Lumen lights not working on Navigator

General Discussion
1

Just set up a new ROV with new Navigator controller and cant get the Lumenn lights to work. The thrusters work and the gripper works but no lights. I can see the controller activating buttons 13 & 14. Ive tested the lights by directly powering the signal channel and they work. I’ve also tried plugging them into channel 9 instead of the gripper and they work using the gripper controls but in channel 13 where they should I get nothing.
In the Lights tab of the vehicle setup I get a QGroundControl popup saying Parameters are missing from the firmware. Missing params: 1:BRD_PWM_Count
I have the latest firmware installed in Blue-OS and latest version of QGC.
In then lights setup page the dropdown boxes for Lights 1 & 2 are blank and the only drop down option is ‘Disabled’… is that normal??

Any advice to fix this gratefully accepted.
Thanks,
Gavin.

Should add that in the Button Assignment page I also have channels 13,14 setup for Lights1_dimmer and lights1_brighter

Hi @nemorov -
How many sets of lights are you trying to connect? What port of the navigator are they connected to?

We don’t recommend using the latest version of QGC - version 4.2.8 is listed on our technical reference.

Checkout this resource and verify the servo parameters in the third column of the table are set under Autopilot Parameters in BlueOS.

Generally Blue Robotics is moving away from QGC, in favor of Cockpit!

Thanks Tony,

I have one set of 4 lumen lights bought as a pre wired set a while back.
They are plugged into the Servo13 port as per the Navigator instructions.
I’ll check the Servo Parameters when back in the workshop tomorrow (I’m in the UK). Meanwhile I’ll look at installing Cockpit this evening and look at moving over to that.
Thanks.

Hi Tony,

Loaded and setup Cockpit and Lights magically working as expected so all good.
Thanks for the help.

Gavin.

If I attached it to the servo16 how do I change in the cockpit the mapping for that servo if not default servo13?

Hi @nurjan14,

You can configure the lights output channel via Vehicle Setup / Configure / Lights in BlueOS, or just manually set the SERVO16_FUNCTION parameter to RCIN9.

There is some existing documentation about this, but I agree it is less clear than it could be, and I’m intending to improve that when I return to working on the ArduSub docs. We have at least recently updated the naming so the parameter value label will be RCIN9/Lights1Level in future, but it may take a while for that to appear for a stable/beta release of ArduSub.
