[0032] Embodiment One

[0033] Fig. 1 is a flowchart of a Bluetooth chip adaptation method according to Embodiment One of the present application. The present embodiment can be applied to the case of Bluetooth protocol stack adaptation for a target vehicle-mounted Bluetooth chip. The method can be executed by a Bluetooth chip adaptation apparatus, which can be implemented in the form of hardware and / or software.

[0034] As shown in Fig. 1, the method includes:

[0035] S101, obtaining a chip adaptation request for a target vehicle-mounted Bluetooth chip, and determining a standardized interface corresponding to the chip adaptation request.

[0036] In the embodiment, the target vehicle-mounted Bluetooth chip can be understood as a Bluetooth chip to be adapted and connected, and the target vehicle-mounted Bluetooth chip is applied to a vehicle. The chip adaptation request can be understood as a request for adapting the protocol stack for the target vehicle-mounted Bluetooth chip, and the chip adaptation request includes at least one of the Bluetooth function, the Bluetooth specification, the Bluetooth version and the required Bluetooth protocol stack type required by the client, or directly includes a specified Bluetooth protocol stack. The chip adaptation request is obtained through an upper application, which can be understood as an application interacting with a user. The standardized interface can be understood as an application programming interface (API) for connecting with a library file calling the protocol stack software, and in the embodiment, the standardized interface is connected with an adaptation layer, and defines an interaction mode between the upper application and the adaptation layer.

[0037] For example, the chip adaptation request for the target vehicle-mounted Bluetooth chip is obtained, and based on the Bluetooth function, the Bluetooth version, the protocol stack type and other information contained in the chip adaptation request, the target Bluetooth protocol stack satisfying the above content is determined, or when the chip adaptation request directly includes a specified Bluetooth protocol stack, the specified Bluetooth protocol stack is taken as the target Bluetooth protocol stack, and the target Bluetooth protocol stack is the Bluetooth protocol stack to be connected and driven with the target vehicle-mounted Bluetooth chip in the embodiment. Each Bluetooth protocol stack has its predefined standardized interface, and after the target Bluetooth protocol stack is determined, the standardized interface corresponding to the target Bluetooth protocol stack is determined based on the correspondence between each Bluetooth protocol stack and each standardized interface.

[0038] In the embodiment, the adaptation layer can be understood as a layer for connecting the upper application and the protocol stack software, and the adaptation layer usually contains necessary library files and configurations to support specific Bluetooth protocol stacks and functions. The target library file can be understood as a library file corresponding to the chip adaptation request and the standardized interface contained in the adaptation layer, and the target library file at least includes the Bluetooth protocol stack code capable of realizing the function required by the chip adaptation request or the Bluetooth protocol stack code specified by the chip adaptation request. The library file at least includes a shared library (so library) and a Java archive file (Jar library).

[0039] In the embodiment, the adaptation layer can be understood as a layer for connecting the upper application and the protocol stack software, and the adaptation layer usually contains necessary library files and configurations to support specific Bluetooth protocol stacks and functions. The target library file can be understood as a library file corresponding to the chip adaptation request and the standardized interface contained in the adaptation layer, and the target library file at least includes the Bluetooth protocol stack code capable of realizing the function required by the chip adaptation request or the Bluetooth protocol stack code specified by the chip adaptation request. The library file at least includes a shared library (so library) and a Java archive file (Jar library).

[0040] The standardized interface accesses an adaptation layer matching the type of the standardized interface, for example, when the standardized interface is a native interface, the adaptation layer corresponding to the native interface is accessed, and a target library file corresponding to the chip adaptation request and the standardized interface is loaded or updated in the adaptation layer. The target library file is determined based on the language type and content of the chip adaptation request, and the target library file matching the language type and content of the chip adaptation request is determined from a library file set. The target library file can be an so library, a jar library, or other types of library files, which are not limited in the embodiment.

[0041] When the target vehicle-mounted Bluetooth chip is not connected to any Bluetooth protocol stack, the target library file is directly loaded in the adaptation layer; when the target vehicle-mounted Bluetooth chip is currently connected to a Bluetooth protocol stack, the library file corresponding to the chip adaptation request is used as the target library file to update the adaptation layer library file.

