Fig. 1 is a schematic architecture diagram of a system 10 according to an embodiment of the present disclosure.
Referring to fig. 1, the system 10 in the embodiment of the present application includes a first bluetooth device 101 and a second bluetooth device 102. The first bluetooth device 101 and the second bluetooth device 102 may be connected directly through Bluetooth Low Energy (BLE) technology or WiFi.
The first bluetooth device 101 may be an intelligent terminal device such as a smart television that includes a bluetooth function and a network function. The second bluetooth device 102 may be a bluetooth-enabled mobile device, such as an electronic device like a bluetooth remote controller, a bluetooth headset, etc. The bluetooth remote controller is not limited to the bluetooth remote controller matched with the first bluetooth device 101, and may also be a mobile phone or tablet or other terminal device with a bluetooth function and equipped with a remote controller application.
Based on the system architecture in fig. 1, fig. 2 is a schematic diagram illustrating an embodiment of a data processing method according to an embodiment of the present application. Referring to fig. 2, an embodiment of the data processing method provided in the embodiment of the present application may specifically include the contents of step 210 to step 220.
210. The first Bluetooth device acquires an upgrade file of the second Bluetooth device.
In the embodiment of the application, when detecting that the second bluetooth device meets the upgrade condition, the first bluetooth device acquires the upgrade file matched with the second bluetooth device.
Optionally, in this embodiment of the application, when detecting that an upgrade file matched with the second bluetooth device is locally stored, or when receiving an upgrade waiting instruction corresponding to the second bluetooth device, the first bluetooth device may determine that the second bluetooth device meets an upgrade condition. The instruction for waiting for upgrade may be sent by the second bluetooth device, or may be sent by the server.
Optionally, in this embodiment of the present application, when it is detected that the second bluetooth device meets the upgrade condition, if the first bluetooth device locally stores the upgrade file matched with the second bluetooth device, the upgrade file is directly acquired from the local storage. If the first Bluetooth device does not locally store the upgrade file matched with the second Bluetooth device, the first Bluetooth device may send an upgrade instruction to the server, so that the server sends the upgrade file matched with the second Bluetooth device to the first Bluetooth device according to the upgrade instruction.
220. And the first Bluetooth equipment sends the upgrade file to the second Bluetooth equipment according to the transmission configuration information so that the second Bluetooth equipment can upgrade according to the upgrade file.
In this embodiment of the present application, the transmission configuration information refers to data transmission parameters and specific values in a data transmission process between the first bluetooth device and the second bluetooth device. It should be noted that, in this embodiment of the application, the data transmission parameter that the first bluetooth device and the second bluetooth device need to negotiate to determine includes at least one of a Maximum Transmission Unit (MTU) and a data transmission interval (connection interval min) of a network protocol. The maximum transmission unit is the maximum length of a single data packet in the data transmission process of the first Bluetooth device and the second Bluetooth device; the data transmission interval is the interval of the transmission time corresponding to each adjacent data packet in the data transmission process of the first Bluetooth device and the second Bluetooth device. The data transmission parameters and the specific values are determined by the first Bluetooth device and the second Bluetooth device through negotiation in advance. In this embodiment of the application, when the data transmission parameter negotiated in advance by the first bluetooth device and the second bluetooth device includes a maximum transmission unit, a value of the maximum transmission unit determined by negotiation in advance is a target maximum transmission unit. In this embodiment, the target maximum transfer unit negotiated and determined by the first bluetooth device and the second bluetooth device is greater than the default standard maximum transfer unit in the GATT protocol. In this embodiment of the application, when the data transmission parameter negotiated and determined in advance by the first bluetooth device and the second bluetooth device includes a data transmission interval, a value of the negotiated and determined data transmission interval is a target data transmission interval. Wherein the target data transmission interval is smaller than a default standard transmission interval in the GATT protocol. Optionally, in this embodiment of the present application, the transmission configuration information may be determined by negotiation between the first bluetooth device and the second bluetooth device when the first bluetooth device and the second bluetooth device establish a communication connection for the first time.
It should be noted that, in this embodiment of the present application, the data transmission parameter that the first bluetooth device and the second bluetooth device need to negotiate and determine includes at least one of a maximum transmission unit of a network protocol and a data transmission interval, and may further include other data transmission parameters, for example, a data response method, and the like, which is not limited in this embodiment of the present application. In this embodiment of the application, the first bluetooth device and the second bluetooth device determine a specific value of the data transmission parameter through negotiation, so that a transmission rate after negotiation between the first bluetooth device and the second bluetooth device can be greater than a default transmission rate in a GATT protocol.
