Thank you for the response! I used a gain of 998, which was the max it would allow; anything over that values defaults to 998.

Here are the details of my setup:

Hardware: VOXL2 board, Stereo cameras (pair of MSU-M0072-2-00 Tracking Camera with IR Filters)

Software version: See output of voxl-version command below. I believe we are using the older 0.9 version of the SDK, which might have some issues with camera exposure commands (based on other posts on this forum). Also, looking at the code, I did find that src/config/config_defaults.cpp file has a min/max exposure for the OV7251 cameras to be 20 (=0.02ms) and 33000 (=33ms).

Also, a related question: the voxl-send-command exposure units are in Millisecond, correct?
