Possible reasons:
1. The mapping mode cannot be entered when the machine is in the following states: Upgrade, Abnormal, Paused, Returning to Dock, or Working.
We recommend trying:
1. Ensure the robot is not in any of the above states before attempting mapping.
2. Check if your phone's Bluetooth is turned on. If it's on but the app still can't find the Bluetooth, there might be an issue with the robot's Bluetooth module. Try restarting it.
3. Place the robot back on the charging dock to re-establish its location before attempting to enter mapping mode again.
