ROS Noetic chrony no time sync

[nomah98]

Hello,

I am running ROS Noetic and chrony.

I am running the ntpd_driver with rosrun _shm_driver:=0 _time_ref_topic:=/mini_2/mavros/time_reference _fixup_enabled:=true __ns:=mini2. I do not seem to have any permissions issue.

My /etc/chrony/chrony.conf file includes refclock SHM 0 delay 0.5 refid ROS

Running sudo chronyc sources shows the ROS source as unreachable.

rosnode info /mini_2/ntpd_shm shows the node is subscribed to my /mini_2/mavros/time_reference topic, which is being published on via a recorded bag as a TimeReference message.

I am unsure why the source is still shown as unreachable. I installed via apt. I have used the repo previously and installed with catkin in ROS Melodic and have had success with the same setup. Any help would be appreciated

Do you have Setting system date to: <some-date> message? It looks like topic never got the message.

[nomah98]

I do not ever get that message. I can confirm messages are being published to that topic as a sensor_msgs/TimeReference

[nomah98]

Is there any other information via ROS or Chrony I can provide to help investigate this?

Can you try to send some TimeReference manually via rostopic?
Also could you please enable debug log for the node (use rqt)?
We are looking that message:

ntpd_driver/src/shm_driver.cpp

Line 155 in b8b9e1d

ROS_DEBUG_THROTTLE(10, "Got time_ref: %s: %lu.%09lu",

Any update on this issue?

Seems no. But note that time ref topic parameter was dropped. Please use remap.
