Mares Spa BLNK User Manual

Bluelink Universal

Bluelink Universal is a Bluetooth Low Energy (BLE) interface which allows a dive computer to
communicate with a smart device via a dedicated app. The smart device must be compatible with
Bluetooth Low Energy 4.0.

The app allows the smart device to connect to the dive computer in order to do the following:

- Read information (such as model and serial number)

- Download the logbook (data download)

- Upgrade the firmware (data upload)

Bluelink Universal is compatible with the following Mares dive computers:

- Icon HD Net Ready

- Matrix

- Nemo Wide (all versions)

- Puck

Bluelink Universal connects to a dive computer via the USB cable coming from the standard
interface (the one with which one connects to PC or Mac).

Operating mode.

When Bluelink Universal is not in use it remains in a low power mode in order to preserve the battery. This
is referred to as DeepSleep.

To establish a connection to the smart device follow this procedure:

• Place the Dive Computer into “PC Ready” mode. See dive computer manual for details.

• Connect the dive computer to the standard interface with the USB cable.

• Connect the other end of the USB cable to Bluelink Universal. Bluelink has two LEDs and

upon first connecting it to a dive computer in PC READY Mode, one LED will turn on to a steady
pink/purple for 5 seconds after which it will blink for 55 seconds. The other LED is green and will
blink throughout the 60 seconds.

• During these 55 seconds Bluelink Universal is ready to communicate with the smart device.

• If no communication takes place between Bluelink Universal and the smart device within these 55

seconds, Bluelink Universal returns to DeepSleep mode to preserve the battery and the LED turns
off. A connection attempt started now will fail because Bluelink Universal has returned to
DeepSleep mode. To wake up Bluelink Universal in order to initiate a new connection, disconnect
Bluelink Universal from the dive computer then reconnect it. The pink/purple LED will turn on
steady for 5 seconds then blink for another 55 seconds.

• To start a communication, open the app and initiate the connection (see app instructions on how
to do this).

• Once the connection has been established, the pink/purple LED turns green and the devices are
ready to communicate.

• If once the light has turned green no data is exchanged for 60 seconds, the LED starts blinking in
red to alert the user that the session is about to expire. If no data is exchanged for another 30
seconds, the connection is terminated and Bluelink Pro goes into DeepSleep.

• While the light is green or red, as soon as there is data exchange, the 60+30 second countdown is
reset to zero.

• If the connection is terminated by the app, for instance because the user closes the app, Bluelink
Pro will show a blinking pink/purple LED and a blinking green LED for 60 seconds, allowing a new
connection to be set up during this time.
