阅读说明：本技术 业务连接建立方法、蓝牙主设备、芯片及蓝牙系统 (Service connection establishing method, Bluetooth main device, chip and Bluetooth system ) 是由 刘秀华 牛永民 唐能福 于 2020-03-28 设计创作，主要内容包括：本申请提供一种业务连接建立方法、蓝牙主设备、芯片及蓝牙系统,蓝牙主设备扫描到包含至少两个蓝牙从设备的组合设备后,若需要蓝牙主设备与该组合设备中的各蓝牙从设备建立业务连接,则在配对阶段,蓝牙主设备与该组合设备中的一个蓝牙从设备完成配对后,自动与该组合设备中的另一个蓝牙从设备进行配对；同理,在在业务连接建立阶段,蓝牙主设备与该组合设备中的一个蓝牙从设备建立业务连接后,自动与该组合设备中的另一个蓝牙从设备建立业务连接。该过程中,无需逐个手动选择扫描到的蓝牙从设备,而是蓝牙主设备自动与各蓝牙从设备进行配对并建立业务连接,过程简单且业务连接建立速度快。(The application provides a service connection establishing method, a Bluetooth master device, a chip and a Bluetooth system, wherein after the Bluetooth master device scans a combined device comprising at least two Bluetooth slave devices, if the Bluetooth master device needs to establish service connection with each Bluetooth slave device in the combined device, in a pairing stage, after the Bluetooth master device finishes pairing with one Bluetooth slave device in the combined device, the Bluetooth master device automatically pairs with another Bluetooth slave device in the combined device; similarly, in the service connection establishment phase, after the bluetooth master device establishes service connection with one bluetooth slave device in the combined device, the bluetooth master device automatically establishes service connection with another bluetooth slave device in the combined device. In the process, the scanned Bluetooth slave devices do not need to be manually selected one by one, but the Bluetooth master device is automatically paired with each Bluetooth slave device and establishes service connection, the process is simple, and the service connection establishment speed is high.)
