The implementation before this change had two timeouts, a hard-coded
timeout of 0.5 seconds as well as a by param configurable timeout with
certain failsafe actions set.
This change aims to fix two problems:
1. The hard-coded offboard timeout can be triggered easily with sped up
lockstep simulation. Since i t is hard-coded it can't be adapted to
the speed factor.
2. The offboard signal can time out but no action will be taken just
yet. This means we end up in an in-between stage where no warning or
failsafe action has happened yet, even though certain flags are set
to a timeout state.
This patch aims to fix this by unifying the two timeouts to the existing
configurable param. The convoluted double timeout logic is replaced by a
simple hysteresis.
For anyone that has previously not changed the default timeout param (0),
the param will now be changed to 0.5 seconds which reflects the
previously hardcoded time. For anyone with a specific timeout
configured, the behaviour should remain the same.
Also, going forward, timeouts lower than 0.5 seconds should be possible.
Sometimes in CI for VTOL we saw disarms before the spoolup and ramp were
over and the takeoff would actually happen. By raising the auto-disarm
time we should be able to work around this and get CI less flaky.
This reverts commit be35c4857b.
This would only work for integer math, so for simulation speed-up. For
speeds slower than realtime we need floating point.
- this is one of the last pieces of the system that still depend on DriverFramework
- add new SIM_GPS_NOISE_X parameter for optionally increasing the GPS noise multiplier (was previously a gpssim command line option)
- add SIM_x_BLOCK parameters to block sensor publication
- SIM_GPS_BLOCK
- SIM_ACCEL_BLOCK
- SIM_GYRO_BLOCK
- SIM_MAG_BLOCK
- SIM_BARO_BLOCK
- SIM_DPRES_BLOCK
This new airspeed module does:
-runns an airspeed validator for every airspeed sensor present, which checks measurement validity and estimates an airspeed scale
-selects another airspeed sensor if for the current one a failure is detected
-estimates airspeed with groundspeed-windspeed if no valid airspeed sensor is present
-outputs airspeed_validated topic

When simulating with lockstep we can raise the speed by setting the env
variable `PX4_SIM_SPEED_FACTOR`. Some inputs like RC, MAVLink heartbeats
from a ground station, or offboard controls via MAVLink are still at the
normal speed which leads to timeouts getting detected in PX4.
To work around this issue we can automatically multiply the timeout
parameters by the speed factor.
The typhoon has a 6011_typhoon_h480.post script that got matched as well.
Now we exclude all files that contain a dot (apparently it's not so easy
to do generic pattern matching in a portable way, but this works).
This uses the systems default shell:
- Ubuntu: dash
- Fedora: bash
Since bash is invoked via /bin/sh, it operates in POSIX mode:
https://tiswww.case.edu/php/chet/bash/POSIX
- remove '# Ignore the expand_aliases command in zshell.'
Not needed because the shell operates in POSIX mode
- [[ is bashism -> use [
- autostart_files=( $autostart_file_match )
is not supported in dash, so use 'ls'
- shellcheck runs the dash flavor, since dash is a minimalistic shell.
Tested on dash & bash.
