Why doesn’t Bluetooth work on Xiaomi’s bracelet?

Before you get into the setup, it’s important to understand why Xiaomi’s bracelet doesn’t find the phone or why the smartphone doesn’t see the gadget.

  • πŸ”‹ Battery discharge – if the bracelet charge is below 10%, Bluetooth can automatically shut down to save energy.
  • πŸ“± Older version of the app – Mi Fitness or Zepp Life require regular updates to work properly with new models of bracelets.
