The move will provide wearable device manufacturers with WeChat platform entry and server communication protocol support, and improve the fast, low-power wireless connectivity of wearable products.
The wearable device market is the next key development area of ​​intelligent hardware devices. The market potential is huge. Many Internet companies have begun to lay out the market for wearable devices, including Baidu, Xiaomi and Alibaba. Recently, another Internet giant, Tencent, has also entered the wearable market. Tencent WeChat, which has 438 million monthly active users, is about to open the WeChat API interface.
In the program launched by the United Nations General Assembly, the WeChat API will provide a seamless experience for wearable device users. Users do not need to download additional independent applications, and directly scan the QR code to follow the wearable device WeChat public platform. The connection can be established: the data of the wearable device is transmitted to the cloud server in real time, and after the data is processed, the cloud server returns the data to the wearable device via WeChat. In addition, you can also use the WeChat circle of friends to promote the rankings, word of mouth, topics, etc., but at the same time wearable devices will also put forward higher requirements for the technical capabilities of the WeChat interface.
