3 FDAP INSTALLATION

BLE Status LED (Green)

BLE Status LED provides the different states of BLE connection:

• ALWAYS OFF - Advertisement off, controlled through WDM UI, typically

done when FDAP already joined the network.

• 10 seconds OFF, 1 second ON – FDAP Gen3 in advertisement mode, waiting

for connection from BLE Central (ex: Mobile App).

• 2 seconds OFF, 2 seconds ON – FDAP Gen3 is connected to BLE Central (ex:

Mobile App). NOTE: Only connected, not yet BONDED.

• 1 second OFF, 1 second ON - FDAP is bonded to BLE Central (ex: Mobile

App).

• ALWAYS ON - FDAP is ready for secure data exchange with BLE Central

(ex: Mobile App).

• And special case of BLE module firmware download, where LED is toggled

every 250ms (that is 250ms ON, 250ms OFF). NOTE: When BLE module

firmware download is in progress, connection to FDAP Gen3 by BLE Central

(ex: Mobile App) is not possible.
