how to set the argument about the service "/get_frame".

[ou-ais]

Hi,
Thank you for your package.
I just launched the node "phoxi_camera.launch" and called a series of services .
But I really don't know how to set the argument about the service of "/get_frame" .
Could you tell me how to set it for getting the frame of point_cloud.

Best wish.

Hi,
get_frame require id parameter returned by /trigger_image service (/trigger_image trigger scan and /get_frame to publish point cloud to ros topics). If you call /get_frame service with argument -1 trigger image is called automatically and you do not have to call /trigger_image service (you call only /get_frame with argument -1 )

If you have any questions about service argument in future please see corresponding service file in srv folder first, usually, there are some notes to arguments.
