I got a D435i and it was DOA relative to the realsense-viewer. So I returned it. The replacement is also DOA, while my old D435 works. Maybe I need some instructions to get the new D435i to work, but what?

Looking at your logs, it seems to be a general problem with detecting the camera at all, rather than a problem that is specific to the RealSense Viewer.

Researching the problem and studying other cases, it seems that the error "Exception was thrown when inspecting properties of a sensor" tends to occur when there is an issue related to USB. This may be a problematic cable (not likely if you are using the short one supplied with the camera) or the camera being supplied with insufficient power by the USB port. I note though that your D435 is able to work, presumably on the same computer as the one you are having problems with when using D435i.

Do you have access to another computer that you can try the D435i on, please?

Tried a 5 year old i7 Windows 10 computer with version 2.17.1 of realsense-viewer.exe. Saw life spring to D435i in terms of stereo. Running on USB2.1, so not as good as old D435 on USB 3.2 machine (e.g. didn't see infrared streams).

Checked https://github.com/IntelRealSense/librealsense/releases and saw that version 2.12 (being used on my new Linux machine) supports D435, but doesn't claim support for D435i. Seems like I need to upgrade the version of the Intel code on the new Linux machine . Hope things don't go wrong because I'm in a deadline project and the old D435 works now.

Apologies for the delay in responding, I did not get a notification of your reply.

​Yes, support for D435i in the SDK is first listed in version 2.16.2.

It is certainly possible to go back to earlier SDKs if you have a problem, so long as you are not using a programming API instruction that is only in the newer SDKs. Good luck!​