In this embodiment of the application, the first bluetooth device and the second bluetooth device negotiate in advance about transmission configuration information in a data transmission process, that is, a specific value of a data transmission parameter, and after the first bluetooth device acquires an upgrade file of the second bluetooth, the upgrade file is sent to the second bluetooth device according to the transmission configuration information negotiated in advance.
Specifically, when the transmission configuration information negotiated in advance by the first bluetooth device and the second bluetooth device includes a target maximum transmission unit, the first bluetooth device splits the upgrade file into a plurality of data packets according to the negotiated target maximum transmission unit, and respectively sends the data packets to the second bluetooth device, wherein the size of each data packet is equal to or smaller than the target maximum transmission unit; when the transmission configuration information negotiated in advance by the first Bluetooth device and the second Bluetooth device comprises a target data transmission interval, the first Bluetooth device sequentially sends a plurality of data packets split by the upgrade file to the second Bluetooth device respectively according to the negotiated target data transmission interval.
In the embodiment of the application, the transmission configuration information in the data transmission process negotiated in advance by the first bluetooth device and the second bluetooth device, that is, the specific value of the data transmission parameter, includes the target maximum transmission unit or the target data transmission interval, so that the transmission rate corresponding to the negotiated transmission configuration information is greater than the default transmission rate of the GATT protocol, when the second bluetooth device needs to be upgraded, the first bluetooth device sends the upgrade file to the second bluetooth device through the transmission configuration information determined by the negotiation in advance with the second bluetooth device, instead of directly sending the upgrade file to the second bluetooth device according to the default data transmission interval or the maximum transmission unit in the GATT protocol, thereby improving the data transmission rate, reducing the transmission time of the upgrade file, and further improving the upgrade efficiency.
Fig. 3 is a schematic diagram of an embodiment of another data processing method according to an embodiment of the present application. Referring to fig. 3, another embodiment of the data processing method provided in the embodiment of the present application may specifically include the contents of step 301 to step 310.
As shown in fig. 3, the method provided in the embodiment of the present application may further include:
301. the first bluetooth device modifies the standard data transmission interval to a first data transmission interval.
In this embodiment, in the GATT connection parameter of the first bluetooth device, the original default data transmission interval is a standard data transmission interval, and the standard data transmission interval is an interval of transmission time corresponding to each adjacent data packet in a transmission process that is default in the GATT protocol. In the embodiment of the application, when the first bluetooth device establishes communication connection with the second bluetooth device for the first time, the default standard data transmission interval is modified to the first data transmission interval. The first bluetooth device may call the HCI _ LE _ Connection _ Update interface to modify the standard data transmission interval to obtain the first time interval. The first data transmission interval is smaller than a standard data transmission interval of the GATT protocol. For example, the first time interval may be 7.5 ms. It should be noted that, the specific value of the first time interval is preset in practical situations, and the embodiment of the present application does not limit this.
302. The first Bluetooth device receives a connection parameter updating request sent by the second Bluetooth device, wherein the connection parameter updating request comprises a data transmission interval of the second Bluetooth device.
In this embodiment of the present application, after the first bluetooth device modifies the standard data transmission interval to the first data transmission interval, a connection parameter update request sent by the second bluetooth device is also received. The first bluetooth device may obtain a value of a data transmission interval of the second bluetooth device as a second data transmission interval according to the connection parameter update request sent by the second bluetooth device. The second data transmission interval is an interval of transmission time corresponding to each adjacent data packet supported by the data transmission process of the second bluetooth device.
303. The first bluetooth device determines whether the second data transmission interval is less than or equal to the first data transmission interval. If yes, go to step 304; if not, go to step 305.
304. And if the second data transmission interval is smaller than or equal to the first data transmission interval, the first Bluetooth device determines that the first data transmission interval is a target data transmission interval.
In this embodiment of the application, if the second data transmission interval is less than or equal to the first data transmission interval, it indicates that the second bluetooth device supports the transmission time interval corresponding to each adjacent data packet to be the first data transmission interval, and at this time, the first bluetooth device may use the first data transmission interval as a target data transmission interval, that is, the first bluetooth device may send the upgrade file to the second bluetooth device according to the target data transmission interval.
305. And if the second data transmission interval is larger than the first data transmission interval, the first Bluetooth device modifies the first data transmission interval into a standard data transmission interval.
In this embodiment of the present application, if the second data transmission interval is greater than the first data transmission interval, it indicates that the second bluetooth device does not support the transmission time interval corresponding to each adjacent data packet as the first data transmission interval, at this time, the first bluetooth device modifies the first data transmission interval into the standard data transmission interval again, and the first bluetooth device sends the upgrade file to the second bluetooth device according to the standard data transmission interval.
