Any alternative to Mavros udp broadcast to QGC in ROS2?

[shazib2t]

Need some suggestion: I have been using ros1 and mavros for my companys multi uav and companion computer setup with 2.4ghz connection to GCS computer. Until now I have been successfully using the mavros with its udp broadcaster to the GCS computer for using QGC. But now if we have to move to ros2 and px4-ros-com what is my option as opposed to udp broadcaster to QGC. This is the only way I can communicate using QGC as of now.

@shazib2t I am in a very similar situation, and since this issue is a few weeks old I was wondering if you have made any progress? I'm currently in the process of trying to setup the ROS1 bridge, but this solution is cumbersome as I am forced to be on ubuntu 22.04 (ROS humble). MAVROS for ROS1 was great, but there doesn't seem to be any solution that is just as sexy for ROS2 (yet)

@ripdk12 I asked the same question on the PX4 discord channel and the response is, Answer here. Basically, the PX4 team wants us to use PX4_ROS_COM with MicroROS XRCE DDS. With this method, we have to use the MAVLINK router for GCS.

Mavlink router should work well for that in the meantime.

It's going to take a bit to get there, but ultimately I'd like to be able to simply run a PX4 mavlink (module) instance directly in ROS2 as a node.

So, You are using Mavlink_router ?
Is it working with ROS2?

I don't have a solution yet, but if you're interested in working on this please contact me.
