Detailed Description

in the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

Today, Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which is mainly responsible for the formulation of the Bluetooth specification. The bluetooth specification has evolved from bluetooth specification version 1.0 to bluetooth specification version 4.2. In the bluetooth specification version 4.0, bluetooth low energy was first proposed by SIG, i.e. bluetooth specification 4.0 includes both the legacy bluetooth and bluetooth low energy specifications. Conventional bluetooth may also be referred to as classic bluetooth. Conventional bluetooth and bluetooth low energy are two completely different specifications. Legacy bluetooth 4.0 is an upgraded version of legacy bluetooth 3.0, being backwards compatible. And bluetooth low energy is a new branch and is not downward compatible.

The following is a brief description of the differences between conventional bluetooth and bluetooth low energy.

When the low-power Bluetooth is used for transmitting data, the length of the data packet is short. Bluetooth low energy is mainly used in products with high real-time requirements but relatively low data transmission rates. Such as: remote control products (such as a keyboard or a remote control mouse), sensing equipment (such as a heart rate belt, a sphygmomanometer and a temperature sensor) and the like. When the traditional Bluetooth is used for transmitting data, the length of the data packet is longer. The conventional bluetooth is mainly applied to products which have relatively high data transmission rate and need to transmit a large amount of data (such as audio data or video data). Such as: mobile phones, tablets, media players, robotic systems, handheld devices, laptops, game pads, and some high-quality headphones, modems, watches, and the like.

After completing the data transmission and reception using bluetooth low energy, bluetooth low energy may suspend transmitting wireless signals (but may still receive data) waiting for the next connection reactivation. Whereas conventional bluetooth is continuously maintaining a connection.

It takes only 3 milliseconds to complete a bluetooth low energy wireless connection (scan for other devices, establish a link, send data, authenticate, and end appropriately). Whereas it takes hundreds of milliseconds to complete a conventional bluetooth wireless connection.

Bluetooth low energy is of no power class, typically with a transmit power of +4dBm, and a transmission distance of 70 m. And the traditional Bluetooth has 3 power levels, and supports transmission distances of 100 meters, 10 meters and 1 meter respectively.

In summary, compared with the conventional bluetooth, the bluetooth low energy has the advantages of fast search, fast connection, ultra-low energy connection and transmission of a small amount of data (e.g., alert tones (such as incoming call alert tone, ring back tone, short message alert tone, etc.)), but the data transmission rate of the bluetooth low energy is low. While the data transmission rate of the conventional bluetooth is high, the power consumption of the conventional bluetooth is large.

Currently, the wireless connection established between the bluetooth device and the mobile phone may be a conventional bluetooth connection or a BLE connection. When the traditional Bluetooth connection is adopted, user services are mainly used, and high-speed transmission of a large amount of data (such as audio data or video data) is realized. When BLE connection is adopted, standby power consumption is mainly used, and low-speed transmission of small data is achieved. As the amount of user traffic increases, users desire both higher data transmission rates and long-endurance standby for bluetooth devices, which are two contradictory aspects. Therefore, how to enable the bluetooth device to realize high-speed data transmission and low-power-consumption long endurance is an urgent problem to be solved.

an embodiment of the present application provides a bluetooth switching method, which may be applied to a process in which an electronic device (e.g., a smart phone) and a bluetooth device (e.g., a wearable device) transmit high-speed data. The bluetooth device may specifically include a BLE device and a legacy bluetooth device. The BLE device is used for realizing the function of the low-power Bluetooth. The conventional bluetooth device is used to implement the functions of the conventional bluetooth. The method comprises the following steps: the method comprises the steps that a first Bluetooth connection is established between a Bluetooth device and an electronic device, the first Bluetooth connection is BLE connection, when a processor of the Bluetooth device determines that a first service exists, a traditional Bluetooth device is controlled to be powered on, a second Bluetooth connection is established between the traditional Bluetooth device and the electronic device, the second Bluetooth connection is traditional Bluetooth connection, and the traditional Bluetooth device and the electronic device transmit data of the first service through the second Bluetooth connection; and after the processor of the Bluetooth device determines that the first service transmission is finished, controlling the traditional Bluetooth device to be powered off, disconnecting the traditional Bluetooth device from the second Bluetooth of the electronic device, and keeping the low-power Bluetooth device connected with the first Bluetooth of the electronic device.

