If you are using the ROVLe in an Omnitrack configuration on a BlueBoat (or are in a similar configuration) and you are connected to the BlueBoat's Ethernet, you may be able to send GPS and compass information to the BlueBoat via its MAVLink interface. You can configure the interface to use the BlueBoat's IP address and system (vehicle) ID.&#x20;

{% hint style="info" %}
Make sure the addresses of the primary and secondary MAVLink interfaces are different. If both are set to the same address it will put the ROV autopilot into an error state.
{% endhint %}
