Great, I am working in the same project. Can you please post a diagram of connecting between the pixhawk and the Neo Air? Thank you.

Thanks for your post!
can give details on the wiring?

This is the connection,

after that, you can
screen /dev/ttyS1 57600
and see the some character printed, but You won’t be able to read them as they are not ANSCII.
