47 *
48 * @details The WeChat Service contains two modules: WeChat Airsync Protocol and WeChat
49 * Pedometer Protocol.
50 *
51 * WeChat Airsync Protocol opens the data link between the device and the vendor server,
52 * which supports sending data from the device to the vendor's server, as well as the vendor's
53 * data to the device. The protocol also opens the data link between the device and the WeChat server.
54 * The data format between the device and the WeChat server is stipulated by WeChat, such as login,
55 * new message notification, etc.
56 *
57 * WeChat Pedometer Protocol is based on GATT protocol, which requires less hardware
58 * capability of the device, and the manufacturer does not need a back-end server (that is,
59 * only need to develop the device) to dock with WeChat. It allows pedometers to connect to WeChat
60 * and transmit steps, kilometers, calories, moving targets, etc.
