Issue Description

Hi everyone,
I'm using my L515 camera in a C++ code, right now in order to set it up I open Intel Realsense Viewer and set it there on "short range", but I would like to automatically have it set this way through my code, I looked up at the librealsenseSDK library but I really don't understand how to use JSON file with it. I assumed that saving the config into a JSON file (only once on Intel Realsense Viewer) and then using a certain method would work, yet after reading and trying for a couple of hours I don't know how to set up a rs2::device according to my camera and how to import the informations from my JSON file to my code.
Could anyone provide any help please,
best regards

Hi @CheCamCheCam The Visual Preset can be defined in C++ code instead of a preset. I hope that #9071 (comment) will be a helpful reference for implementing the L515 Short Range preset.

Hi, thank you for the link, I think it works as I managed to implement the lines in a way that doesn't cause errors and run the code but I wonder if there is a way to see if the modifications were made ? In any case thanks a lot for the help !

If an option can be set with SET.OPTION then its current status can also be read with GET.OPTION. I believe that a line like the one below should print the current value of the preset setting.

std::cout << "Preset = " << dev.query_sensors()[0].get_option(rs2_option::RS2_OPTION_VISUAL_PRESET) << std::endl;

The L515 presets have the number range 0-4, so Short Range should return a value of '4' as it is at the bottom of the list of 0-4 options.
