Revision history [back]

So, out of the top of my head,

• have you tried using picamera (https://picamera.readthedocs.io/en/release-1.13/) on the raspberry pi itself with the same configuration? Its a good idea to test if the hardware is working with native libraries outside of ROS before you try ROS packages. If the camera isnt working outside of ROS then there is no way it will work with raspicam_node
  • Since you are using a remote PC, you should ensure your ROS multiple machines set up is working properly, publish a simple float topic on raspberry pi and see if you can echo it from remote PC
• If step one and two is working then before using rqt_image_view on remote PC it is a good idea to rostopic echo the raw camera feed first and check if the topic is not empty.

Hope this helps.
