Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

Today, Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which is mainly responsible for the formulation of Bluetooth technical specifications. The Bluetooth technical specification has evolved from the Bluetooth technical specification version 1.0 to the Bluetooth technical specification version 4.2. In version 4.0 of the Bluetooth technical specification, SIG first proposed low-power Bluetooth, that is, Bluetooth technical specification 4.0 includes two technical specifications of traditional Bluetooth and low-power Bluetooth. Traditional Bluetooth can also be called classic Bluetooth. Traditional Bluetooth and Bluetooth Low Energy are two completely different technical specifications. Traditional Bluetooth 4.0 is an upgraded version of traditional Bluetooth 3.0 and is backward compatible. And Bluetooth Low Energy is a new branch and is not backward compatible.

The following is a brief description of the differences between traditional Bluetooth and Bluetooth low energy.

When using Bluetooth Low Energy to transmit data, the length of the data packet is shorter. Bluetooth Low Energy is mainly used in products with high real-time requirements but relatively low data transmission rate. Such as: remote control products (such as: keyboard or remote control mouse) and sensing equipment (such as: heart rate belt, blood pressure monitor, temperature sensor), etc. When using traditional Bluetooth to transmit data, the length of the data packet is relatively long. Traditional Bluetooth is mainly used in products that have relatively high data transmission rates and need to transmit large amounts of data (such as audio data or video data). Such as: mobile phones, tablet computers, media players, robotics systems, handheld devices, notebook computers, gamepads, and some high-quality headphones, modems, watches, etc.

After using Bluetooth Low Energy to complete sending and receiving data, Bluetooth Low Energy will suspend the transmission of wireless signals (but still receive data) and wait for the next connection to be activated again. The traditional Bluetooth is to keep connected.

It takes only 3 milliseconds to complete a Bluetooth low energy wireless connection (scan other devices, establish a link, send data, authenticate and terminate appropriately). It takes hundreds of milliseconds to complete a traditional Bluetooth wireless connection.

Bluetooth low energy has no power level, the general transmission power is +4dBm, and the transmission distance can be 70m. The traditional Bluetooth has 3 power levels, supporting transmission distances of 100 meters, 10 meters, and 1 meter respectively.

In summary, compared to traditional Bluetooth, the advantages of low energy Bluetooth are fast search, fast connection, ultra-low power consumption to maintain the connection and transmit a small amount of data (such as: notification tone (such as incoming call notification tone, ring back tone, SMS) Prompt tone, etc.)), but the data transmission rate of Bluetooth Low Energy is low. Although traditional Bluetooth has a higher data transmission rate, it has a higher power consumption.

Currently, the wireless connection established by the Bluetooth device and the mobile phone may be a traditional Bluetooth connection or a BLE connection. When the traditional Bluetooth connection is used, user services are mainly used to achieve high-speed transmission of large amounts of data (such as audio data or video data). When the BLE connection is used, the standby power consumption is mainly used to realize the low-speed transmission of a small amount of data. With the increase in the amount of user service data, users both hope that Bluetooth devices can reach a higher data transmission rate, but also want to enable Bluetooth devices to have long battery life and standby, but these are two contradictory aspects. Therefore, how to enable Bluetooth devices to achieve high-speed data transmission and low power consumption and long battery life is an urgent problem to be solved.

An embodiment of the present application provides a Bluetooth switching method, which can be applied in the process of transmitting high-speed data between an electronic device (such as a smart phone) and a Bluetooth device (such as a wearable device). Among them, the Bluetooth device may specifically include a BLE device and a traditional Bluetooth device. The BLE device is used to implement the function of Bluetooth Low Energy. The traditional Bluetooth device is used to implement the functions of the traditional Bluetooth. The method includes: the Bluetooth device establishes a first Bluetooth connection with the electronic device, the first Bluetooth connection is a BLE connection, and when the processor of the Bluetooth device determines that the first service is available, controlling the traditional Bluetooth device to power on, the traditional Bluetooth device and the electronic device Establish a second Bluetooth connection, the second Bluetooth connection is a traditional Bluetooth connection, so that the traditional Bluetooth device transmits the data of the first service to the electronic device through the second Bluetooth connection; when the processor of the Bluetooth device determines that the first service transmission is complete, it controls the traditional The Bluetooth device is powered off, the second Bluetooth connection between the traditional Bluetooth device and the electronic device is disconnected, and the first Bluetooth connection between the low-power Bluetooth device and the electronic device is maintained.

In the following, the first service may refer to a service requiring high-speed transmission of large amounts of data. In some embodiments, the first service may be a voice service (such as voice calls or using applications (such as WeChat, Facebook) for voice calls) or video services (such as video playback or using Application (e.g. WeChat, Facebook) for video calls). Correspondingly, the data of the first service may include audio data and video data. Audio data may include: voice data during a call, voice data or voice messages during a voice call or video call using an application (eg, WeChat, Facebook), music, voice data during video playback, and so on. The video data may include: image data during a video call using an application program (eg, WeChat, Facebook), image data during video playback, and so on.

In the Bluetooth switching method provided by the embodiments of the present application, when there is no first service, the Bluetooth device can maintain the first Bluetooth connection with the electronic device through Bluetooth low energy, so as to realize low power consumption standby, and transmit non-first Bluetooth through the first Bluetooth connection. A small amount of business data; when there is the first business, the Bluetooth device can automatically switch to the second Bluetooth connection, and high-speed data transmission can be realized through the second Bluetooth connection. Thus, the Bluetooth device can achieve high-speed data transmission and low power consumption and long battery life, which effectively improves the user experience of the Bluetooth device.

In some embodiments, the Bluetooth device may pre-store service identifiers related to services that require high-speed transmission of large amounts of data. For example, a business identification library can be established, and the business identification library includes at least one business identification. After the Bluetooth device obtains the current service ID, it compares the current service ID with the service ID in the service ID library. If the service ID library covers the current service ID, the Bluetooth device can determine that the service corresponding to the current service ID is not a big data stream. For business, there is no need to use a traditional Bluetooth device to transmit the data of the business corresponding to the current business identifier.

The Bluetooth device may be a wearable device. Wearable devices can also be called wearable smart devices. It is a general term for the application of wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories. Wearable devices are not only a hardware device, but also realize powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include full-featured, large-sized, complete or partial functions that can be achieved without relying on smart phones, such as smart watches or smart glasses, and only focus on a certain type of application function, and need to cooperate with other devices such as smart phones. Use, such as various smart bracelets and smart jewelry for physical sign monitoring.
