Can't connect or keeps disconnecting

If the device stays on "connecting" or keeps disconnecting, it may be due to one of the following reasons:

1. Only BLE connected, but classic Bluetooth did not. Make sure the Bluetooth device is fully connected.
2. Bluetooth permission not granted. Allow Bluetooth scan and connect permissions in your system settings.
3. Android requires location services to be on and the app to have location permission (used for BLE scanning).
4. Another device is already connected over Bluetooth and interferes with the current connection. Try disconnecting the other device and retry.
5. The Bluetooth device is not correctly paired in the system Bluetooth list. Forget the device and pair it again.

What to do

• In System settings → Bluetooth, confirm the device is paired.
• In the app, tap the matching device to connect.
• Make sure Bluetooth and location permissions are enabled.
• Disconnect other Bluetooth devices, then try connecting again.

Still can't find the device? See Bluetooth not found or shows "not connected".