306. The first Bluetooth device acquires a second maximum transmission unit of the second Bluetooth device.
In this embodiment of the present application, an originally default maximum transmission unit of the first bluetooth device is taken as a default standard maximum transmission unit in the GATT protocol, and in this embodiment of the present application, the first bluetooth device first modifies the default standard maximum transmission unit into a first maximum transmission unit, where the first maximum transmission unit is greater than the standard maximum transmission unit.
After the above step 304 or step 305, the first bluetooth device obtains the second maximum transmission unit of the second bluetooth device, where the second maximum transmission unit is the maximum length of the data packet that can be transmitted by the second bluetooth device.
Optionally, in this embodiment of the application, the first bluetooth device and the second bluetooth device may send a first instruction for indicating the first maximum transmission unit to the second bluetooth device, and after receiving the first instruction, the second bluetooth device feeds back a second instruction for indicating the second maximum transmission unit to the first bluetooth device. And the first Bluetooth device determines a second maximum transmission unit supported by the second Bluetooth device according to the second instruction. The first bluetooth device may call the ATT _ EXCHANGE _ MTU _ REQ interface, send the first instruction to the second bluetooth device, and receive the second instruction fed back by the second bluetooth device.
Optionally, in this embodiment of the application, the connection parameter update request in step 302 may include the second data transmission interval and the second maximum transmission unit of the second bluetooth device at the same time, and the first bluetooth device may determine the second data transmission interval and the second maximum transmission unit of the second bluetooth device at the same time according to the connection parameter update request.
Optionally, in this embodiment of the application, the first bluetooth device may determine the second maximum transmission unit before or after determining the second data transmission interval, and the specific execution sequence is preset according to an actual situation, which is not limited in this embodiment of the application.
307. The first Bluetooth device determines the minimum maximum transmission unit as the target maximum transmission unit from the first maximum transmission unit and the second maximum transmission unit.
In this embodiment of the present application, after acquiring a second maximum transmission unit of a second bluetooth device, a first bluetooth device determines a minimum value in the first maximum transmission unit and the second maximum transmission unit, and determines the minimum value in the first maximum transmission unit and the second maximum transmission unit as a target maximum transmission unit.
308. The first Bluetooth device sets the data transmission mode to an unacknowledged transmission mode.
The default data transmission mode in the existing GATT protocol is an acknowledgement transmission mode, that is, after a first bluetooth device transmits a data packet to a second bluetooth device, the first bluetooth device needs to wait for the second bluetooth device to feed back an acknowledgement message. In this embodiment of the present application, the first bluetooth device sets the data transmission mode to the non-acknowledgement transmission mode, that is, after the first bluetooth device transmits one data packet to the second bluetooth device, the next data packet can be sent without waiting for the second bluetooth device to feed back the acknowledgement information. Specifically, the first bluetooth device may modify a default data transmission mode (i.e., an acknowledgement transmission mode) in the GATT protocol to a no-acknowledgement transmission mode (write without response), and send configuration information indicating the no-acknowledgement transmission mode to the second bluetooth device, so that the second bluetooth device transmits data with the first bluetooth device in the no-acknowledgement transmission mode.
It should be noted that, in the embodiment of the present application, step 308 may be executed simultaneously with or before or after execution of any one of steps 301 to 307, and the execution time of step 308 is not limited in the embodiment of the present application.
309. The first Bluetooth device acquires an upgrade file of the second Bluetooth device.
The embodiment of the present application can be understood with reference to step 210 in fig. 2, and is not described herein again.
310. And the first Bluetooth equipment sends the upgrade file to the second Bluetooth equipment according to the transmission configuration information so that the second Bluetooth equipment can upgrade according to the upgrade file.
In this embodiment of the application, the first bluetooth device and the second bluetooth device negotiate in advance about transmission configuration information in a data transmission process, that is, a specific value of a data transmission parameter, and after the first bluetooth device acquires an upgrade file of the second bluetooth, the upgrade file is sent to the second bluetooth device according to the transmission configuration information negotiated in advance.
Specifically, the first bluetooth device first splits the upgrade file into a plurality of upgrade data packets according to the negotiated target maximum transmission unit, where the size of each data packet is equal to the target maximum transmission unit. And then, the first Bluetooth device sequentially sends the plurality of data packets split by the upgrade file to the second Bluetooth device according to the negotiated target data transmission interval. For example, the target data transmission interval is 7.5ms, and the first bluetooth device sends an upgrade data packet to the second bluetooth device every 7.5 ms. And the first Bluetooth equipment can send the next upgrading data packet to the second Bluetooth equipment without waiting for the response information fed back by the second Bluetooth equipment when sending one upgrading data packet to the second Bluetooth equipment.
