There is a possibility that the Bluetooth connection with the sensor has been interrupted.
Please check the following:
- Check the remaining battery charge of the sensor.
- Confirm that the sensor's Bluetooth light (blue) is flashing.
- If the Bluetooth light (blue) is not flashing, try restarting the sensor.
- If the blue light does not light up, even when the Bluetooth button is pressed, charge the sensor, as there is a possibility that the sensor's remaining battery charge is at empty.
Refer to the following on the behavior of the flashing lights.
