setDeviceChangedCallback is not working in Ethernet Connection of Femto Mega

[Dineshkumar-VisAI]

I have tried to plug and unplug the Femto Mega camera with setDeviceChangedCallback, however, it works well in USB connection, and it is not working when I tried with Ethernet.

OS - Linux Ubuntu 20.04
platform - x86
Firmware version - 1.3.0
Orbbec SDK version - v1.10.18

I have tried with the HotPlugin.cpp Example code given in the SDK with the addition of calling the function ctx.enableNetDeviceEnumeration(true), but it doesn't work.

The output for the code is shown in the screenshot

Kindly help me resolve this issue.

• First, can your PC ping the device? Additionally, do you have multiple network cards on your PC?
• Currently, there is a bug in device discovery under multiple network cards.

Yes, the PC can ping the device. Also, I can connect the camera with context.createNetDevice(IP, port) API, but the only problem is that setDeviceChangedCallback is not working even with a single network card.
