[UI-3131LE-M-GL] Could not set flash parameter info

[artifactz]

I have the UI-3131LE monochrome camera and it fails claiming

I've tried without any effect:

• changing color mode to mono8
• changing flash duration to 0 or -1
• changing image size to 808 x 608 or 800 x 600
• disabling auto exposure

I've also tried enabling ext_trigger_mode:

Timed out while acquiring image

It works with the uEye demo app. I assume my camera does not support setting flash parameters, so not setting them at all could solve the issue. How can I do that? Any help is appreciated.

Yes! Very nice, thank you. :+1: However, the error message still appears (twice), so maybe change it to a warning..?
