telemetry_status advertise failed

[julianoes]

Recently in jMAVSim SITL I often see this on startup:

INFO  [mavlink] mode: Normal, data rate: 4000000 B/s on udp port 14570 remote port 14550
INFO  [mavlink] mode: Onboard, data rate: 4000000 B/s on udp port 14580 remote port 14540

ERROR [uorb] telemetry_status advertise failed

Presumably this has to do with uORB publication/subscription changes. FYI @dagar @mcsauder

[dagar]

I'm not seeing this locally. What are you running exactly? Is everything completely default?

[dagar]

If you see this again can you quickly check a few things?

mavlink status
listener telemetry_status
uorb top -1

[mcsauder]

I'm not seeing it locally either:

Ok, it only seems to happen with PX4_SIM_SPEED_FACTOR=20 make px4_sitl jmavsim.

[lamping7]

I saw this randomly yesterday when doing some multi-uav sims with ROS. I didn't see this topic before-hand. So, I don't have more than confirming that I saw "ERROR [uorb] telemetry_status advertise failed." I troubleshot a few things during that time, so hard to say more considering the environment changes I made during that time. I didn't touch speed factor.

[julianoes]

I have seen it at times without speed up as well.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[julianoes]

Doesn't seem to be happening anymore.

[julianoes]

This is happening again, when using Gazebo.

This has been fixed.
