DeviceTemperatureSelector parameter not value

[sebasferruiz]

Hello,

When trying to launch the camera in ros2 we get the error
DeviceTemperatureSelector: Value unavailable
ERROR Invalid value
We have tried changing this parameter in the params.yaml file and nothing works. We have tried Main and Sensor (since these were the possible values according to the manual) We are using the 1800 U-507c camera.

Would appreciate your help

According to the Vimba library (from AVT), there are a few possible reasons the ROS driver would print that warning. See here:

The model you mention (1800 U-507c) is an alvium camera, which has different features than the Mako camera I've tested this driver with.
According to the Alvium features reference, you have the following possible values:

• Mainboard
• FpgaCore
• PhyCore

Feel free to open a PR to add more default values to the existing usb_1800_U.yaml (which you should be using instead of params.yaml).
