I am having more and more use for Foxy, ROS2, but I have robots that use Noetic ROS.
I really need a bridge and a way to go back and forth, any GOOD suggestions? 
@Lloyd
I was told that one can use this bridge package, but also told it is not recommended.
One of my test PCs, I’ve installed both Noetic and Foxy and source with difference setup script so that specific distro packages can be used.
So far I didn’t have much trouble with this, but I do not use this when testing for release as mixing development environment may cause unexpected behaviors.
