Issue Description

I have been experiencing two issues with my Realsense L515 camera and camera node:

1. Overheating issue: The camera gets "feverish" and heats up after running for a while. I suspect this is an issue with the hardware and would appreciate any suggestions on how to deal with this.

2. Streaming error: When running the realsense2_camera_node, I get the following error messages:

   [realsense2_camera_node-1] [INFO] [1683896366.588692908] [camera.camera]: RealSense Node Is Up!

   [realsense2_camera_node-1] Stream stoped. May be recoverable,1.6839e+12,Error,Hardware Error

   I have no problem to run my code when the stream is not stopped on the start of the day. Additionally, I have written a simple code to display the image from the camera, but the image window is showing black.

Thank you for your assistance.

Hi @iyeszin Could you first try unplugging the micro-sized end of the USB cable from the base of the L515 camera, reversing the connector's orientation and plugging it back into the camera, please (USB-C cables are two-way insertion at the micro-sized end). A characteristic of the L515 model is that it can perform better when the micro-sized connector is oriented in one particular direction of the two available.

The L515 can feel hot to the touch after a while when touching the casing, so this is not necessarily an indication of a fault.

Hi @MartyG-RealSense, I tried it with 2 different cables in both way insertion and the streaming error still occurs.

Does the error still occur if you add initial_reset:=true to your launch instruction to reset the camera at launch?

Do you have access to the RealSense Viewer tool, and if you do then is the camera able to stream normally in the Viewer?

Hi @iyeszin Do you have an update about this case that you can provide, please? Thanks!

Hi @MartyG-RealSense, I had added initial_reset:=true when launching. I had the RealSense Viewer tool. For your information, the camera is able to stream normally without starting the ros node at the same time, however, it show black screen when I run with ros node. I'm currently working on with another camera, I will come back to check the camera when I have time.
