Hiyas @Samahu thank you for the quick response. I have gone into the sensor configuration parameters and was able to set the parameters!
Now I am just stuck in the “LISTENING” state. I have been looking at the documentation for my Garmin 18x LVC, Ouster OS2 LiDAR, and other posts on this website (this one the most: Possible reasons that might cause PTP time synchronisation failure). No matter what I try, the GPS does not seem to be recognized properly by the LiDAR. (Notably, my “gm_present=false” and I am unsure how to change this). I would appreciate any ideas to solve this problem.
I am also happy to share my pinout configuration, oscilloscope readings, and LiDAR sensor configuration information if it would prove useful to this discussion.