[0042] The above technical solution loads the target library file into the memory by dynamic loading or static linking, so that the adaptation layer can respond to the request of the upper application according to the function provided by the standardized interface.

[0043] S103, calling a target Bluetooth protocol stack corresponding to the chip adaptation request through the target library file.

[0044] In the embodiment, the target Bluetooth protocol stack can be understood as a Bluetooth protocol stack meeting the requirements of the chip adaptation request, for example, a Bluetooth protocol stack meeting at least one of the Bluetooth functions, Bluetooth specifications, Bluetooth versions, and Bluetooth protocol stack types included in the chip adaptation request, or a Bluetooth protocol stack directly specified by the chip adaptation request.

[0045] For example, the target library file contains the codes of multiple Bluetooth protocol stacks, and the target Bluetooth protocol stack is known when the chip adaptation request is obtained, so the code of the target Bluetooth protocol stack is directly called from the target library file.

[0046] S104, connecting the target vehicle-mounted Bluetooth chip through the target Bluetooth protocol stack.

[0047] In the embodiment, the corresponding protocol stack software is connected through the interface corresponding to the target Bluetooth protocol stack, the protocol stack software is used as a driver, and the target vehicle-mounted Bluetooth chip is connected to realize the calling of the target vehicle-mounted Bluetooth chip.

[0048] FIG. 2 is a schematic diagram of the overall interaction involved in a Bluetooth chip adaptation method provided by the embodiment, as shown in FIG. 2, the upper application applies the target library file through the adaptation layer, calls the target Bluetooth protocol stack through the target library file, and connects the Bluetooth chip through the protocol stack software of the target Bluetooth protocol stack to realize the adaptation and calling of the Bluetooth chip.

[0049] The Bluetooth chip adaptation method provided in the embodiments of the present application comprises: obtaining a chip adaptation request for a target vehicle-mounted Bluetooth chip, and determining a standardized interface corresponding to the chip adaptation request; accessing a corresponding adaptation layer based on the standardized interface and determining a target library file of the adaptation layer, wherein the target library file is obtained by loading or updating based on the chip adaptation request; calling a target Bluetooth protocol stack corresponding to the chip adaptation request through the target library file; and connecting with the target vehicle-mounted Bluetooth chip through the target Bluetooth protocol stack. The above technical solution introduces the concept of an adaptation layer, loads a library file in the adaptation layer, and when adding, modifying or replacing a library file caused by changes in a protocol stack occurs, only corresponding adjustment of the library file in the adaptation layer is needed, without the need to recompile the entire program, and the upper-layer application does not need to be modified, thereby realizing decoupling of the upper-layer application and the protocol stack software, realizing flexible switching of the protocol stack when the Bluetooth chip is applied, and reducing the research and development and maintenance costs.

[0050] Embodiment Two

[0051] FIG. 3 is a flowchart of a Bluetooth chip adaptation method provided in Embodiment Two of the present application. This embodiment is a further optimization of any of the above embodiments, and can be applied to the case of adapting a Bluetooth protocol stack for a target vehicle-mounted Bluetooth chip. The method can be executed by a Bluetooth chip adaptation device, which can be implemented in the form of hardware and / or software.

[0052] As shown in FIG. 3, the method comprises:

[0053] S201: Obtain a chip adaptation request for a target vehicle-mounted Bluetooth chip.

[0054] S202: Determine a target Bluetooth protocol stack corresponding to the chip adaptation request.

[0055] In this embodiment, the chip adaptation request comprises at least one of a required Bluetooth function, a Bluetooth specification, a Bluetooth version and a required Bluetooth protocol stack type, or directly comprises a specified Bluetooth protocol stack. Therefore, the matching Bluetooth protocol stack can be directly determined based on the requirements corresponding to the chip adaptation request.

[0056] For example, when the chip adaptation request comprises a required Bluetooth function, a Bluetooth specification, a Bluetooth version and a Bluetooth protocol stack type, a Bluetooth protocol stack matching all of the required Bluetooth function, the Bluetooth specification, the Bluetooth version and the Bluetooth protocol stack type is determined as the target Bluetooth protocol stack; or when the chip adaptation request comprises a specified Bluetooth protocol stack, the specified Bluetooth protocol stack is determined as the target Bluetooth protocol stack.

