Hi @zwjgit There have only been three previous cases in which the RS2_OPTION_AUTO_EXPOSURE_LIMIT instruction has been used by RealSense users and all three of them experienced the object doesn't support option #85 error. There is no known solution and so I would recommend to not use this instruction, unfortunately.

You need to update the latest Firmware https://dev.intelrealsense.com/docs/firmware-releases, auto exposure limit is not supported in 0.5.12.07.150

@HViktorTsoi @MartyG-RealSense
folks tried with the latest firmware
Signed_Image_UVC_5_14_0_0.bin but it won't work.
Any ideas?
Thanks

@AndreV84 As mentioned above, the RS2_OPTION_AUTO_EXPOSURE_LIMIT has been reported on this support forum in three previous cases to generate a doesn't support option #85 error.

In #10771 a RealSense user had a different kind of problem with RS2_OPTION_AUTO_EXPOSURE_LIMIT

I recalled that there were recently problems reported with the related RS2_OPTION_AUTO_EXPOSURE_LIMIT_TOGGLE option at #11230 when using firmware 5.14.0.0.

A RealSense team member advised that the option was deprecated in 5.14.0.0 and recommends trying SDK version 2.54.0 when it is available.

In the meantime, a RealSense user in another case who had the same problem with RS2_OPTION_AUTO_EXPOSURE_LIMIT_TOGGLE found that downgrading from 5.14.0.0 to 5.13.0.50 resolved the issue in their particular case.

I am having the same issue, tried to downgrade the firmware, still doesn't work, searched for version 2.54, but it has not been released yet. Any solution?

Hi @lfescobarc The development source-code branch of librealsense at the link below - which is the next version of the SDK currently in development - becomes the latest 'master' version of the SDK when released, which will likely be numbered 2.54.0.
