Multi-Bluetooth interaction method and system for Android system

Abstract

The invention provides a multi-Bluetooth interaction method and system for an Android system, and the method comprises the steps that: an extended Bluetooth service (Bluetooth Ext apk) is added on the basis of an original Bluetooth apk of the Android; on the basis of an Android native FW interface android.Bluetooth, an expansion interface package Bluetooth is added, then an AIDL service interface of Bluetooth communication is expanded into an interface file of an Ext type, the service of an expansion Bluetooth process Bluetooth is started through the expanded Bluetooth Manager ServiceExt, an expansion Bluetooth module is newly added on the basis of a native blocking module, and therefore the requirement for simultaneous interaction of multiple Bluetooth modules is met, and due to the compatible design, the development efficiency is further improved, and the development cost is saved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a multi-bluetooth interaction method and system for an Android system. Background technique [0002] In the car entertainment system, the functions of bluetooth phone and bluetooth earphone have received more and more people's attention and love. At present, in the framework design and protocol stack design of the Android system, only one Bluetooth module can be supported. This solution has the following defects: first, it cannot support multiple Bluetooth modules to work at the same time. For example, in a multi-screen entertainment system, the main The driver needs to use the main Bluetooth module to connect to the mobile phone to operate the phone function, while the co-pilot or the rear passenger needs to use the second Bluetooth module to connect the headset to listen to the car audio for entertainment interaction. The design scheme of the existing bluetooth ...

Problems solved by technology

At present, in the framework design and protocol stack design of the Android system, only one Bluetooth module can be supported. This solution has the following defects: first, it cannot support multiple Bluetooth modules to work at the same time. For example, in a multi-screen entertainment system, the main The driver needs to use the main Bluetooth module to connect to the mobile phone for phone function operations, while the co-pilot or rear passengers need to use the second Bluetooth module to connect to the headset to listen to the audio of the car machine for entertainment interaction

The design scheme of the existing Android system Bluetooth framework cannot meet the requirements

Second, modifying the existing Bluetooth service framework and protocol stack framework of Android to support multiple Bluetooth modules in the car, the workload is very large, almost unacceptable, and the modification will lead to incompatibility of the Android version
