On November 12, 2025, the Xiaomi Tag received certification from the Telecommunications and Digital Government Regulatory Authority of the UAE, model M2543T1, registration number ER53119/25. This Bluetooth tracker features item location capabilities similar to those of the Apple AirTag and Huawei HUAWEI TAG, allowing real-time connection to smartphones via Bluetooth technology. Beijing Xiaomi Mobile Software Co., Ltd. was granted a patent for “Methods and Devices for Finding Items” (Publication No. CN106877911B) back in 2021, which has similarities to the UWB technology patent used in the Apple AirTag.
A long-standing issue with the Android system has been the lack of a unified search mechanism, resulting in users lacking a useful app to bind items to prevent loss. With the release of Android 16, Google introduced a new application called Find Hub to replace the original Find My Device.
The UWB functionality of Google Find Hub is its core positioning technology, achieving centimeter-level accuracy for short-range item tracking. Even if the tracker or smartphone is offline, UWB can still assist in positioning through the Bluetooth signals of nearby Android devices.
Technical Principles
- Precise Positioning: UWB technology sends short pulse signals, measuring distance errors between devices to be less than 10 centimeters.
- Applicable Scenarios: Suitable for indoor searches for small items like keys and headphones, or outdoor tracking of luggage (such as luggage tracking services in collaboration with airlines).
How Google Find Hub Works
The working principle of Google Find Hub is to utilize the Bluetooth signals of Android devices for location tracking, functioning even when devices are offline. When devices are connected to the network, they scan for nearby devices via Bluetooth and securely send this information to the Find Hub network. Other devices that detect your device will also send this information to the network, helping you locate lost devices.
In the future, the functionality of Google Find Hub will become even more powerful, providing comprehensive search capabilities to directly compete with Apple’s Find My. The ST17H65B-PP chip from Lentz Technology empowers third-party manufacturers to implement Google’s Find Hub functionality. This chip features an ARM® Cortex™-M0 32-bit processor, equipped with 64K SRAM, 512KB Flash, and a secure hardware processor, supporting BLE with security features and over-the-air application updates. It is specifically designed for Google’s Find Hub service, offering high security, stability, and low power consumption. By integrating Google’s Find Hub SDK, this chip helps third-party devices better support Find Hub services, enabling device tracking and loss prevention.
