Bug report / Q&A

1- @Steve_John you could consider increasing COM_RC_LOSS_T to 1 second to check this again.

2- @Karukkuvel0Killis https://discuss.px4.io/t/ist8310-external-compass-showing-inconsistency/40758: check all the rotations and try to run it from the boot with the correct rotation. Then the calibration and see if it solves. Logging before and after boot will work.

3- @Karukkuvel0Killis How to use another MCU rather than stm32f100 as IO processor? : Maybe consider using IO for now to see if the problem resolves. Besides, taking a look into the specific board specs would be helpful to debug.

4- [Bug] CI: Upload Artifacts fails when test fails · Issue #23683 · PX4/PX4-Autopilot · GitHub
rover: add descend navigation state to land detection · PX4/PX4-Autopilot@81747f3 · GitHub
differential: Add stabilized and position mode (#23669) · PX4/PX4-Autopilot@2fd4150 · GitHub
@dagar maybe the way for now is to use v3.

PRs needing review

Maybe putting this for a point release or backport ?

Will be reviewed:

Pinged @DonLakeFlyer !

@dagar reviewed and commented, needs editing:

Need review on this PR: SF45 fixes to restart the state machine if sensor does not init correctly by dirksavage88 · Pull Request #23565 · PX4/PX4-Autopilot · GitHub

I think the Iris SITL test failed in CI, but not sure if this is happening with other PR’s.

Added to the thread Andrew,

Have a few QGC Prs I’d like to have reviewed :slight_smile:

Looking for another look at the Vertiq module integration PR please:

I’m experiencing issues with transmitting telemetry from my drone to the ground control station (GCS) using Wi-Fi broadcast (ESP-NOW) while running QGC on an ASUS controller. Specifically, I encounter a “manual control lost” error both before arming and during flight, which triggers fail-safe mode mid-flight. This problem only occurs with Wi-Fi broadcast; everything works fine when telemetry is sent over an access point.

Could this issue be related to the transmission rate of joystick data? I’ve noticed that the frequency in the QGC joystick tab is stuck at 25Hz, and changing the parameter doesn’t seem to have any effect. This problem resembles the issue described here: frequent "Manual control lost" message when joystick is used in QGC · Issue #13702 · PX4/PX4-Autopilot · GitHub.

Are there any parameters I can adjust to increase the joystick data transmission rate, and would it be advisable to do so?

Hey @Steve_John maybe try relaxing the COM_RC_LOSS_T parameter, start by increasing it to 1s, and go from there, but only if you don’t fly Stabilized or Acro where and can afford to have the stick input stuck at the last value for that amount of time. Thanks to @MaEtUgR @dagar for the response on the call.

  • Sensor issues were restored after the calibration. The issue is we didn’t accept the rotational values generated by the firmware after the calibration. We tried to resolve the issue by changing the rotation parameters manually which caused sensors inconsistency issue, every time we rebooted.
  • Created a feature request issue for IO firmware in the GitHub: https://github.com/PX4/PX4-Autopilot/issues/23698
    Thank you for your support

Thank you. I tagged Daniel and David on the issue. Hopefully, you can make it work.
