MIUI and features of Bluetooth 4.2 protocols that support this smartphone.

In this article, we will not only examine the standard connection procedure through the official Mi Fitness app (formerly Zepp Life), but also alternative ways for third-party watches, as well as solve typical problems: from lack of response to device search to data synchronization failures. We pay special attention to the compatibility of firmware MIUI 10-12 with different versions of smartwatches, as it is critical for stable operation.
