No Fix means the GPS is detected and working. It just hasn’t got enough position information yet. Are you inside or out? Does the GPS have a clear view of the sky?

i am outside, and clear to sky

Is there an antenna connected?

other than GPS antenna?
no only M9N unit is connected to flight contoller

Indeed. I’m asking if there is a GPS antenna either built in or connected. What you are showing is a valid configuration with no reception.

Let it sit for 15 minutes, powered on and see if anything changes.

Okay, yes GPS antenna built in!
