Bluetooth connection method and related apparatus
A Bluetooth connection method and a related apparatus are disclosed, and relate to the field of short-range wireless communications technologies. A first electronic device establishes a BLE connection to a second electronic device, and exchanges data with the second electronic device based on a first connection interval. The first electronic device further establishes a BR/EDR connection to a third electronic device. When device class information of the second electronic device is the same as device class information prestored in a memory, the first electronic device exchanges data with the second electronic device based on a second connection interval. The second connection interval is greater than the first connection interval. In this way, a throughput speed of exchanging data by the third electronic device can be increased.
1. A first electronic device, wherein the first electronic device comprises:
a touchscreen, wherein the touchscreen comprises a touch-sensitive surface and a display;
one or more processors;
a Bluetooth chip, wherein the Bluetooth chip supports a classic Bluetooth BR/EDR function and a Bluetooth low energy BLE function;
a memory, wherein the memory stores a plurality of applications, and one or more computer programs, the one or more computer programs comprise instructions, and when the instructions are executed by the first electronic device, the first electronic device is enabled to perform the following steps:
establishing a BLE connection to a second electronic device, and exchanging data with the second electronic device based on a first connection interval, wherein the first connection interval is a first value;
establishing a BR/EDR connection to a third electronic device;
receiving a first user operation for playing audio;
adjusting the first connection interval to a second value, after the receiving, when data exchanged with the third electronic device is audio data, and the second value is greater than the first value.
2. The first electronic device according to claim 1 , wherein when the instructions are executed by the first electronic device, the first electronic device is enabled to further perform the following step:
when a codec format of the data exchanged with the third electronic device is one or more of LDAC, high-resolution wireless audio HWA, aptX HD, and advanced audio coding AAC, adjusting the first connection interval of the second electronic device to the second value.
3. The first electronic device according to claim 1 , wherein when the instructions are executed by the first electronic device, the first electronic device is enabled to further perform the following step:
adjusting the first connection interval of the second electronic device to a third value when the data exchanged with the third electronic device is empty data or a control signal, wherein the third value is less than the second value.
4. The first electronic device according to claim 3 , wherein before the data exchanged between the first electronic device and the third electronic device is the empty data or the control signal, when the instructions are executed by the first electronic device, the first electronic device is enabled to further perform the following step:
receiving a second user operation for pausing audio playback.
5. A Bluetooth connection method, wherein the method comprises:
establishing, by a first electronic device, a Bluetooth low energy BLE connection to a second electronic device, and exchanging data with the second electronic device based on a first connection interval, wherein the first connection interval is a first value; and
establishing, by the first electronic device, a classic Bluetooth BR/EDR connection to a third electronic device;
receiving, by the first electronic device, a first user operation for playing audio;
adjusting, by the first electronic device, the first connection interval to a second value, after the receiving, when data exchanged with the third electronic device is audio data, and the second value is greater than the first value.
6. The method according to claim 5 , wherein the adjusting, by the first electronic device, the first connection interval to a second value when data exchanged with the third electronic device is audio data comprises:
adjusting, by the first electronic device, the first connection interval to the second value when a codec format of the data exchanged with the third electronic device is one or more of LDAC, high-resolution wireless audio HWA, aptX HD, and advanced audio coding AAC.
7. The method according to claim 5 , wherein after the adjusting, by the first electronic device, the first connection interval to a second value when data exchanged with the third electronic device is audio data, the method further comprises:
adjusting, by the first electronic device, the first connection interval to a third value when the data exchanged with the third electronic device is empty data or a control signal, wherein the third value is less than the second value.
8. The method according to claim 7 , wherein before the adjusting, by the first electronic device, the first connection interval to a third value when the data exchanged with the third electronic device is empty data or a control signal, the method further comprises:
receiving, by the first electronic device, a second user operation for pausing audio playback.
