Bluetooth Share on Xiaomi: A Complete Guide to Fast File Transfer Technology

Have you ever tried to quickly send a photo or document from one Xiaomi to another, but standard Bluetooth was too slow? or faced a situation where Apple’s AirDrop or Google’s Nearby Share simply are not available on your device?

In this article, we will discuss in detail what Bluetooth Share is on Xiaomi, Redmi and other smartphones. POCO, How it works at the protocol level, how it differs from alternative solutions (such as Mi Share or Samsung’s Quick Share), and how to set up file transfers to avoid common errors. You will also learn which models support this feature, how to circumvent file size restrictions, and why transfer speeds sometimes fall to unacceptable values.

If you are a Xiaomi user and want to make the most of your device’s data sharing capabilities, this guide is for you. We’re not going to limit ourselves to basic instructions: here you’ll find technical nuances, comparative speed tests, and even ways to fix rare bugs that are not mentioned in the official documentation.

What is Bluetooth Share on Xiaomi and how does it work?

Bluetooth Share is a proprietary technology from Xiaomi that allows you to quickly share files between the brand’s devices using a combination of Bluetooth Low Energy protocols (BLE) Unlike classic Bluetooth, where speeds rarely exceed 2-3 Mbps, Wi-Fi Direct can reach speeds of up to 10-15 Mbps (under ideal conditions – up to 20 Mbps), which is comparable to Apple’s AirDrop.

Technology debuted in firmware MIUI 12 and has been widely distributed since MIUI 12.5 It is integrated into the system file sharing menu and automatically activates when another Xiaomi device with feature support is found nearby. Bluetooth Share does not require an internet connection or a mobile network – it is enough that both gadgets are in range of each other (usually up to 10 meters).

It is important to understand that Bluetooth Share is not just an accelerated Bluetooth, but a separate protocol that:

• 🔹 Uses it. BLE for searching and authenticating devices (saving battery life).
• 🔹 Switches to Wi-Fi Direct for file transfer (provides high speed).
• 🔹 Encrypts data according to the standard AES-128 (interception).
• 🔹 Supports background transmission (you can fold the application and continue to use the phone).

But there's a caveat: despite the name, Bluetooth plays a secondary role here, and the main load is on Wi-Fi Direct, so if your device has Wi-Fi turned off, the feature won't work (even if Bluetooth is active), which is a common cause of errors among users.

Bluetooth Share Distinguishes from Mi Share, AirDrop and Nearby Share

Many users confuse Bluetooth Share with other file sharing technologies, especially Mi Share, another Xiaomi proprietary solution. These are actually different protocols, although both are designed for Xiaomi ecosystem devices.

As you can see from the table, Bluetooth Share wins over Mi Share in speed and file size limit, but loses AirDrop in versatility (the latter works even between Mac and iPhone). MIUI Minimum delays in connection.

Another important point: Mi Share is gradually being replaced by Bluetooth Share in new versions MIUI. For example, in MIUI 14 Mi Share is hidden in the developer settings, and the focus is on Bluetooth Share as a more modern solution. If both features are available on your device, we recommend using Bluetooth Share - it is more stable and faster.
