The specific structure is shown in fig. 1, and comprises:
and the functional interface converter 101 is used for converting the functional interface of the android bluetooth in the bionic environment into a functional interface which can be called in the glibc environment.
Specifically, the functional interface translator 101 may also be referred to as an android shared library loader. As shown in fig. 2, the functional interface converter 101 includes: load module 1011, replace module 1012. The loading module 1011 is used for loading the shared library of the bionic environment in the glibc environment; the replacement module 1012 is configured to replace the interface function provided by the shared library of the bionic environment with the interface function provided by the glibc environment.
In a specific example, the functional interface converter 101 supports platforms such as ARM, MIPS, etc., and is not limited herein.

In a specific example, the command issuing module 103 operates using a message-driven model, and establishes an independent thread running environment during initialization. Then, a processing function table of the message, i.e. a message processing policy, is established, each entry in the table is a sequence pair, the first element is a message type, and the second element is a specific logical code, such as < SCAN, start _ inquiry >. After the communication module 102 sends the message to the command issuing module 103, the command issuing module 103 may search the logic code, i.e., the processing function, corresponding to the message in the message processing function table according to the type of the message.

The communication module 102 registers the underlying event handling function with the message monitoring module at startup, including enabling failure and enabling success, pairing success and pairing failure, connection success and connection failure, and the like, which is not limited herein. And after receiving the message from the hardware abstraction layer, distributing the message to the corresponding registration callback function according to the message type for processing. The received message from the hardware abstraction layer includes an execution result of a last issued command, a remote device requesting pairing, a remote device requesting connection, and the like, which is not limited herein. After the messages from the hardware abstraction layer are analyzed, the messages are distributed to the communication module 102 for processing according to different service scenes.