[0057] S203: Determine a standardized interface corresponding to the chip adaptation request based on a predefined correspondence between the target Bluetooth protocol stack and the standardized interface.

[0058] In the embodiment, the standardized interface includes at least a native interface, an extended interface and a custom interface. The native interface is a native interface provided by Google. The extended interface is a native interface with specific functions added on the basis of the native interface. The custom interface is a brand-new native interface, and is related to functions corresponding to actual needs of a user. Different Bluetooth protocol stack providers, some of which adapt the native interface, some of which have mature custom interfaces, and some of which have extended interfaces based on the native interface. Different Bluetooth protocol stacks are from different protocol stack providers. The Bluetooth protocol stack, the provider and the standardized interface have a predefined two-to-two corresponding relationship.

[0059] Based on the protocol stack provider attribute of the target Bluetooth protocol stack, the protocol stack provider of the target Bluetooth protocol stack is determined, and then the standardized interface corresponding to the protocol stack provider is determined.

[0060] FIG. 4 is a schematic diagram of selection of a standardized interface involved in a Bluetooth chip adaptation method according to Embodiment Two of the present application. As shown in FIG. 4, an upper-layer application accesses an adaptation layer through a standardized interface. The standardized interface is one of a native interface (Google Native), an extended interface (Google+Custom Native) and a custom interface (Custom Native).

[0061] S204, based on the standardized interface, the corresponding adaptation layer is accessed, and a target library file corresponding to the chip adaptation request is determined.

[0062] FIG. 5 is a schematic diagram of selection of an adaptation layer library file involved in a Bluetooth chip adaptation method according to Embodiment Two of the present application. As shown in FIG. 5, taking a so library as an example, an upper-layer application determines a corresponding adaptation layer based on a standardized interface. The three adaptation layers shown in FIG. 5 are a native adaptation layer (libbluetooth_jni.so) corresponding to a native interface, an extended adaptation layer corresponding to an extended interface and a custom adaptation layer corresponding to a custom interface. The adaptation layer corresponding to the type of the standardized interface is determined.

[0063] For example, when the standardized interface is a native interface, the native interface is used to access a native adaptation layer, where the native adaptation layer is used to store a protocol stack library file of a protocol stack provider corresponding to the native interface; when the standardized interface is an extended interface, the extended interface is used to access an extended adaptation layer, where the extended adaptation layer is used to store a protocol stack library file of a protocol stack provider corresponding to the extended interface; when the standardized interface is a custom interface, the custom interface is used to access a custom adaptation layer, where the custom adaptation layer is used to store a protocol stack library file of a protocol stack provider corresponding to the custom interface. After accessing the corresponding adaptation layer, the target library file to be loaded or updated is determined based on the target Bluetooth protocol stack corresponding to the chip adaptation request.

[0064] Optionally, the target library file corresponding to the chip adaptation request is determined, and the method comprises the following steps.

[0065] S2041, determining a target Bluetooth protocol stack corresponding to the chip adaptation request.

[0066] In this embodiment, the content of the target Bluetooth protocol stack corresponding to the chip adaptation request is determined, which is consistent with the above step S202, and will not be described here.

[0067] S2042, determining a target library file containing a code of the target Bluetooth protocol stack corresponding to a language of the chip adaptation request from the library file set.

[0068] In this embodiment, the chip adaptation request can correspond to a C language, such as C language or C++ language, or can correspond to a Java virtual machine language (JVM), such as Java, Kotlin, Scala, Groovy, etc. When the chip adaptation request is a C language, a shared library (so library) containing a code of the target Bluetooth protocol stack is determined from the library file set as the target library file; when the chip adaptation request is a Java virtual machine language, a Java archive file (Jar library) containing a code of the target Bluetooth protocol stack is determined from the library file set as the target library file.

[0069] FIG. 6 is a schematic diagram of an adaptation layer application involved in a Bluetooth chip adaptation method according to Embodiment Two of the present application; as shown in FIG. 6, if the library file is directly determined to be a so library, but the language corresponding to the chip adaptation request is a Java virtual machine language, a Java native interface (Java Native Interface, JNI) is used to call Java code to form a target library file in a language corresponding to the chip adaptation request.

