:loudspeaker: Community Announcement


1 MONTH until the PX4 Dev Summit!! :tada:

: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 understanding 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 : Mission index - Safy

Does anyone know why MAVROS topic /mavros/mission/waypoints would give the current_seq: 2 when the list is empty ? shouldnt it be 0 or something that means nothing like -1 ?

  • Posted on Slack
  • Creating a software using Mission in PX4
  • Answer
    • Try to capture the mission_ uORB message through console (MAVLink Console, QGC)

Q.2 : RC input & Joystick - Safy :joystick:

  • Currently when PX4 starts up, it registers Joystick, then uses RC, etc…
  • Feedback
    • Fix for this would be an UI change where it would expose this parameter (COM_RC_IN_MODE) selection - Matthias
    • It’s not safe to configure Joystick to control when RC is already in control :thinking:
    • We could also alert users with an MAVLink message so that it would appear on QGC - Daniel
  • We could add this alert message for the case when an input (e.g. Joystick) gives valid data, but is not configured to be used.
  • TODO : @dagar will check ManualControl module to check if we can add message alerts.
