the Bluetooth broadcast packet is scanned, whether the Bluetooth broadcast packet is a BLE broadcast packet or a Mesh broadcast packet can be analyzed, if the Bluetooth broadcast packet is the Mesh broadcast packet, the Mesh broadcast packet is processed by the Bluetooth broadcast packet, and if the Bluetooth broadcast packet is the BLE broadcast packet, the BLE broadcast packet is sent to a BLE controller to be processed.

In some embodiments, the BLE controller is configured to start scanning for bluetooth broadcast packets after the scan state. If the Bluetooth broadcast packet is scanned, whether the Bluetooth broadcast packet is a BLE broadcast packet or a Mesh broadcast packet can be analyzed, if the Bluetooth broadcast packet is the BLE broadcast packet, the BLE broadcast packet is processed by the Bluetooth broadcast packet, and if the Bluetooth broadcast packet is the Mesh broadcast packet, the Mesh broadcast packet is sent to a Mesh controller to be processed.

In some embodiments, referring to fig. 10, a process of processing bluetooth data transmitted by an external device by a bluetooth module is a flowchart of a bluetooth data processing method according to some embodiments, as shown in fig. 10, the method may include the following steps:

step S210: in one Bluetooth module, bluetooth broadcast packets are scanned simultaneously through a Mesh controller and a BLE controller, wherein the Mesh controller and the BLE controller are connected.

In some embodiments, after the bluetooth master chip sends the scan command to the Mesh controller and the BLE controller, respectively, the Mesh controller and the BLE controller simultaneously scan the bluetooth broadcast packet according to the scan command, respectively. It should be noted that the term "simultaneously" refers to a moment when both the Mesh controller and the BLE controller scan the bluetooth broadcast packet, rather than starting scanning and ending scanning at the same time strictly, and in fact, the time for starting and ending scanning the bluetooth broadcast packet may be different between the Mesh controller and the BLE controller.

Step S220: and if the Bluetooth broadcast packet scanned by the Mesh controller is a BLE broadcast packet, sending the BLE broadcast packet to the BLE controller for processing.

In some embodiments, since the Mesh controller and the BLE controller are connected by an SPI bus, if the bluetooth broadcast packet scanned by the Mesh controller is a BLE broadcast packet, the Mesh controller may send the BLE broadcast packet to the BLE controller through the SPI bus for processing.

Step S230: and if the Bluetooth broadcast packet scanned by the BLE controller is a Mesh broadcast packet, sending the Mesh broadcast packet to the Mesh controller for processing.

In some embodiments, because the Mesh controller and the BLE controller are connected by an SPI bus, if the bluetooth broadcast packet scanned by the BLE controller is a Mesh broadcast packet, the BLE controller may send the Mesh broadcast packet to the Mesh controller through the SPI bus for processing.

Of course, if the bluetooth broadcast packet scanned by the Mesh controller is a Mesh broadcast packet, the Mesh controller processes the Mesh broadcast packet; and if the Bluetooth broadcast packet scanned by the Mesh controller is a Mesh broadcast packet, processing the Mesh broadcast packet by the Mesh controller.

For further description of the method illustrated in fig. 10. Figure 11 illustrates a flow diagram of a bluetooth data processing method for a Mesh controller, according to some embodiments. As shown in fig. 11, the method may include the steps of:

step S310: the Mesh controller starts scanning the bluetooth broadcast packet.

Step S320: and judging whether the broadcast packet is not connectable according to the PDU _ Type of the Bluetooth broadcast packet.

In some embodiments, the bluetooth broadcast packet is modem and PDU _ Type and AD Type are obtained.

In some embodiments, the PDU _ Type represents a PDU Type, and there are two types, one is connectable and one is not connectable, if PDU _ Type is connectable, the bluetooth broadcast packet is connectable, and if PDU _ Type is not connectable, the bluetooth broadcast packet is not connectable.

In some embodiments, the AD Type indicates a broadcast packet Type, and there are two types, one is Mesh and one is BLE. If the AD Type is Mesh, it indicates that the bluetooth broadcast packet is Mesh broadcast packet, if the AD Type is BLE, it indicates that the bluetooth broadcast packet is BLE broadcast packet.

Step S330: if the broadcast packet is not connectable, the AD Type of the broadcast packet is checked, and whether the AD Type is Mesh is judged.

In some embodiments, both the Mesh broadcast packet and the BLE broadcast packet may be connectionless broadcast packets, only the BLE broadcast packet may be connectionless packets, and the Mesh broadcast packet may not be connectionless packets. Therefore, if the received bluetooth broadcast packet is an unconnected broadcast packet, further determination is required.

Step S340: if the AD Type is Mesh, the AD Type is judged to be a Mesh broadcast packet, and the Mesh controller processes the Bluetooth broadcast packet.

In some embodiments, if the AD Type is Mesh, the Mesh controller determines that the bluetooth broadcast packet is a Mesh broadcast packet, and may process the bluetooth broadcast packet.

In some embodiments, an example of the Mesh controller processing the bluetooth broadcast packet is: the Mesh controller removes the leading frame, the access address and the LL frame field of the broadcast packet, organizes the remaining data into an HCI event format and reports the HCI event format to the Bluetooth host.

