Community Announcement
uORB Explained Part 3 is out!
Community Q&A (No deep technical discussions)
Guideline for asking a Question
- Specify what you are trying to achieve
- Specify what environment / platform you are using
- Prepare a Link or Document to help understanding if possible
- First ask the question on the Slack or create a Github Issue!
- If you take over 5 minutes for the question, please continue in Slack or a Github Issue.
Q.1 : GPS Jamming indicator not shown on QGC - Seppe
- Would be nice to have an indicator in the QGC
https://github.com/PX4/PX4-Autopilot/blob/master/msg/sensor_gps.msg#L24
- Redirecting to latest version of document (main)
- Repo where feature is added : GitHub - SeppeG/PX4-GPSDrivers at septentrio-interference-detection
Q.2 : Wrong setting on Mixer (motor direction) confusion with Control Allocation - Safy
- https://review.px4.io/plot_app?log=d944e634-6b40-4f43-a580-ba9cfd6377d3
- Using Control Allocation. Slack Message link
- Control Allocation Motor direction setup was modified via QGC, but the Mixer was confused as to which direction the motor was spinning, and yaw control was bad.
- Is there a way we can “catch” a bad configuration?
- Couldn’t bring down the craft
- TODO : Create an issue to analyze how it happened
- Capture the control allocation status
- Redirecting to latest version of document (main)
Project Updates
P.1 : Web based Mission Planner / QGC - Fran
- Note : Dan Nix will be presenting on a similar topic, would be nice to sync with him
P.2 : Control Allocation User Doc is getting updated - Junwoo
- The goal is to make it easier for the user to configure the Control Allocation (Actuators)

General Discussions
D.1 : Fixed Wing Precision Landing - Ryan & Andrew
By having a GPS and a Barometer at the landing site, the landing coordinate can be pin-pointed. Currently the ‘Terrain Estimator’ is very unpredictable. Auto Landing is broken as well!

D.2 : Flash Overflow on Build Tests in the PR
https://github.com/PX4/PX4-Autopilot/pull/19374
- Targets like CUAV* can include a lot of code along with it, so it often overflows - Daniel
D.3 : X500 V2, with v5x hardware flight testing - Farhang
- Try to catch any weird behaviors / unusual beahvior
- Release v1.13.0-beta2 · PX4/PX4-Autopilot · GitHub

Issues
Slack
- Canceling a Mission in Flight - Ryan
- A user on discuss wants the ability to take his quad out of mission mode from his RC
Remote then when goes back into mission have the mission start over. I never really thought about it but this is actually a parameter that should be added so when you switch out of mission, waypoint count is reset then back to mission mode and it starts over.
From Discuss but actually an interesting idea for a parameter.
