Description

蓝牙数据封装通信方法及装置 技术领域
本公开涉及无线通信技术领域，具体涉及一种蓝牙数据封装通信方法、装置、电子设备及存储介质。
背景技术
为了满足不同场景下不同程度的应用需求，移动通讯技术演化出了多个技术分支，比如为适应远距离大范围无线通信的3G、4G、5G蜂窝网络，为适应中等距离接入的WIFI技术，以及为适应短距离通信的蓝牙技术。由于每种通信技术的具体实现方式存在着本质的差异，只能在特定的软硬件的支持下才可组网通信，因此用户设备每多支持一种通信方式就需要增设相应的硬件单元和软件模块，对设备成本有极为明显的影响。
为控制成本，现有技术往往会根据用户依赖程度来设计用户设备，仅在较为核心的用户终端设备中集成多种通用通信模块，而在周边设备中仅根据典型应用场景采用一种通信模块。比如，用户手机通常会集成蜂窝通信、WIFI和蓝牙等多种通信模式；PAD或笔记本等移动终端则通常会集成WIFI和蓝牙模块；而手环、手表、耳机、音箱等智能硬件则往往只会保留蓝牙模块，使用时作为周边设备与核心设备建立蓝牙连接。通过这种方式，可以有效控制设备的硬件成本，减轻用户负担。
然而，发明人在实现本公开实施例相关技术方案的过程中发现，现有技术中通用的蓝牙连接方式给周边设备的定位过低，作为从设备接入时没有任何控制权限，只能通过主设备中的特定应用程序(App)来被动接受用户的输入控制，给用户和系统设计均带来了不小的麻烦。举例来说，为了降低移动POS机的硬件成本，现有技术中出现了无需SIM卡不带蜂窝通信模块的mPOS(Mobile Point of Sale)机，一般通过蓝牙模块作为从设备与用户手机 连接。在使用过程中，第一用户(通常为收款方)只能使用手机中的特定App来向mPOS机下发具体的设置信息；第二用户(通常为付款方)在mPOS机刷卡后，由于mPOS机不具备访问互联网的能力，只能将数据发给手机，由手机与服务器后台完成报文交换；同样地，第二用户的签名也只能在手机的特定App中完成。上述整个过程mPOS机更像是个读卡器，并未给用户带来更多的便捷，相反由于操作过程繁琐，同时特定App的开发、运营和维护的工作量大，反而给用户和供应商带来了更大的压力。

在蓝牙通信网络中，蓝牙连接两端的设备会被分别设置为主设备和从设备，主设备具有绝对的控制权，而从设备通常只能被动收发文件，这大大限制了蓝牙从设备的能力扩展，无法给用户带来更多的便利。
有鉴于此，本公开实施例提供了一种蓝牙数据封装通信方法，通过主从设备的动态切换，将蓝牙数据封装成TCP报文传输，使只具备蓝牙通信能力的周边设备可有效调用核心设备的3G/4G/5G网络，从而简化用户操作、降低系统设计的复杂度。在本公开的一个实施例中，如图1A所示，所述蓝牙数据封装通信方法包括：
S101，设置本次交易信息，接收用户刷卡信息，进行TCP封装和BNEP封装生成蓝牙数据组包；
S102，根据蓝牙数据组包发起BNEP连接请求，作为主设备与第一终端建立BNEP连接；
S103，通过BNEP连接调用第一终端的移动通信模块，将蓝牙数据组包中TCP封装的本次交易信息和用户刷卡信息通过互联网发送给后台服务器；
S104，通过第一终端接收后台服务器返回的结果信息；
S105，根据接收并解析后得到的结果信息确认本次交易完成。
上述方法从不具备其他通信能力的蓝牙周边设备(通常作为蓝牙连接中的从设备)出发，描述了其借助第一终端的移动通信模块实现互联网访问的过程。当然，本领域技术人员应当可以理解，本公开实施例的技术方案是一个多设备交互的通信方法，每个设备有其各自对应的数据处理过程，上述蓝牙周边设备单侧处理过程的描述不应视作对本公开技术方案实现的具体限制。进一步地，参见图1B，在本公开的一个优选实施例中，以mPOS机刷卡的应用场景为例，更详尽地描述了一次完整的任务处理过程中的通信方法：
mPOS机开机启动，第一终端搜索蓝牙配对设备，mPOS机作为从设备与第一终端建立通用蓝牙连接。其中，第一终端优选为手机，但其他同时具备蓝牙和互联网通信能力的设备(比如PAD、笔记本电脑等)均可适用于本公开的实施例中，故在此不对第一终端的类型做出更具体的限制。两设备的蓝牙连接在初次连接时可能需要初始化，需要用户手动选择设备并确认；在成功建立第一次连接之后，后续的再次连接可由两设备自动完成，无需用户介入。