In the embodiment of the application, the first Bluetooth device and the second Bluetooth device negotiate in advance about the transmission configuration information in the data transmission process, i.e. the specific values of the data transmission parameters, the transmission configuration information comprises the target maximum transmission unit, the target data transmission interval, the transmission rate corresponding to the negotiated transmission configuration information is larger than the default transmission rate of the GATT protocol, and a non-response data transmission mode is adopted, when the second Bluetooth device needs to be upgraded, the first Bluetooth device sends the upgrade file to the second Bluetooth device through the transmission configuration information determined by the pre-negotiation with the second Bluetooth device, rather than directly transmitting the upgrade file to the second bluetooth device according to the default data transmission interval and maximum transmission unit in the GATT protocol, therefore, the data transmission rate is improved, the transmission time of the upgrade file is reduced, and the upgrade efficiency is improved.
In the prior art, when the smart television sends the upgrade file to the bluetooth remote controller, the smart television may also receive requests of other bluetooth devices (such as bluetooth headsets, etc.), which results in a high bluetooth bandwidth occupancy rate of the smart television, a slow response speed of the smart television to the bluetooth remote controller, an obvious bluetooth remote controller jam, and a poor user experience. Therefore, in order to solve the above problem, the embodiment of the present application is based on the embodiments in fig. 2 and fig. 3, and further provides another embodiment of a data processing method, please refer to fig. 4.
Fig. 4 is a schematic diagram of an embodiment of another data processing method provided in the embodiment of the present application.

420. And the first Bluetooth equipment sends the upgrade file to the second Bluetooth equipment according to the transmission configuration information so that the second Bluetooth equipment can upgrade according to the upgrade file.
The embodiment of the present application can be understood with reference to step 220 in fig. 2 or step 310 in fig. 3, and is not described herein again.
430. And when detecting that all the upgrading data packets corresponding to the upgrading files are completely sent, the first Bluetooth device sets a white list according to the second Bluetooth device, and configures the security module according to the white list.
In this embodiment of the application, the first bluetooth device may determine whether all the data packets corresponding to the upgrade file are completely sent by detecting whether the lengths of all the upgrade data packets sent are equal to the length of the upgrade file, or detecting whether the number of the upgrade data packets sent is equal to the number of all the upgrade data packets after the upgrade file is split. And when all the upgrading data packets corresponding to the upgrading files are completely sent, the first Bluetooth device sets a white list according to the second Bluetooth device. Optionally, the white list may include identification information of the second bluetooth device, as well as other data associated with the second bluetooth device.
In the embodiment of the application, when it is detected that all upgrade data packets corresponding to the upgrade file are completely sent, the first bluetooth device exits the data packet sending process except for setting a white list according to the second bluetooth device, and sends the upgrade starting instruction to the second bluetooth device, after receiving the upgrade starting instruction, the second bluetooth device firstly checks whether all the upgrade data packets are successfully received, and if all the upgrade data packets are successfully received, the second bluetooth device starts the upgrade process.
440. And after receiving the target data sent by the third Bluetooth device, the first Bluetooth device judges whether the third Bluetooth device belongs to the white list or not through the safety module.
In the embodiment of the application, after the first bluetooth device sets a white list according to the second bluetooth device and configures the security module according to the white list, if target data sent by a third bluetooth device is received, the security module judges whether the third bluetooth device belongs to the white list according to the target data.
450. And when the third Bluetooth equipment does not belong to the white list, the Bluetooth module of the first Bluetooth equipment stores the target data into a preset storage queue through a protocol stack.
In this embodiment of the application, when the security module determines that the third bluetooth device does not belong to the white list, the protocol stack stores the target data into a preset storage queue, and the target data is shielded first, so that the target data is not lost, rather than being reported to the CPU of the first bluetooth device.
460. And when the first Bluetooth equipment receives the upgrading completion instruction sent by the second Bluetooth equipment, the white list is removed.
In the embodiment of the application, when the second bluetooth device finishes upgrading according to the upgrading file, the second bluetooth device sends an upgrading finishing instruction to the first bluetooth device. And when the first Bluetooth equipment receives the upgrading completion instruction sent by the second Bluetooth equipment, the upgrading completion instruction is sent to the safety module, so that the safety module can remove the white list under the upgrading completion instruction.
