Yaapu LUA Fully Functional and Supported with PX4 Firmware

Cool project! Is this still state of the art in late 2021?
Would be great to see if that setup can be simplified for PX4…kind of similar to the one for ardupilot.
Btw, what is your take on FPort? That seems to be really cool, no? Are there any preliminary trials in that direction? (There seems to be a discussion here). Thx!
