I have bought Pixhawk PX4 Autopilot PIX 2.4.8 with 433 telemetry and M8N GPS.

Next, when I get to calibrating the “sensors”, specifically the last one - “level horizon” - I get:
“[cal] calibration started: 2 level. Attitude estimator not running - check system boo. [cal] calibration failed: level”
And the message that I get from “loudspeaker” (on top of the panel in QGroundControl) is:

But the main issue is of course the baro sensors and mag inconsistency.
I am a newcomer to the field, so I have only a vague idea of what an “FTDI cable” is. Just saw it on Internet. However, from what I have read, I can see the NSH shell through a USB connection in QGroundControl:
