@Alex-Kushleyev just learned you cannot set the exposure max to 1200. 1000 and 1500 work. If you set it to 1200 you get a vague IO error
ERROR: [ERROR] in _sensor_ioctl, ioctl failed: Connection timed out
ERROR: [ERROR] in voxl_cci_read, Failed ioctl call
ERROR: Failed CCI read
Just posting this here as an FYI to other wrestling with these new sensors.
@Alex-Kushleyev I will get the screenshots in a moment. lme_msv wasn't set and I noticed that power usage wasn't going down and figured there was just a bug in the config-reading code, so I recompiled with the default exposure value in the #DEFINE AE_{HIST,MSV}_DEFAULTS_TOF_LIOW2 overridden to 2000us and a printf inside the code chunk which sets it confirming that 2000 was being sent, so I am confident it was decreased. Good to know that setting lme_msv will get it to respect the exposure_max_us, that was pretty unclear.

And here's another where one of the sensors is given a longer range to ping over:
@Alex-Kushleyev We've also been playing with these sensors, and installed aluminum heat spreaders and even decreased exposure_max_us to 2000 and we are burning up the beta sensors regularly (get overheat warnings, and then eventually they stop drawing power and we only get sporadic "flashes" on the depth returns). We've been running at 5V. We're now almost out of sensors, and out of patience. I see you now have them in the Starling 2 - could you advise on how you have it set up there to avoid these overheating failures?
Edit: we don't have a fan or airflow over these, and our design is nominally water resistant which doesn't permit us to put these in an area with flow from the rotors. We have a fan drawing air over the VOXL itself internally but the previous gen ToF had absolutely no issue with being mounted away from air flow and working reliably. I am looking for a solution which permits that. Extended range is useless to me if the sensors die on the ground.
