I feel like you should share more information. Is this a feature you suggest implementing? Any reference to this uORB? Requirements?

[avcuenes]

uORB messages are PX4 pub/sub message type. And plotjuggler can plot uORB messages after software ın the loop test as .ulg format. However, I want see uORB messages at real time not after flight.this feature will accelerate the development of autopilot algorithms.

I can write pluggin to handle mavlink messages to reach uORB messages

To have realtime plotting from px4 autopilot, you can also directly use existing bridge: the ros way: uorb => mavlink => mavros => plotjuggler https://github.com/mavlink/mavros or via dds/ros2 via micrortps https://docs.px4.io/main/en/middleware/micrortps.html uorb => micrortps => ros2 => plotjuggler

I am not personally going to work on this, unles as commercial support, sorry. If anyone implement this plugin, I will be happy to add the link in the official README

Hey! By the way, are you interested in writing a tutorial on how to set this up for this for the PX4 Community? It sounds like it would be very useful for a lot of developers out there!