mPOS机设置本次交易信息，接收用户刷卡信息，进行TCP封装和BNEP封装生成蓝牙数据组包；
根据蓝牙数据组包发起BNEP连接请求，mPOS机切换为主设备与第一终端建立BNEP连接；
通过BNEP连接调用第一终端的移动通信模块，将蓝牙数据组包中TCP封装的本次交易信息和用户刷卡信息通过互联网发送给后台服务器。
第一终端的移动通信模块接收后台服务器返回的TCP封装的结果信息，添加BNEP封装后通过BNEP连接发送给mPOS机。更进一步地，mPOS机可能会与第一终端及后台服务器有多次交互，接收交易结果信息后，再由支付用户在mPOS机上手写签名；对签名信息进行TCP封装和BNEP封装，重复之前的数据发送和接收过程，从后台服务器接收对签名信息的处理结果信息，再由第一终端传输给mPOS机。
mPOS机经解析后得到结果信息，确认本次交易完成(成功或失败)。 对于交易成功完成的，可按需打印交易小票，结束全部交易过程；对于交易失败的，通知用户，结束本次交易，在需要时可再次发起交易操作。
其中，BNEP(Bluetooth Network Encapsulation Protocol，蓝牙网络封装协议)为标准的蓝牙协议组件，其协议网络架构如图2所示。具体地，BNEP协议上层的网络应用层主要通过TCP协议或UDP协议封装和处理数据，通过IP协议进行数据传输；而中间层通过BNEP封装将TCP报文封装为蓝牙支持的格式，最后通过底层的蓝牙通信模块(包括但不限于蓝牙基带和蓝牙射频等)将数据传输给另一个蓝牙设备。
更具体地，mPOS机通过交易线程和后台线程两个线程来管理和实现上述过程；其中，交易线程负责应用层的数据处理，后台线程负责底层的蓝牙通信。在上述通信方法中，后台线程负责从蓝牙串口接收蓝牙数据，按照蓝牙协议解析，如果解析到具体的连接设置信息，就设置对应的连接状态；如果解析收到TCP数据，则将TCP数据放入缓冲区，等待协议上层的交易线程获取使用。而交易线程负责上层的数据处理，比如根据交易信息确定要连接BNEP，TCP封装信息，发起TCP连接发送数据(后续由后台线程完成蓝牙交互)；以及接收缓冲区的TCP数据，解析处理数据获得结果信息、确认交易等。而手机终端中，在接收到mPOS机的蓝牙数据、解析得到TCP数据后，并不向上层的网络应用层提供数据(因为本公开实施例中手机终端并不存在类似的上层App应用)，而是直接通过移动通信模块将TCP数据转发给互联网另一端的后台服务器；收到后台服务器返回的TCP数据后，同样不在手机终端本地处理，而是进行BNEP封装后通过蓝牙通信模块发送给mPOS机。通过这种方式，本公开的实施例中手机终端完全无需设计开发特定的App，原先由App完成的工作都分散给mPOS机和两终端后台完成，降低了系统开发的复杂度，进一步降低了整体成本。
在本公开的一个实施例中，在用户前端，可以仅通过mPOS机的界面完成全部操作。如图3的用户界面变化图所示，第一用户(通常为收款方)首先在mPOS机中选择操作类型，随后设置本次交易信息；第二用户(通常为 付款方)在mPOS机刷卡，并相应输入该卡的交易密码；mPOS机在后端完成数据交互，接收到交易结果信息后，再由第二用户在mPOS机手写签名；mPOS机在后端再次完成数据交互，接收到签名处理结果信息后，确认本次交易成功。
采用这种方式，用户在前端只通过mPOS机即可完成全部流程，无需在mPOS机和商户手机终端两个设备之间来回切换；同时只具备蓝牙通信模块的mPOS机也可主动完成互联网交互，无需专门针对商户手机终端开发特定App，因而本公开的实施例实现了低成本mPOS机快捷便利的应用，进一步降低了系统开发和维护成本，增强了用户体验。
以上方法步骤是从mPOS机刷卡的应用场景出发进行描述，本领域技术人员应当可以理解，本公开的实施例显然也可适用于其他交互场景，比如智能手表、蓝牙音箱、智能眼镜、智能手环等设备的互联网访问场景，故上述方法步骤不应视为对本公开实施例具体执行设备的限制。
根据本公开实施例所提出的蓝牙数据封装通信方法，可以使只具备蓝牙通信能力的传统蓝牙从设备可以在不增加软硬件成本的情况下实现互联网访问能力，因而有效提升了设备适用性，实现了快捷便利的操作，改善了用户体验。
