Community Q&A

  • @JulianOes Found an issue that sometimes makes CI hang: If the simulation gets killed in the wrong moment then the main deamon gets killed but the individual processes started from the startup script still try to run and make CI time out. Making the startup script fail with the first failing command seems to already fix it but @bkueng proposed to kill the entire process tree instead to not have the entire startup script fail in case a command once fails. We should revise the exit strategy of SITL. Instead of a hard kill exit everything cleanly.

    Rarely the hardware test rack fails on a submitted pull request.

  • Servo calibration user experience issue on master found by @Paul_Riseborough
    @dagar is checking the suggestion. The way to trim will change soon with the new actuator configuration.

Project Updates

  • @MaEtUgR Proposing to have data link failsafe available in manual modes. Discussion results in not having this enabled by default and having a bitmask to opt into failsafes that are not hard requirements.
