A. Ensure that your phone's Bluetooth is turned on and functioning properly. Go to Settings > Bluetooth and make sure it is enabled. If the app still loses signal, try restarting your phone and the sensor. This can help reset the connection.
B. Check for any obstructions between the sensor and your phone. Ensure that you are within the recommended distance (10-15 feet) and that there are no physical barriers like walls or metal objects that could interfere with the signal.
