:people_holding_hands: Community Q&A (No deep technical discussions)


:exclamation: Guideline for asking a Question

  1. Specify what you are trying to achieve
  2. Specify what environment / platform you are using
  3. Prepare a Link or Document to help understand if possible
  4. First, ask the question on the Slack or create a Github Issue!
  5. If you take over 5 minutes for the question, please continue in Slack or a Github Issue.

Q.1 : adding namespaces to microdds_clients

https://github.com/PX4/PX4-Autopilot/pull/20466

Q.2: Flash overflowing, how do we fix this? - Jay

For example in this PR: https://github.com/PX4/PX4-Autopilot/pull/20237

Q.3: Pixhawk 6C not receiving RC data

https://discuss.px4.io/t/pixhawk-6c-flight-tests/28977/7

Q.4: HITL Fixed wing takeoff not working

https://github.com/Auterion/px4-jsbsim-bridge/issues/60

  • Probably because the actuator output mapping isn’t correct between the PX4 and Simulation
  • Probably not supported now.

There is a hanging PR to support HITL with jMAVSim, but it isn’t done yet.
https://github.com/Auterion/px4-jsbsim-bridge/pull/28

:construction_worker_woman: Project Updates


P.1 : Arbitrary Mag orientation feature - Junwoo

https://github.com/PX4/PX4-Autopilot/pull/20247

Before https://github.com/PX4/PX4-Autopilot/pull/20723 goes in, shouldn’t we get this in first? @bresch

P.2: State estimation wrong with VICON based real flight - Salvatore

https://discuss.px4.io/t/differences-between-simulation-and-real-drone/29923

  • State estimation issue: Should check the VICON data coming in (Frame of Reference, especially) > Probably not the case, since the stable release works well with VICON (Position mode).
  • Also, in Firmware side, MAVLink Enums have been changed, so the frames may have been changed (this custom firmware)
  • Possibly related: https://github.com/PX4/PX4-Autopilot/pull/20497
