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.

[DanielDuecker]

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

[Chuong_Nguyen]

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.

Hi! Im using a flight controller and NanoPi neo air as a companion computer. I booted raspbian os on the NanoPi and used putty terminal, and i cant seem to get an IP or wifi connection, am I doing something wrong? Is there a good documentation on this process? Thanks!
