So I've got the PXFmini to work on mission planner on windows and APM planner on windows only works sometimes, but I want to use my Rpi3 as a GS, so I have APM planner on it.
I'm connecting to the sik via a FTDI adapter and that works, what I am having problems with is when I connect to my Rpi3 with ubuntu I choose my serial port ttyUSB0 and use 57600 baud and it gets hung up on "getting parameters"
I know its not my hardware because it works fine in mission planner on windows.
I have changed my permissions to allow my user to access serial ports. And I cannot run the APM planner as SU as it gives me a permission error.