Hereinafter, the first service may refer to a service that requires high-speed transmission of a large amount of data. In some embodiments, the first service may be a voice service (e.g., a voice call or a voice call using an application (e.g., WeChat, Facebook)) or a video service (e.g., a video playback or a video call using an application (e.g., WeChat, Facebook)). Accordingly, the data of the first service may include audio data and video data. The audio data may include: voice data during a call, voice data or voice messages during a voice call or a video call using an application (e.g., WeChat, facebook), music, voice data while playing video, and so on. The video data may include: image data during a video call, image data during a video play, and the like are performed using an application (e.g., WeChat, face book).

According to the Bluetooth switching method provided by the embodiment of the application, when the first service does not exist, the Bluetooth device can keep the first Bluetooth connection with the electronic device through the low-power Bluetooth, so that low-power standby is realized, and a small amount of data which is not the first service is transmitted through the first Bluetooth connection; when the first service exists, the Bluetooth device can be automatically switched to the second Bluetooth connection, and high-speed data transmission can be realized through the second Bluetooth connection. Therefore, the Bluetooth device can realize high-speed data transmission and low-power-consumption long endurance, and the user experience of the Bluetooth device is effectively improved.

In some embodiments, the bluetooth device may pre-store a service identification associated with a service that requires high-speed transmission of a large amount of data. For example, a service identity repository may be established, which comprises at least one service identity. After the bluetooth device acquires the current service identifier, the current service identifier is compared with the service identifiers in the service identifier library, and if the service identifier library covers the current service identifier, the bluetooth device can determine that the service corresponding to the current service identifier is not a service with a large data stream, and does not need to use a traditional bluetooth device to transmit the data of the service corresponding to the current service identifier.

The bluetooth device may be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

Based on the established bluetooth connection, short-distance data interaction can be realized between the bluetooth device 101 and the electronic device 102.

In some embodiments, the processor 1013 may control the conventional bluetooth apparatus 1012 to power down and disconnect the second bluetooth connection between the conventional bluetooth apparatus 1012 and the electronic device 102 when it determines that there is no first service. When the processor 1013 determines that there is the first service, the conventional bluetooth apparatus 1012 may be controlled to be powered on, and the conventional bluetooth apparatus 1012 establishes a second bluetooth connection with the electronic device 102.

Based on the connection data, the smart watch can be automatically paired with the electronic device without configuring a connection therebetween, such as performing legitimacy verification and the like. The bluetooth address may be a Media Access Control (MAC) address.

The sensor 203 may be a distance sensor or a proximity light sensor. The processor 201 of the smart watch may determine whether it is worn by the user through the sensor 203. For example, the processor 201 of the smart watch may utilize a proximity light sensor to detect whether an object is near the smart watch, thereby determining whether the smart watch is worn by the user. Upon determining that the smart watch is worn, the processor 201 of the smart watch may turn on the receiver 204. In some embodiments, the smart watch may further include a bone conduction sensor, incorporated into a bone conduction headset.

The microphone 205, which may also be referred to as a "microphone," is used to convert sound signals into electrical audio signals. For example, when the smart watch is used as an audio input device of the electronic device 102, the microphone 205 may collect a voice signal of the user and convert the voice signal into an audio electrical signal when the user speaks (e.g., calls or sends a voice message). The audio electrical signal is the audio data in this embodiment.

In other embodiments, the bluetooth low energy device of the bluetooth apparatus may send a conventional bluetooth setup request message to the handset over the first bluetooth connection. The mobile phone receives a traditional Bluetooth establishment request message sent by a low-power Bluetooth device of the Bluetooth equipment through the first Bluetooth connection. Thus, the bluetooth device establishes a second bluetooth connection with the handset.

s406, the traditional Bluetooth device of the Bluetooth equipment transmits the data of the first service with the mobile phone through the second Bluetooth connection.

