The same way like in loiter. This should be further unified in the code
but at least we can increase safety in the case the takeoff altitude is
very high and the vehicle never reaches it but looses links.
* commander: send parachute command on termination
This sends the DO_PARACHUTE command to parachute component.
* commander: fix lying comments and printf
* commander: use one flag for termination triggered
This merges the duplicate flags _flight_termination_triggered and
_flight_flight_termination_printed.
* commander: correct variable name
* commander: always send tune with parachute
* commander: fix target_component for parachute cmd
The previous changes were wrong in that all commands were now sent to
the parachute component which doesn't make any sense. Of course only the
parachute command should be sent there.
When user override using the RC sticks is allowed, I would expect this
feature to also work in the case where GPS is lost and the vehicle goes
into a blind land/descent.
Without this commit, the vehicle would switch to Land mode and a pilot
could not take over control unless they switch to Altitude control in
a ground station.
With this commit, user override works as I would expect it and it will
switch to Altitude control allowing a pilot to recover in this
situation.
The calibration is not found in HITL mode. Therefore, I suggest to
ignore this step and assume the calibration is fine.
This mostly fixes the preflight check indicator in QGC, arming was (for
some reason?) already possible.
statfs accesses the file-system and can be blocking for an extended period. Since the SD card check is part of the preflight checks in the main thread of commander, it could block its execution and cause various issues. The SD card is only mounted in rcS during boot so the state will not change after the first check.
This is to avoid race condition with the yaw emergency estimator having
the same trigger delay of 1 second. Commander will now give more time to
EKF2 to reset itself before switching to altitude mode.
With this change we prevent the case where arming silently fails within
the first 10 seconds after boot.
Also, we now set the sensors as healthy as soon as the ekf is healthy,
and don't wait 10 seconds without actually checking.