Step S350: if the AD Type is not Mesh, the Bluetooth broadcast packet is judged to be a BLE broadcast packet, and the BLE controller processes the Bluetooth broadcast packet.

In some embodiments, if the AD Type is not Mesh, the Mesh controller determines that the bluetooth broadcast packet is a BLE broadcast packet, and may transmit the bluetooth broadcast packet to the BLE controller.

Step S360: if PDU _ Type is the joinable broadcast packet, judge that it is BLE broadcast packet, transmit it through the SPI bus to BLE controller.

In some embodiments, if PDU _ Type is an connectible broadcast packet, the Mesh controller determines that the bluetooth broadcast packet is a BLE broadcast packet, and may transmit the bluetooth broadcast packet to the BLE controller.

Step S370: the BLE controller processes the Bluetooth broadcast packet.

In some embodiments, the BLE controller may process the bluetooth broadcast packet sent by the Mesh controller after receiving the broadcast packet.

In some embodiments, one example of the processing of the bluetooth broadcast packet by the BLE controller is: and judging whether the type of the broadcast packet can be connected or not, if not, directly removing the leading frame of the broadcast packet, and reporting the LL header to the Bluetooth host. If connectable, the BLE controller negotiates with the broadcasting device a physical path and connection interval for the next connection. Ready for connection.

Step S380: and sending the processed data to the Bluetooth main chip.

In some embodiments, the Mesh controller or BLE controller may send the processed data to the bluetooth master chip.

In some embodiments, the bluetooth data processing method for BLE control is similar to that in fig. 11, and only the Mesh controller and BLE controller in fig. 11 need to be replaced with each other.

The method illustrated in fig. 11 is only an exemplary description, and in some embodiments, other methods may be used to determine the Mesh broadcast packet and the BLE broadcast packet. For example, the bluetooth broadcast packet is directly judged to be the Mesh broadcast packet or the BLE broadcast packet according to the AD Type, and the PDU _ Type is no longer judged.

According to the above method for bluetooth communication provided by the embodiment of the present application, an example of bluetooth communication between one display device and a plurality of external devices is as follows:

in a user family scene, the external device performing bluetooth communication with the television comprises a plurality of bluetooth switches, a plurality of bluetooth handles and bluetooth earphones supporting BLE Audio, wherein the number of the bluetooth switches is 1, the number of the bluetooth switches is respectively used for controlling the illumination of a plurality of lamps in the user family, the number of the bluetooth earphones is used for playing Audio sent by the television and receiving voice input by the user, and the number of the bluetooth handles is 1, the bluetooth handles are used for inputting control instructions, such as some game instructions, to the television.

BLE Mesh networking is carried out through display device's Mesh controller between TV and the bluetooth switch, and the Bluetooth communication is carried out through display device's BLE controller between TV and the game paddle, can not carry out the bluetooth and be connected between TV and the bluetooth headset, but carries out data transceiver with the mode of broadcasting.

The user opens a game on the television, which communicates with the bluetooth handle as follows:

1) The broadcast is started to the bluetooth handle, and TV control BLE controller launches the scanning, scans the bluetooth handle after, connects, acquires the button information that user operation bluetooth handle produced.

2) After the Bluetooth handle is connected with the television, the key information of the Bluetooth handle is sent to the television in the form of a Bluetooth data packet, and the television processes the key information to perform corresponding game reaction.

If the television receives the control information of the Bluetooth switch, the control information can be processed by the Mesh controller.

If the user inputs voice while operating the Bluetooth handle, so as to perform voice interaction with game friends, when the television receives the Bluetooth data packet of the Bluetooth handle, the television also needs to receive the Bluetooth broadcast packet containing the voice of the user, which is sent by the Bluetooth headset, and the Bluetooth data packet containing the voice of the user and the Bluetooth data packet of the Bluetooth handle need to be processed by the BLE controller, so that the problem that the BLE controller cannot receive all the Bluetooth broadcast packets containing the voice may occur.

As can be seen from the above embodiments, in the embodiments of the present application, a Mesh controller and a BLE controller connected to each other are arranged in a bluetooth module, and the Mesh controller and the BLE controller are configured to scan bluetooth broadcast packets at the same time, and since the Mesh antenna and the BLE antenna scan BLE common broadcast packets together and modulate the BLE common broadcast packets, when the BLE antenna is in full load and some BLE broadcast packets are not scanned, the Mesh antenna is still idle, and the Mesh antenna can modulate and demodulate broadcast packets that are not scanned by the BLE antenna, and transmit the broadcast packets to the BLE controller after the processing. Through the method, the BLE controller can still receive the BLE broadcast packet which is not scanned by the BLE controller through the SPI bus under the condition of insufficient physical bandwidth, so that the bandwidth and the processing capacity are increased, the problem of loss of the Bluetooth broadcast packet is reduced and even avoided, and the Bluetooth communication quality is improved; moreover, only one Bluetooth module is needed for Bluetooth communication, so that the cost of the Bluetooth communication is effectively controlled.

Since the above embodiments are all described by referring to and combining with other embodiments, the same portions are provided between different embodiments, and the same and similar portions between the various embodiments in this specification may be referred to each other. And will not be described in detail herein.
