Smart IP43 Charger flashing blue light

I have recently added a Smart IP43 Charger to my system. It appears to be working and communicating with my phone and Ekrano, but it is displaying a flashing blue light adjacent to the Bluetooth symbol. Does anyone know if this indicates a fault?

Error states are a red LED as described here: 7. Monitoring

The blue LED flashing next to the bluetooth symbol indicates that bluetooth is active, and waiting for connection.

Thank you for the clarification.
