Our C++ app cannot detect Femto Mega I camera

We’re developing a C++ app using the Orbbec SDK v1.10.12. We have two Orbbec cameras:

  1. Femto Mega with firmware version 1.2.8 (IP: 192.168.5.153)
  2. Femto Mega I with firmware version 2.0.2 (IP: 192.168.5.95)

The problem is that only the first camera can be detected by our C++ app.
However, the Orbbec Viewer can connect to the problematic camera.

UPDATE:
Orbbec Viewer prints the following logs for Femto Mega I:
