There is a blue light flashing on the Pebble.

Looks like the bluetooth connection between the Pebble and Base is broken.

To reestablish the connection,
please follow these steps:

Make sure your cellphone or any other Bluetooth enabled devices
are at least 3 metres away from the Pebble and Base.

1. Turn the Base and Pebble OFF

Make sure the Base and Pebble are not connected with the USB cable and then turn both
of them OFF. 

2. Lock the Pebble

On the back of the Pebble using the lock switch, “lock” the Pebble. 

3. Turn ON the Base first and connect USB Cable to the Pebble 

4. Unlock the Pebble and turn it ON

Both the Base and the Pebble should now have a solid white light.
If this does not solve your issue, please proceed to reset your Smart Nora.