[0070] S205, determining whether the target vehicle-mounted Bluetooth chip is currently applying a Bluetooth protocol stack.

[0071] In the embodiment, it is determined whether the target vehicle-mounted Bluetooth chip is currently driven by the Bluetooth protocol stack, or it is determined whether the library file is contained in the adaptation layer accessed based on the standardized interface, if yes, it is determined that the target vehicle-mounted Bluetooth chip is applying the Bluetooth protocol stack, otherwise, the target vehicle-mounted Bluetooth chip is not applying the Bluetooth protocol stack.

[0072] In S206, if the target vehicle-mounted Bluetooth chip is not applying the Bluetooth protocol stack, the target library file is loaded in the adaptation layer.

[0073] In the embodiment, if the target vehicle-mounted Bluetooth chip is not applying the Bluetooth protocol stack, the target library file corresponding to the chip adaptation request (or the target Bluetooth protocol stack) can be directly loaded in the adaptation layer at this time.

[0074] In S207, if the target vehicle-mounted Bluetooth chip is applying the Bluetooth protocol stack, the target library file is updated in the adaptation layer according to the current Bluetooth protocol stack being applied by the target vehicle-mounted Bluetooth chip and the target Bluetooth protocol stack corresponding to the chip adaptation request.

[0075] In the embodiment, if the target vehicle-mounted Bluetooth chip is applying the Bluetooth protocol stack, the chip adaptation request at this time can be understood as a protocol stack replacement request, and it is needed to judge whether the target library file needs to be updated in the adaptation layer based on the target Bluetooth protocol stack to be applied according to the current Bluetooth protocol stack being applied by the target vehicle-mounted Bluetooth chip.

[0076] Optionally, if the target vehicle-mounted Bluetooth chip is applying the Bluetooth protocol stack, the target library file is updated in the adaptation layer according to the current Bluetooth protocol stack being applied by the target vehicle-mounted Bluetooth chip and the target Bluetooth protocol stack corresponding to the chip adaptation request, including:

[0077] In S2071, if the current Bluetooth protocol stack being applied by the target vehicle-mounted Bluetooth chip and the target Bluetooth protocol stack corresponding to the chip adaptation request have the same protocol stack supply attribute, the current library file currently applied by the adaptation layer is taken as the target library file.

[0078] In the embodiment, the current Bluetooth protocol stack can be understood as the Bluetooth protocol stack being adopted by the Bluetooth chip at the current time. The protocol stack supply attribute can be understood as attribute information used for representing the source supply of the Bluetooth protocol stack. When the protocol stack supply attributes of two Bluetooth protocol stacks are consistent, it represents that the two Bluetooth protocol stacks are from the same protocol stack supply. The current library file can be understood as the library file corresponding to the current Bluetooth protocol stack applied by the adaptation layer when the target vehicle-mounted Bluetooth chip adopts the current Bluetooth protocol stack at the current time.

[0079] For example, if the same protocol stack provider provides the same library file, if the current Bluetooth protocol stack applied by the target vehicle Bluetooth chip and the target Bluetooth protocol stack corresponding to the chip adaptation request have the same protocol stack supply attribute, it indicates that the current Bluetooth protocol stack and the target Bluetooth protocol stack come from the same protocol stack provider, at this time, the current library file applied by the adaptation layer also includes the code of the target Bluetooth protocol stack, and the calling of the target Bluetooth protocol stack can be realized. Therefore, when the current Bluetooth protocol stack and the target Bluetooth protocol stack have the same protocol stack supply attribute, the current library file applied by the adaptation layer is directly used as the target library file, and it is assumed that the updating of the library file has been completed, and the updating of the library file does not need to be actually performed.

[0080] S2072, if the current Bluetooth protocol stack applied by the target vehicle Bluetooth chip and the target Bluetooth protocol stack corresponding to the chip adaptation request have different protocol stack supply attributes, updating the current library file applied by the adaptation layer to the target library file corresponding to the target Bluetooth protocol stack.

