The reasons why Apple Bluetooth cannot be paired with Xiaomi are as follows:
1. Apple's system is ios system, which is completely different from Android system, so it cannot be paired with all Android phones.
2. Xiaomi phones use Android, so they can't be paired with Apple Bluetooth. Android is an open source operating system based on Linux, mainly used in portable devices. iOS is a mobile operating system developed by Apple Inc. in 2007 for devices including the iPhone, iPod touch, iPad, and Apple TV. Unlike Android and Windows Phone, iOS does not support non-Apple hardware devices.
