What's the recommended way to clear advanced mode on a D415?

Required Info
Camera Model	D415
Firmware Version	05.08.15.00
Operating System & Version	Ubuntu 16.04.03
Kernel Version (Linux Only)	#34~16.04.1-Ubuntu SMP Fri Jan 19 17:11:01 UTC 2018
SDK Version	2.9.1-0~realsense0.59

I've read that advanced mode is sticky in the D415, and will persist on the device once enabled. I was experimenting in realsense-viewer with depth detection thresholds, and now rs-enumerate reports "Advanced Mode: YES", even after power cycling the device, as advertised.

I want to go back to experimenting with streaming in the default mode. The rs2::device::hardware_reset() method looked like it might do the trick.

What's the recommended way to clear advanced mode? And is there any harm in clearing it every time I start up?

Cheers,

Jim

Hi @jallard-sr ,
You can turn on and off advanced mode using the RealSense Viewer.
Depending on the version you run, it's either under the "More" menu icon, or under "Advanced Mode" menu of the Stereo Sensor

Hi @jallard-sr
We provide such option in the Viewer. Prior to 2.9.1 it was under Controls > Advanced Mode > Disable Advanced Mode. In the upcoming 2.9.1 it will be a checkbox under More button you can un-check.
If you mean how to do this from code, it would be something like:

auto dev = context().query_devices().front();
auto adv = dev.as<rs400::advanced_mode>();
adv.toggle_advanced_mode(false);
adv.hardware_reset(); // I am not sure if the previous command will do this

@jallard-sr, regarding the code-snippet provided by @dorodnic, there is no need to do hardware reset (adv.hardware_reset()) after setting the advanced-mode to false because it's already done by toggle_advanced_mode(...) function.
Also, it is not harm to reset the advanced mode controls, but be aware that hardware reset will reset also the camera configuration such as controls, streaming and etc.

@icarpis When my application starts up, it is my intent to reset the camera controls, streaming, etc, to all of their defaults. Of course I want to retain the calibration and tuning for the device, but other than that I want to always start the camera like it just came out of the box. This way I can ensure that the camera is set up the way this particular application requires, and not be in a state that was useful to the last application.

The code snippet from @dorodnic was what I was looking for, though I have added a call to adv.is_enabled() before entering that block to not take extra startup time when it's not needed. I'll remove the call to ```hardware_reset`` when clearing advanced mode.

What your comment brings up is the question of whether there is other state, beyond advanced mode, that I may need to reset to ensure the camera is in a default state. I'm guessing that hardware_reset clears all volatile state, but I don't know the extent of non-volatile state/setup that I may need to revert.

The broader questions I should have asked first are the following: Is there is a method that can tell me if the camera is already in its default settings, and are there methods beyond toggle_advanced_mode and hardware_reset that are needed to get the camera back into its default state?

[icarpis]

There is no camera state that hardware_reset doesn't clear up. hardware_reset doing the same effect that physically unplug and plug back the camera does. So, hardware_reset is what you are looking for.
Regarding the additional questions, there is no method that can tell you if the camera in its default settings, and also, there are no other methods beyond toggle_advanced_mode and hardware_reset that get the camera back into its default state.

[dorodnic]

One notable exception might be RGB controls - if I recall correctly, they persist between power-cycles.

I'm closing this issue. please raise any questions or new issues if you will have any further questions.
