No stream match for pointcloud chosen texture Process - Color about realsense-ros HOT 7 CLOSED

Hi @kenloumixx The message No stream match for pointcloud chosen texture Process - Color means that color frames are being dropped.

Because the message is accompanied by control_transfer returned error, index: 768, error: Resource temporarily unavailable, it suggests that the problem may be with the USB port or the USB cable.

Are you using the official 1 meter long USB cable supplied with the camera, please?

Does it make a difference if you unplug the micro-sized end of the USB cable from the base of the camera, turn the connector around the other way and re-insert it into the camera (USB Type-C cables are two-way insertion at the micro-sized end).

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

@MartyG-RealSense Yes, I'm using the official cable supplied with the camera.
And I also flipped up and down the micro usb cable and re-insert it into the camera but the warning still occurs.
I add initial_reset:=true args into the launch command but it stops at the line 'Resetting device...' and never goes on.

Does the FPS improve if you disable the RGB option auto_exposure_priority by inputting the instruction below into the terminal after launch has completed?

ros2 param set /camera/camera rgb_camera.auto_exposure_priority false

from realsense-ros.

@MartyG-RealSense I also ran the command ros2 param set /camera/camera rgb_camera.auto_exposure_priority false after run the rs_launch.py and it increases the pointcloud fps but not significantly.. around 1 hz increase

from realsense-ros.

How does the topic hz perform if you launch with ros2 run instead of rs_launch.py, please?

ros2 run realsense2_camera realsense2_camera_node --ros-args -p pointcloud.enable:=true

from realsense-ros.

@MartyG-RealSense The result of running the command ros2 run realsense2_camera realsense2_camera_node --ros-args -p pointcloud.enable:=true was the same low fps. Meanwhile, I changed my DDS from cyclonedds to fastrtps, then the fps increased over 10! I should have share my DDS setting haha thank you for your support :)

You are very welcome. I'm pleased to hear that you found a solution. Thanks very much for the update!
