PTP synchronization for Orbbec Gemini 335Le camera

[junwoonlee]

System Environment

• Hardware Info:
• CPU model: NVIDIA Jetson Orin AGX Devel kit 64GB
• Ubuntu Version: ubuntu20.04
• ROS Version: ROS2 Foxy

Description

Could you explain how to use PTP synchronization between the Gemini 335Le and the Jetson Orin AGX Developer Kit (acting as the PTP master)? Are there any required parameter settings when launching the camera with: "ros2 launch orbbec_camera gemini_330_series.launch.py"?

@junwoonlee You need to set enable_ptp_config to true in the launch file, and start the ptp4l service on the host as the master clock to synchronize time with the device.
