Xiaomi Pro electric scooters are some of the most popular models among urban dwellers, but their functionality often goes undisclosed. Bluetooth allows access to advanced features: real-time speed tracking, firmware updates, setting up driving modes through the official Mi Home or Xiaomi Scooter app. However, many users face difficulties already at the connection stage - the Bluetooth module may not be detected, the scooter does not sync with the smartphone, or the application gives a Connection failed error.
In this article, we will analyze not only the basic algorithm for enabling Bluetooth on Xiaomi models. M365 Pro, Pro 2 and Pro 3, but also nuances that are not covered in standard instructions, such as why a scooter can not see a phone even after a module is successfully activated, how to reset the connection settings without losing data, and what to do if Bluetooth turns on but immediately turns off. Special attention will be paid to the diagnosis of hardware problems - when it is not the software that is to blame, but physical damage to the board or battery.
If you've already tried to connect and you've got an error, don't rush to bring a scooter to the service. 80% of the time, the problem is solved software-based by following the checklist from this article. And for those who are just getting acquainted with the device, we've prepared a step-by-step picture guide (see "Visual instructions").
What Xiaomi Pro models have Bluetooth and what are the differences?
Not all Xiaomi scooters are equipped with Bluetooth module – it depends on the generation and regional firmware.
| Model | Bluetooth version | Supported applications | Features of connection |
|---|---|---|---|
| Xiaomi M365 Pro (2019) | 4.0 | Mi Home, Xiaomi Scooter | It requires manual power switching, frequent communication interruption problems. |
| Xiaomi Pro 2 (2020) | 4.2 | Mi Home, Xiaomi Scooter, Ninebot | Automatic connection when switched on. OTA-update. |
| Xiaomi Pro 3 (2022) | 5.0 | Xiaomi Scooter, Ninebot (limited) | Improved connectivity: Connecting to 2 devices at the same time. |
| Xiaomi Electric Scooter 4 Pro (2023) | 5.2 | Xiaomi Scooter, Ninebot (Full Compatibility) | Support for low-energy regime (BLE). Fast pairing. |
Note that scooters sold in Europe and China may have different firmware. For example, European versions of the Pro 2 often lack the automatic Bluetooth connectivity feature due to local regulations. → Scooter.
If your model is not listed in the table, check for Bluetooth by external signs:
- 🔍 On the body under the steering wheel must be a sticker with the Bluetooth logo (blue icon).
- 📱 The instructions for the scooter mention the section "Wireless Connection" or "Bluetooth Pairing".
- 🔧 When turned on, the scooter emits a characteristic sound signal (short double beep), indicating the activation of the module.
Basic activation of Bluetooth: step-by-step instructions
Before starting, make sure that:
- 🔋 The scooter is charged at least 20% (at low charge, the Bluetooth module may not be turned on).
- 📱 Bluetooth and geolocation permission are enabled on the smartphone (required for the Mi Home application).
- 🔄 The scooter is within a radius of 1 meter from the phone (maximum distance for the first connection).
Now follow the algorithm:
- Turn on the scooter: press the power button on 2 It's a few seconds before the lights go off. 2/Pro 3 should sound.
- Activate the pairing mode: For M365 Pro: Hold the power button 5 for a second until the indicator starts flashing blue. 2/Pro 3: Press the power button twice at intervals in 1 second-second.
Connect via the app
- Open Mi Home or Xiaomi Scooter.
- Click Add Add the device (+) → Choose an electric scooter.
- Wait for your model to appear on the list and confirm the connection.
☑️ Preparation for connection
Critical detail: On Pro 2 models with firmware below 1.4.5, the pairing mode is turned on ONLY when the scooter is off. First press the power button for 5 seconds (off), then press again to activate Bluetooth.
If the scooter is not found in the annex:
- 🔄 Reboot Bluetooth on your phone (turn off/on in settings).
- 📱 Remove the cache of the Mi Home app in the smartphone settings.
- 🔧 Try connecting via another app (like Ninebot for Pro 3).
💡
If the scooter emits three short signals when trying to connect, it is a Bluetooth module error. Try resetting (see "Bluetooth Reset").
Top.-5 Errors in connection and how to fix them
Even after successful activation of Bluetooth, users face typical problems.
- Error "Connection failed" in the application Reasons: 📵 The scooter is already connected to another device (the Pro 3 supports multi-connection, but requires manual switching). 🔋 Battery charge below 15% – Bluetooth module shuts down to save energy. 📱 Outdated version of the app (update Mi Home to the latest version) Solution: Turn off Bluetooth on all previously coupled devices, charge the scooter and restart the app.
- Bluetooth turns on and off immediately, which is a typical problem for the M365 Pro with a worn-out battery. The module consumes ~0.5 watts, and at low voltage, the controller will force it to deactivate: 🔌 Connect the charger and try turning on Bluetooth when charging. 🔧 Check the battery contacts – oxidation can cause voltage drawdown.
The scooter is not displayed in the list of devices
Possible causes:
- 📡 Bluetooth module physically damaged (check after falls or moisture infestation).
- 🔄 Regional lockdown (e.g., scooters for the Chinese market may not connect to European phones).
- 📱 Conflict with other Bluetooth devices (on Android: Settings) → Bluetooth → Forget all the devices).
⚠️ Warning: After a hardware reset (method 2), the scooter may require recalibration of the brakes. E05 — Calibrate through an app or service center.
💡
Resetting Bluetooth does not affect the basic settings of the scooter (maximum speed, driving modes), but removes all the associated devices. After reset, the module returns to factory parameters, including the default name (for example, the default name, XMScooter_1234).
Visual Instructions: Where to Look for Indicators and buttons
A common problem for beginners is not understanding where Bluetooth controls are located, and the following are the diagrams for popular models:
For Xiaomi. M365 Pro and Pro 2:
For Xiaomi Pro 3 and 4 Pro:
- 🔘 Power button moved to the left side of the steering wheel (near the display).
- 🔵 Bluetooth indicator is built into the display – when activated, the icon is displayed 📶.
- 🎛️ Additional button MODE (under the display) – used to switch between coupled devices.
If your scooter is modified (for example, a non-standard display is installed), the location of the elements may vary.
- 🔊 Sound signals: one beep – on, two beeps – activation of Bluetooth.
Update firmware for stable Bluetooth
On Pro 2 and older models, Bluetooth instability is often due to outdated firmware, such as the versions below 1.5.0 had a bug with a communication interruption when connecting to an iPhone.
Method 1: Appendix (Recommended)
- Connect the scooter to Xiaomi Scooter.
- Go to Settings → Update firmware.
- If a new version is available, click Update and wait until it is completed (the scooter will restart).
Method 2: Manually through a firmware file
You will need to update automatically if:
- Download the firmware for your model from the official Xiaomi website (choose Global region or the official Xiaomi website). EUR).
- Unpack the archive and rename the file to firmware.bin.
- Place the file in the root of the microSD card (for Pro 3) or connect the scooter to the PC via USB-C.
- Press the power button. + brake for 10 seconds – the update will begin.
⚠️ Warning: Don't interrupt the update process! On the Pro 2, this can lead to a "bricking" of the controller (you need to flash through ST-Link). If the indicator flashes red for more than 5 minutes, contact the service.
After the update:
- 🔄 Reconnect Bluetooth (old pairing may reset).
- 📱 Update the Xiaomi Scooter app to the latest version.
- 🔧 Check the settings in the app – some settings (like Cruise Control) may reset.
