Ramon Roche	58b0a1f90d	mavsdk_tests: fix wall-clock sleeps in test_multicopter_basics Replace std::this_thread::sleep_for() with tester.sleep_for() to use simulation-aware sleep that accounts for speed factor under lockstep.	2026-02-18 11:04:06 +13:00
Ramon Roche	8e71a96cf7	mavsdk_tests: fix wall-clock timeouts to use simulation time Replace 5 functions that used std::future::wait_for() (wall-clock time) with poll_condition_with_timeout() (simulation time). This prevents timeouts from expiring prematurely when running at high speed factors under lockstep. Affected functions: - wait_until_altitude() - wait_for_landed_state() - wait_for_flight_mode() - start_and_wait_for_mission_sequence() - wait_until_speed_lower_than() Also remove debug printf statements from start_checking_altitude().	2026-02-18 11:04:06 +13:00
Julian Oes	704c05c428	navigator: add to lockstep This is an attempt to get the SIH CI tests more consistent.	2026-02-03 19:51:31 +13:00
Julian Oes	5c2c48f29d	mavlink: include in lockstep This is an attempt to get SIH CI tests to be more consistent.	2026-02-03 19:51:30 +13:00
Julian Oes	1fbe481a86	mavsdk_tests: reduce rate to avoid queueing of checks When we run this at 10x (or higher) we end up with too many checks queued up and by the time they execute the drone has slowed down.	2026-02-03 19:51:29 +13:00
Julian Oes	107393e6ad	simulator_sih: reduce drag According to Claude, the aerodynamic drag was way too high, and higher than e.g. Gazebo Classic. Another hint that it was too high is that the model 1102_tailsitter_duo_sih.hil had it at 0.2 as well. Reducing this, makes acceleration of the quadx more realistic and it starts passing CI tests where speed is checked. Without it, it tends to be too slow.	2026-02-03 19:51:28 +13:00
Julian Oes	5824bdb5fb	simulator_sih: implement lockstep by waiting for outputs Without this, we see test failures in CI as soon as CPU load is higher.	2026-02-03 19:51:27 +13:00
