Q&A


  1. The issue with XRCE-DDS: If Ethernet is up before DDS runs , all works ok. Otherwise, id the Ethernet or linux are not up then XRCE-DDs does not start. [Bug] UXRCE-DDS Client remains disconnected: does not attempt retries · Issue #27860 · PX4/PX4-Autopilot · GitHub
  2. If you run the rover , transitioning from stabilized/manual to position mode will get stalled in altitude mode (which does not make sense for a rover) doest not switch to the next mode which is position fixed and gets back to altitude mode. Relevant issue [Bug] Rover Failsafes into Altitude Mode (from Position) · Issue #28108 · PX4/PX4-Autopilot · GitHub
  3. fix(mc_pos_control): reject non-positive automatic vertical speed limits by JBotwina · Pull Request #28104 · PX4/PX4-Autopilot · GitHub : Adding many constraints would need a noticeable amount of code base change and adds many condiiton checks. For now the best is to rely on Metadata as a guide so the values are not chosen outside the value ranges.
  4. From @MaEtUgR PixRacer was flashed with the latest main and on the boot it goes out of ram . CC: @JulianOes
