Ava has a built-in Bluetooth signal that is activated every time you plug it into power.

When the light on top of Ava is blinking blue, this means that the Ava’s Bluetooth is activated and “findable”.
In order to transmit the data from your Ava to the app on your phone, your phone’s Bluetooth also needs to be switched on so that both devices recognize one another.

When you pair the Ava with the app, this pairing process uses that Bluetooth connection.

Once the Bluetooth connection between the Ava and your phone is established, the pairing process is complete and the light on top of your Ava should now be a solid blue.