After the bluetooth device and the mobile phone establish the second bluetooth connection, the mobile phone can select to transmit the data of the first service through the traditional bluetooth device of the bluetooth device and the second bluetooth connection according to the identifier of the first service, so as to realize the high-speed transmission of the data of the first service.

And S407, the processor of the Bluetooth device determines that the first service transmission is finished, and controls the traditional Bluetooth device to be powered down.

In some embodiments, when the bluetooth device determines that the data of the first service has been transmitted, the bluetooth device may determine that the transmission of the first service is finished. The processor of the Bluetooth device can control the traditional Bluetooth device to be powered off, namely, the traditional Bluetooth device is stopped to be powered on, so that the traditional Bluetooth device stops working, and the second Bluetooth connection established between the traditional Bluetooth device and the mobile phone is disconnected. And the mobile phone detects that the connection with the traditional Bluetooth device is overtime, and disconnects the second Bluetooth connection with the traditional Bluetooth device of the Bluetooth equipment.

In other embodiments, the bluetooth device may determine that the first traffic transmission is terminated based on the received message. As shown in fig. 6, the bluetooth device determining that the first traffic transmission is ended may include the following steps.

S4072, the conventional bluetooth apparatus of the bluetooth device receives an end message of the first service sent by the mobile phone.

S4073, the processor of the Bluetooth device determines that the first service transmission is finished, and controls the traditional Bluetooth device to power down.

According to the Bluetooth switching method provided by the embodiment of the application, the Bluetooth equipment can keep a first Bluetooth connection with the mobile phone through the low-power Bluetooth device, so that low-power standby is realized, and a small amount of data is transmitted through the first Bluetooth connection; when a service request of a large data stream exists, the connection is automatically switched to the second Bluetooth connection, and high-speed data transmission can be realized through the second Bluetooth connection. Therefore, the Bluetooth device can realize high-speed data transmission and low-power-consumption long endurance, and the user experience of the Bluetooth device is effectively improved.

The Bluetooth device is a smart watch, and the Bluetooth headset comprises a processor, a low-power Bluetooth device and a traditional Bluetooth device. The electronic device is a mobile phone as an example, and a bluetooth switching method is exemplified.

The user can click the MAC address of the smart watch or a connection key corresponding to the MAC address of the smart watch, the mobile phone responds to the click operation, and the mobile phone and the smart watch establish second Bluetooth connection and first Bluetooth connection. For a specific interface schematic, reference may be made to the description of fig. 5A, which is not repeated. If the processor of the smart watch determines that the first service does not exist, the processor of the smart watch controls the traditional Bluetooth device to power down, and the traditional Bluetooth device of the smart watch is disconnected from the second Bluetooth connection established with the mobile phone. When a user drives a vehicle, the mobile phone of the user receives a voice call, the mobile phone transmits audio data of the voice call to the low-power-consumption Bluetooth device of the smart watch through the first Bluetooth connection, after the low-power-consumption Bluetooth device of the smart watch receives the audio data of the voice call, a processor of the smart watch determines that a voice call service is started, the processor of the smart watch controls a traditional Bluetooth device to be powered on, and the traditional Bluetooth device and the mobile phone establish a second Bluetooth connection. Subsequently, after the user answers the voice call, the traditional bluetooth device of the smart watch and the mobile phone can transmit voice call data through the second bluetooth connection. After the user directly hangs up the voice call without answering the voice call, or the user answers the voice call to carry out conversation and then hangs up the voice call, the processor of the smart watch determines that the voice conversation service transmission is finished, the processor of the smart watch controls the traditional Bluetooth device to be powered down, then the second Bluetooth connection reconstructed with the mobile phone is disconnected, and the first Bluetooth connection with the mobile phone is kept.
