Issue Description
Hello, I am trying to use a raspberry pi 5 with realsense-ros to run some tflite models. I have a problem with the framerate since the messages from the camera node are sent at ~13.5Hz and not 30Hz as expected. Since this happens even when the camera node is the only node running I wanted to ask if there are known possible causes for this problem.
Hi @TheSav1101 Are you using depth only or are depth and color enabled?
If both depth and color are published, when you have the camera again please test whether the FPS frequency improves if you add auto_exposure_priority:=false to your launch instruction. For example:
ros2 launch realsense2_camera rs_launch.py auto_exposure_priority:=false
Hello, @MartyG-RealSense I am currently publishing depth and color, but now that you mention it I probably don't need both, I will make a couple of tests on Friday with different settings. Sorry for the trouble, I didn't even think about that...
