Driver disconnects Realsense

[samraise]

I'm trying to use a Realsense D435i camera alongside a FLIR Blackfly. When I launch the FLIR camera driver the Realsense driver fails to locate the d435i with the following error:

Could I please get some help on how I might be able to resolve this?

I am observing the same issue with other cameras. As soon as I run this driver, other cameras are disconnected.

Update: it seems to be an issue with Spinnaker. Launching spinview triggers the same bug.

Hi,
I met a similar problem. Both Realsense and FLIR cameras can be turned on but the FLIR camera node will be killed with the following errors:
[ERROR] [1712765563.427054041]: [SpinnakerCamera::grabImage] Failed to retrieve buffer with error: Spinnaker: Failed waiting for EventData on NEW_BUFFER_DATA event. [-1011]
[ERROR] [1712765563.427170181]: Failed to disconnect with error: [SpinnakerCamera::disconnect] Failed to disconnect camera with error: Spinnaker: Can't de-initialize camera. Camera is still streaming. [-1004]
Can anyone help me to find out why this happens and how to solve it? Thanks

The problem was solved by using the USB3 camera instead of the GigE camera. It would be fine if you launch the FLIR node before launching the RealSense node.
