为了更好的理解本申请实施例，对本申请实施例提供的蓝牙通信***进行介绍。请参见图1A，图1A是本申请实施例提供的一种蓝牙通信***的示意图。蓝牙通信***10可以包括广播设备100以及扫描设备200。其中：In order to better understand the embodiments of the present application, the Bluetooth communication system provided by the embodiments of the present application is introduced. Please refer to FIG. 1A . FIG. 1A is a schematic diagram of a Bluetooth communication system provided by an embodiment of the present application. The Bluetooth communication system 10 may include a broadcasting device 100 and a scanning device 200 . in:
广播设备100为非一直充电的功耗敏感设备，且具备BLE广播功能；例如，可以是智能手表、智能眼镜等智能穿戴终端设备，或电池容量小的终端设备。在蓝牙通信***中广播设备100的个数不做限制，可以为多个，图1A中以一个智能手表为例。扫描设备200，可以为移动终端、平板电脑、笔记本电脑、个人电脑等具备BLE扫描功能的电子设备。在蓝牙通信***中扫描设备200的个数不做限制，可以为多个，图1A中以一个移动终端为例。广播设备100和扫描设备200可以通过BLE进行连接。The broadcasting device 100 is a power consumption sensitive device that is not always charged, and has the BLE broadcasting function; for example, it may be a smart wearable terminal device such as a smart watch and smart glasses, or a terminal device with a small battery capacity. The number of broadcasting devices 100 in the Bluetooth communication system is not limited, and may be multiple. In FIG. 1A , a smart watch is used as an example. The scanning device 200 may be an electronic device with a BLE scanning function, such as a mobile terminal, a tablet computer, a notebook computer, and a personal computer. In the Bluetooth communication system, the number of scanning devices 200 is not limited, and may be multiple. In FIG. 1A , a mobile terminal is used as an example. The broadcasting device 100 and the scanning device 200 may be connected through BLE.
首先对现有技术中的数据信息的传输方法进行介绍。参见图1B，是本申请实施例提供的一种可被扫描的BLE广播报文的通信过程的示意图。广播设备100中的应用程序A启动广播，蓝牙通信模块A通过BLE发送通用广播指示(ADV_IND)等广播报文给扫描设备200。扫描设备200启动BLE扫描，扫描到广播报文后，可通过发送请求报文(SCAN_REQ)从广播设备100获取更多信息。广播设备100收到SCAN_REQ后，发送扫描响应报文(SCAN_RSP)携带响应信息给扫描设备200，扫描设备200可上报该SCAN_RSP给应用程序B。但是目前的蓝牙标准中，SCAN_REQ无法携带数据信息。因此，扫描设备200无法发送数据信息给广播设备100，该广播通信过程只能传输单向的数据信息。如果扫描设备200需要发送数据信息给广播设备100，则扫描设备200需额外增加BLE广播功能，广播设备100也需要增加BLE扫描功能，这种方式会增加设备的功耗。First, the data information transmission method in the prior art is introduced. Referring to FIG. 1B , it is a schematic diagram of a communication process of a scannable BLE broadcast message provided by an embodiment of the present application. The application A in the broadcasting device 100 starts broadcasting, and the Bluetooth communication module A sends broadcasting messages such as general broadcasting indication (ADV_IND) to the scanning device 200 through BLE. The scanning device 200 starts BLE scanning, and after scanning the broadcast message, it can obtain more information from the broadcast device 100 by sending a request message (SCAN_REQ). After receiving the SCAN_REQ, the broadcast device 100 sends a scan response message (SCAN_RSP) carrying the response information to the scan device 200 , and the scan device 200 can report the SCAN_RSP to the application B. However, in the current Bluetooth standard, SCAN_REQ cannot carry data information. Therefore, the scanning device 200 cannot send data information to the broadcast device 100, and the broadcast communication process can only transmit data information in one direction. If the scanning device 200 needs to send data information to the broadcasting device 100, the scanning device 200 needs to add the BLE broadcasting function, and the broadcasting device 100 also needs to add the BLE scanning function, which will increase the power consumption of the device.
参见图1C，是本申请实施例提供的一种BLE连接数据报文的通信过程的示意图。广播设备100(从设备Slave)通过BLE发送ADV_IND等可连接的广播报文。扫描设备200(主设备Master)开启BLE扫描，收到广播报文后，可通过发送连接请求报文(CONNECT_IND)与广播设备100建立连接。连接建立成功后，扫描设备200可向广播设备100发送数据报文(M->S Data)。广播设备100接收到数据报文后，在帧间距(T IFS)内向扫描设备200发送数据报文(S->M Data)。扫描设备200发送数据信息给广播设备100，或广播设备100与扫描设备200之间进行数据通信时，需要建立BLE连接。但是，建立BLE连接过程和维持BLE连接是需要增加工作，也带来功耗增加。其次，当前BLE连接数是有限制的，无法满足更多连接的业务。并且有些低成本的蓝牙beacon(ibeacon)或蓝牙芯片(mesh芯片)是不支持连接能力的。 Referring to FIG. 1C , it is a schematic diagram of a communication process of a BLE connection data packet provided by an embodiment of the present application. The broadcast device 100 (slave device) sends connectable broadcast messages such as ADV_IND through BLE. The scanning device 200 (the master device Master) starts BLE scanning, and after receiving the broadcast message, can establish a connection with the broadcast device 100 by sending a connection request message (CONNECT_IND). After the connection is established successfully, the scanning device 200 may send a data packet (M->S Data) to the broadcasting device 100 . After receiving the data packet, the broadcasting device 100 sends the data packet (S->M Data) to the scanning device 200 within the frame interval ( TIFS ). When the scanning device 200 sends data information to the broadcasting device 100, or performs data communication between the broadcasting device 100 and the scanning device 200, a BLE connection needs to be established. However, the process of establishing a BLE connection and maintaining a BLE connection requires increased work and also increases power consumption. Secondly, the current number of BLE connections is limited and cannot satisfy more connected services. And some low-cost bluetooth beacon (ibeacon) or bluetooth chip (mesh chip) do not support connection capability.
鉴于此，提供本申请实施例的蓝牙数据传输方法。在本申请实施例中，扫描设备200在开启BLE扫描，并接收到广播设备100发送的广播报文后，通过在扫描请求报文中新增扫描请求数据字段，将扫描设备中的数据信息同步至广播设备100。通过这种方式，在不增加设备功耗或少量增加设备功耗的情况下，可以实现数据信息的交互。In view of this, the Bluetooth data transmission method of the embodiment of the present application is provided. In the embodiment of the present application, after the scanning device 200 starts BLE scanning and receives the broadcast message sent by the broadcast device 100, it adds a scan request data field in the scan request message to synchronize the data information in the scanning device to the broadcasting device 100 . In this way, the interaction of data and information can be realized without increasing the power consumption of the device or slightly increasing the power consumption of the device.
在本申请实施例中，图1A所示的蓝牙通信***10是基于蓝牙协议的蓝牙***。即，广播设备100、扫描设备200可以均支持BLE的广播通信功能。具体的，广播设备100可以在BLE广播信道上广播BLE广播信号，扫描设备200可以扫描BLE广播信道并接收BLE广播信号。In the embodiment of the present application, the Bluetooth communication system 10 shown in FIG. 1A is a Bluetooth system based on the Bluetooth protocol.
