Establishing Mavlink-connection between Arduino and Pixhawk

Ground Control Software MAVLink
6

Hi Bill!

Iā€™m using the Ardupilot-Software on a PX4 hardware. So if I get you right I have to use the common.xml to talk to the PX4? Sorry for the Noob-questions but I want to be sure that the wrong library is no error source (there will be a lot of others for sure :smile:)

Thanks for your help!