[0081] In the embodiment, if the current Bluetooth protocol stack applied by the target vehicle Bluetooth chip and the target Bluetooth protocol stack corresponding to the chip adaptation request have different protocol stack supply attributes, it indicates that the current Bluetooth protocol stack and the target Bluetooth protocol stack come from different protocol stack providers, and different protocol stack providers correspond to different library files, and the current library file applied by the adaptation layer cannot realize the calling of the target Bluetooth protocol stack code. Therefore, when the current Bluetooth protocol stack and the target Bluetooth protocol stack have different protocol stack supply attributes, the current library file applied by the adaptation layer is deleted, and the target library file corresponding to the chip adaptation request (or the target Bluetooth protocol stack) determined in step S204 is loaded, so as to realize the updating of the library file in the adaptation layer.

[0082] S208, calling the target Bluetooth protocol stack corresponding to the chip adaptation request through the target library file.

[0083] S209, calling the target protocol stack software of the target Bluetooth protocol stack through the protocol stack interface provided by the target Bluetooth protocol stack, and connecting the target vehicle Bluetooth chip through the target protocol stack software.

[0084] In the embodiment, the target protocol stack software can be understood as the protocol stack software corresponding to the target Bluetooth protocol stack, and is used to realize the connection and driving of the target vehicle Bluetooth chip.

[0085] Exemplarily, the target protocol stack software of the target Bluetooth protocol stack is connected through the protocol stack interface provided by the target Bluetooth protocol stack, the target protocol stack software is called to be connected with the target vehicle-mounted Bluetooth chip, and the calling and driving of the target Bluetooth chip are realized through the target protocol stack software. The protocol stack interface provided by the target Bluetooth protocol stack is related to the language corresponding to the chip adaptation request. When the language corresponding to the chip adaptation request is a C language, the target Bluetooth protocol stack provides a C / C++ interface. When the language corresponding to the chip adaptation request is a Java virtual machine language, the target Bluetooth protocol stack provides a Java / kotlin interface.

[0086] As shown in FIG. 6, the corresponding interface is called based on the language type of the target library file. When the target library file is an so library, the target Bluetooth protocol stack is called through a C++ interface, and the target protocol stack software is called through the C / C++ interface of the target Bluetooth protocol stack. When the target library file is a jar library determined after the JNI is called back to the Java layer, the target Bluetooth protocol stack is called through Java, and the target protocol stack software is called through the Java / Kotlin interface of the target Bluetooth protocol stack.

[0087] The Bluetooth chip adaptation method provided by the embodiment includes obtaining a chip adaptation request for a target vehicle-mounted Bluetooth chip; determining a target Bluetooth protocol stack corresponding to the chip adaptation request; determining a standardized interface corresponding to the chip adaptation request based on a predefined correspondence relationship between the target Bluetooth protocol stack and the standardized interface; accessing a corresponding adaptation layer based on the standardized interface, and determining a target library file corresponding to the chip adaptation request; determining whether the target vehicle-mounted Bluetooth chip is applying a Bluetooth protocol stack; if the target vehicle-mounted Bluetooth chip is not applying the Bluetooth protocol stack, loading the target library file in the adaptation layer; if the target vehicle-mounted Bluetooth chip is applying the Bluetooth protocol stack, updating the target library file in the adaptation layer according to a current Bluetooth protocol stack being applied by the target vehicle-mounted Bluetooth chip and the target Bluetooth protocol stack corresponding to the chip adaptation request; calling the target Bluetooth protocol stack corresponding to the chip adaptation request through the target library file; calling target protocol stack software of the target Bluetooth protocol stack through a protocol stack interface provided by the target Bluetooth protocol stack, and connecting the target protocol stack software with the target vehicle-mounted Bluetooth chip. The above technical solution introduces the concept of the adaptation layer, loads the library file in the adaptation layer, and only needs to make corresponding adjustments of the library file in the adaptation layer when adding, modifying or replacing the library file due to changes in the protocol stack, without the need to recompile the entire program. The upper-layer application does not need to be modified, the upper-layer application and the protocol stack software are decoupled, the flexible switching of the protocol stack is realized when the Bluetooth chip is applied, and the research and development and maintenance costs are reduced.
