NAVLink Blue – NMEA 2000 to Bluetooth

You can connect a water presence sensor to the NAVLink Blue. Go to the Bluetooth page and add the device named MSL01 Leak.

You will be prompted to change the device name. You can either keep the default name or assign a custom name (e.g., “Engine Room”) to better identify where water is detected.

This name will appear in the alert displayed on your compatible MFDs.

To connect a Calypso Wireless Wind Sensor, go to the Bluetooth page.

If the Calypso sensor is detected, it will appear in the Unregistered Devices section.

If you do not see the Calypso sensor, please follow the Calypso pairing process and verify the device using the Calypso mobile application.

IMPORTANT: The sensor will not connect if the Calypso mobile application is currently connected to the device. The Calypso sensor does not support multiple Bluetooth connections, so the mobile application must be disconnected before pairing it with the NAVLink Blue.

The Calypso sensor does not require any additional configuration. Simply click “Pair” to connect the device.

Because this sensor is often mounted in locations that are difficult to access, the NAVLink Blue supports Battery Status and DC Detailed Status PGNs.
This allows the remaining battery level of the sensor to be displayed on compatible MFDs, as shown on Garmin MFDs.

Note:
If the sensor cannot be detected by the Calypso mobile application, it will also not be detected by the NAVLink Blue. Make sure the device is powered and visible in the Calypso app before attempting to pair it with the NAVLink Blue.

The Bluetooth range of the Calypso sensor depends on the transmission power of the sensor itself and the installation environment. As a result, the achievable range may vary depending on mounting location and surrounding structures. This transmission power is defined by the Calypso device, and the NAVLink Blue cannot increase or extend it.

To connect a RuuviTag sensor, go to the Bluetooth page. If the RuuviTag is detected, it will appear in the Unregistered Devices section.

If you do not see the RuuviTag, please follow the Ruuvi pairing process and check the device using the Ruuvi mobile application.
Note that when the device is shipped, a battery isolation tab is installed. This tab must be removed for the device to operate.

Once the device appears in the list, click “Pair”.

After clicking the Pair button, the a configuration window will appear.

You will be able to configure the following parameters:

• Instance
  This allows multiple RuuviTag sensors to be connected and uniquely identified on the NMEA 2000 network.
  In most installations, leaving the instance set to 0 (default) will work correctly.
• Temperature Source
  Select the temperature source from the RuuviTag that will be transmitted and displayed on your MFD.
• Humidity Source
  Select the humidity source to be transmitted.
  Note that Garmin MFDs only display humidity when the source is set to “Outside Humidity.”

If you experience issues with the selected data source, you can unpair the device and repeat the pairing process, selecting a different source to troubleshoot the system.

For all sensors described in this document, only the pairing procedure with the NAVLink Blue is covered. For detailed information regarding installation, calibration, and operation of the sensors, please refer to the manufacturer’s user manual for each device.

The NAVLink Blue can be used in two modes:

• Server Mode

used to connect to Vakaros Atlas 2 or NMEA Remote application. When the device is operating in this mode, it cannot connect to external sensors.

• Client Mode

Client mode allows the NAVLink Blue to connect to external Bluetooth sensors such as Calypso, RuuviTag, Water Presence Sensor, etc.

If you want to connect external sensors, you must switch the device to Client mode:

1. Open the Settings
2. Click “Switch to Client Mode”.

Once the NAVLink Blue is in Client mode, it will be able to detect and connect to compatible external sensors.

The NAVLink Blue can be used in two modes:

• Server mode: used to connect to Vakaros Atlas 2 or NMEA Remote application. In this mode you can’t connect to other devices
• Client mode: used to connect to external sensors (Calypso, Ruuvi Tag and water presence sensors)

By default, the NAVLink Blue will start in Server mode. If you wish to change from client mode to server mode, please go to the settings page and click on “Switch to server mode”.
