MAVLink messages of the temperature and depth sensors

[zonit]

Hi,

I hope all is well. I have a question regarding MAVLink messages for the Blue Robotics temperature and pressure sensors.

Which specific MAVLink messages are used to display the sensor readings? From what I understand, the SCALED_PRESSURE3 message shows temperature, and for depth readings, I should refer to VFR_HUD. Is that correct?

Thank you very much in advance for your help.

Hi @zonit

@EliotBR

The compass and depth data can be retrieved from VFR_HUD , tilt and pitch are available in ATTITUDE , and temperature from an external pressure sensor like our Bar30 or Bar100 can be retrieved from SCALED_PRESSURE2 , while temperature from a dedicated temperature sensor like our Celsius can be retrieved from SCALED_PRESSURE3.

I’m planning to document that (and other components) more clearly in the ArduSub documentation, but am prioritising Cockpit and BlueOS docs at the moment.

Feel free to follow up if there are other values you’re wondering about
